The Persian monarch was really, in his force, a petty prince compared

to the Grecian republics, and therefore it behoved him, from views of

safety more than from emulation, to interest himself in their quarrels,

and to support the weaker side in every contest. This was the advice

given by Alcibiades to Tissaphernes, and it prolonged near a century

the date of the Persian empire; till the neglect of it for a moment,

after the first appearance of the aspiring genius of Philip, brought

that lofty and frail edifice to the ground with a rapidity of which

there are few instances in the history of mankind.

The successors of Alexander showed an infinite jealousy of the balance

of power, a jealousy founded on true politics and prudence, and which

preserved distinct for several ages the partitions made after the death

of that famous conqueror. The fortune and ambition of Antigonus

threatened them anew with a universal monarchy, but their combination

and their victory at Ipsus saved them; and in after times we find that

as the Eastern princes considered the Greeks and Macedonians as the

only real military force with whom they had any intercourse, they kept

always a watchful eye over that part of the world. The Ptolemies, in

particular, supported first Aratus and the Achæans, and then Cleomenes

King of Sparta, from no other view than as a counterbalance to the

Macedonian monarchs; for this is the account which Polybius gives of

the Egyptian politics.

The reason why it is supposed that the ancients were entirely ignorant

of the balance of power seems to be drawn from the Roman history more

than the Grecian, and as the transactions of the former are generally

the most familiar to us, we have thence formed all our conclusions.

It must be owned that the Romans never met with any such general

combination or confederacy against them as might naturally be expected

from their rapid conquests and declared ambition, but were allowed

peaceably to subdue their neighbours, one after another, till they

extended their dominion over the whole known world. Not to mention

the fabulous history of their Italic wars, there was, upon Hannibal’s

invasion of the Roman state, a very remarkable crisis which ought to

have called up the attention of all civilized nations. It appeared

afterwards (nor was it difficult to be observed at the time​[22]) that

this was a contest for universal empire, and yet no prince or state

seems to have been in the least alarmed about the event or issue of the

quarrel. Philip of Macedon remained neuter till he saw the victories

of Hannibal, and then most imprudently formed an alliance with the

conqueror, upon terms still more imprudent. He stipulated that he was

to assist the Carthaginian state in their conquest of Italy, after

which they engaged to send over forces into Greece, to assist him

in subduing the Grecian commonwealths.

The Rhodean and Achæan republics are much celebrated by ancient

historians for their wisdom and sound policy; yet both of them

assisted the Romans in their wars against Philip and Antiochus. And

what may be esteemed still a stronger proof that this maxim was not

familiarly known in those ages, no ancient author has ever remarked the

imprudence of these measures, nor has even blamed that absurd treaty

above-mentioned made by Philip with the Carthaginians. Princes and

statesmen may in all ages be blinded in their reasonings with regard

to events beforehand, but it is somewhat extraordinary that historians

afterwards should not form a sounder judgment of them.

Massinissa, Attalus, Prusias, in satisfying their private passions,

were all of them the instruments of the Roman greatness, and never seem

to have suspected that they were forging their own chains while they

advanced the conquests of their ally. A simple treaty and agreement

between Massinissa and the Carthaginians, so much required by mutual

interest, barred the Romans from all entrance into Africa, and

preserved liberty to mankind.

The only prince we meet with in the Roman history who seems to have

understood the balance of power is Hiero, King of Syracuse. Though

the ally of Rome, he sent assistance to the Carthaginians during the

war of the auxiliaries: “Esteeming it requisite,” says Polybius,

“both in order to retain his dominions in Sicily and to preserve the

Roman friendship, that Carthage should be safe; lest by its fall

the remaining power should be able, without contrast or opposition,

to execute every purpose and undertaking. And here he acted with

great wisdom and prudence; for that is never, on any account, to be

overlooked, nor ought such a force ever to be thrown into one hand as

to incapacitate the neighbouring states from defending their rights

against it.” Here is the aim of modern politics pointed out in express

terms.

In short, the maxim of preserving the balance of power is

founded so much on common sense and obvious reasoning that it is

impossible it could altogether have escaped antiquity, where we

find, in other particulars, so many marks of deep penetration and

discernment. If it was not so generally known and acknowledged as

at present, it had at least an influence on all the wiser and more

experienced princes and politicians; and indeed, even at present,

however generally known and acknowledged among speculative reasoners,

it has not, in practice, an authority much more extensive among those

who govern the world.

After the fall of the Roman Empire the form of government established

by the northern conquerors incapacitated them in a great measure

from further conquests, and long maintained each state in its proper

boundaries; but when vassalage and the feudal militia were abolished

mankind were anew alarmed by the danger of universal monarchy, from

the union of so many kingdoms and principalities in the person of the

Emperor Charles. But the power of the house of Austria, founded on

extensive but divided dominions, and their riches, derived chiefly from

mines of gold and silver, were more likely to decay, of themselves,

from internal defects, than to overthrow all the bulwarks raised

against them. In less than a century the force of that violent and

haughty race was shattered, their opulence dissipated, their splendour

eclipsed. A new power succeeded, more formidable to the liberties of

Europe, possessing all the advantages of the former and labouring under

none of its defects, except a share of that spirit of bigotry and

persecution with which the house of Austria were so long and still are

so much infatuated.

Europe has now, for above a century, remained on the defensive against

the greatest force that ever perhaps was formed by the civil or

political combination of mankind. And such is the influence of the

maxim here treated of, that though that ambitious nation in the five

last general wars has been victorious in four,​[23] and unsuccessful

only in one,​[24] they have not much enlarged their dominions,

nor acquired a total ascendant over Europe. There remains rather room

to hope that by maintaining the resistance some time the natural

revolutions of human affairs, together with unforeseen events and

accidents, may guard us against universal monarchy, and preserve the

world from so great an evil.

In the three last of these general wars Britain has stood foremost in

the glorious struggle, and she still maintains her station as guardian

of the general liberties of Europe, and patron of mankind. Beside her

advantages of riches and situation, her people are animated with such a

national spirit, and are so fully sensible of the inestimable blessings

of their government, that we may hope their vigour never will languish

in so necessary and so just a cause. On the contrary, if we may judge

by the past, their passionate ardour seems rather to require some

moderation, and they have oftener erred from a laudable excess than

from a blameable deficiency.

In the first place, we seem to have been more possessed with the

ancient Greek spirit of jealous emulation than actuated with the

prudent views of modern politics. Our wars with France have been begun

with justice, and even, perhaps, from necessity; but have always

been too far pushed from obstinacy and passion. The same peace which

was afterwards made at Ryswick in 1697 was offered so early as the

ninety-two; that concluded at Utrecht in 1712 might have been finished

on as good conditions at Gertruytenberg in the eight; and we might have

given at Frankfort in 1743 the same terms which we were glad to accept

of at Aix-la-Chapelle in the forty-eight. Here then we see that above

half of our wars with France, and all our public debts, are owing more

to our own imprudent vehemence than to the ambition of our neighbours.

In the second place, we are so declared in our opposition to French

power, and so alert in defence of our allies, that they always

reckon upon our force as upon their own, and expecting to carry on war

at our expense, refuse all reasonable terms of accommodation. _Habent

subjectos, tanquam suos; viles, ut alienos._ All the world knows that

the factious vote of the House of Commons in the beginning of the last

Parliament, with the professed humour of the nation, made the Queen

of Hungary inflexible in her terms, and prevented that agreement with

Prussia which would immediately have restored the general tranquillity

of Europe.

In the third place, we are such true combatants that, when once

engaged, we lose all concern for ourselves and our posterity, and

consider only how we may best annoy the enemy. To mortgage our revenues

at so deep a rate in wars where we are only accessories was surely the

most fatal delusion that a nation, who had any pretension to politics

and prudence, has ever yet been guilty of. That remedy of funding—if

it be a remedy and not rather a poison—ought, in all reason, to be

reserved to the last extremity, and no evil but the greatest and most

urgent should ever induce us to embrace so dangerous an expedient.

These excesses to which we have been carried are prejudicial, and

may perhaps in time become still more prejudicial another way, by

begetting, as is usual, the opposite extreme, and rendering us totally

careless and supine with regard to the fate of Europe. The Athenians,

from the most bustling, intriguing, warlike people of Greece, finding

their error in thrusting themselves into every quarrel, abandoned all

attention to foreign affairs, and in no contest ever took party on

either side, except by their flatteries and complaisance to the victor.

Enormous monarchies are probably destructive to human nature—in their

progress, in their continuance,​[25] and even in their downfall,

which never can be very distant from their establishment.

The military genius which aggrandized the monarchy soon leaves the

court, the capital, and the centre of such a government; while the

wars are carried on at a great distance, and interest so small a

part of the state. The ancient nobility, whose affections attach

them to their sovereign, live all at court; and never will accept of

military employments which would carry them to remote and barbarous

frontiers, where they are distant both from their pleasures and their

fortune. The arms of the state must therefore be trusted to mercenary

strangers, without zeal, without attachment, without honour, ready

on every occasion to turn them against the prince, and join each

desperate malcontent who offers pay and plunder. This is the necessary

progress of human affairs; thus human nature checks itself in its

airy elevations, thus ambition blindly labours for the destruction of

the conqueror, of his family, and of everything near and dear to him.

The Bourbons, trusting to the support of their brave, faithful, and

affectionate nobility, would push their advantage without reserve or

limitation. These, while fired with glory and emulation, can bear the

fatigues and dangers of war; but never would submit to languish in the

garrisons of Hungary or Lithuania, forgot at court, and sacrificed to

the intrigues of every minion or mistress who approaches the prince.

The troops are filled with Cravates and Tartars, Hussars and Cossacks,

intermingled perhaps with a few soldiers of fortune from the better

provinces; and the melancholy fate of the Roman emperors, from the same

cause, is renewed over and over again till the final dissolution of the

monarchy.

OF TAXES.

There is a maxim that prevails among those whom in this country we call

“ways and means” men, and who are denominated financiers and maltotiers

in France, that every new tax creates a new ability in the subject to

bear it, and that each increase of public burdens increases

proportionably the industry of the people. This maxim is of such a

nature as is most likely to be extremely abused, and is so much the

more dangerous, as its truth cannot be altogether denied; but it must

be owned, when kept within certain bounds, to have some foundation in

reason and experience.

When a tax is laid upon commodities which are consumed by the common

people, the necessary consequence may seem to be that either the poor

must retrench something from their way of living, or raise their wages

so as to make the burden of the tax fall entirely upon the rich. But

there is a third consequence which very often follows upon taxes—viz.,

that the poor increase their industry, perform more work, and live as

well as before without demanding more for their labour. Where taxes

are moderate, are laid on gradually, and affect not the necessaries of

life, this consequence naturally follows; and it is certain that such

difficulties often serve to excite the industry of a people, and render

them more opulent and laborious than others who enjoy the greatest

advantages. For we may observe, as a parallel instance, that the most

commercial nations have not always possessed the greatest extent of

fertile land; but, on the contrary, that they have laboured under many

natural disadvantages. Tyre, Athens, Carthage, Rhodes, Genoa, Venice,

Holland are strong examples to this purpose; and in all history we

find only three instances of large and fertile countries which have

possessed much trade—the Netherlands, England, and France. The two

former seem to have been allured by the advantages of their maritime

situation, and the necessity they lay under of frequenting foreign

ports in order to procure what their own climate refused them; and as

to France, trade has come very late into the kingdom, and seems to

have been the effect of reflection and observation in an ingenious and

enterprising people, who remarked the immense riches acquired by such

of the neighbouring nations as cultivated navigation and commerce.

The places mentioned by Cicero as possessed of the greatest

commerce of his time are Alexandria, Colchos, Tyre, Sidon, Andros,

Cyprus, Pamphylia, Lycia, Rhodes, Chios, Byzantium, Lesbos, Smyrna,

Miletum, Coos. All these, except Alexandria, were either small islands

or narrow territories; and that city owed its trade entirely to the

happiness of its situation.

Since, therefore, some natural necessities or disadvantages may be

thought favourable to industries, why may not artificial burdens have

the same effect? Sir William Temple,​[26] we may observe, ascribes the

industry of the Dutch entirely to necessity, proceeding from their

natural disadvantages; and illustrates his doctrine by a very striking

comparison with Ireland, “where,” says he, “by the largeness and plenty

of the soil, and scarcity of people, all things necessary to life are

so cheap that an industrious man by two days’ labour may gain enough to

feed him the rest of the week. Which I take to be a very plain ground

of the laziness attributed to the people. For men naturally prefer ease

before labour, and will not take pains if they can live idle; though

when, by necessity, they have been inured to it, they cannot leave

it, being grown a custom necessary to their health, and to their very

entertainment. Nor perhaps is the change harder from constant ease

to labour than from constant labour to ease.” After which the author

proceeds to confirm his doctrine by enumerating as above the places

where trade has most flourished in ancient and modern times, and which

are commonly observed by such narrow, confined territories as beget a

necessity for industry.

It is always observed in years of scarcity, if it be not extreme, that

the poor labour more and really live better than in years of great

plenty, when they indulge themselves in idleness and riot. I have been

told by a considerable manufacturer that in the year 1740, when bread

and provisions of all kinds were very dear, his workmen not only made

a shift to live, but paid debts which they had contracted in

former years that were much more favourable and abundant.

This doctrine, therefore, with regard to taxes may be admitted to

some degree, but beware of the abuse. Exorbitant taxes, like extreme

necessity, destroy industry by producing despair; and even before they

reach this pitch they raise the wages of the labourer and manufacturer,

and heighten the price of all commodities. An attentive, disinterested

legislature will observe the point when the emolument ceases and the

prejudice begins; but as the contrary character is much more common,

it is to be feared that taxes all over Europe are multiplying to

such a degree as will entirely crush all art and industry; though

perhaps their first increase, together with circumstances, might have

contributed to the growth of these advantages.

The best taxes are such as are levied upon consumptions, especially

those of luxury, because such taxes are less felt by the people. They

seem, in some measure, voluntary, since a man may choose how far

he will use the commodity which is taxed: they are paid gradually

and insensibly, and being confounded with the natural price of the

commodity, they are scarcely perceived by the consumers. Their only

disadvantage is that they are expensive in the levying.

Taxes upon possessions are levied without expense, but have every other

disadvantage. Most states, however, are obliged to have recourse to

them, in order to supply the deficiencies of the other.

But the most pernicious of all taxes are those which are arbitrary.

They are commonly converted by their management into punishments on

industry; and also by their unavoidable inequality are more grievous

than by the real burden which they impose. It is surprising, therefore,

to see them have place among any civilized people.

In general, all poll-taxes, even when not arbitrary—which they commonly

are—may be esteemed dangerous; because it is so easy for the sovereign

to add a little more and a little more to the sum demanded, that these

taxes are apt to become altogether oppressive and intolerable. On the

other hand, a duty upon commodities checks itself, and a prince

will soon find that an increase of the impost is no increase of his

revenue. It is not easy, therefore, for a people to be altogether

ruined by such taxes.

Historians inform us that one of the chief causes of the destruction

of the Roman state was the alteration which Constantine introduced

into the finances, by substituting a universal poll-tax in lieu of

almost all the tithes, customs, and excises which formerly composed the

revenue of the empire. The people in all the provinces were so grinded

and oppressed by the publicans that they were glad to take refuge under

the conquering arms of the barbarians, whose dominion, as they had

fewer necessities and less art, was found preferable to the refined

tyranny of the Romans.

There is a prevailing opinion that all taxes, however levied, fall upon

the land at last. Such an opinion may be useful in Britain, by checking

the landed gentlemen, in whose hands our legislature is chiefly lodged,

and making them preserve great regard for trade and industry; but I

must confess that this principle, though first advanced by a celebrated

writer, has so little appearance of reason that were it not for his

authority it had never been received by anybody. Every man, to be sure,

is desirous of pushing off from himself the burden of any tax which

is imposed, and laying it upon others; but as every man has the same

inclination, and is upon the defensive, no set of men can be supposed

to prevail altogether in this contest. And why the landed gentleman

should be the victim of the whole, and should not be able to defend

himself as well as others are, I cannot readily imagine. All tradesmen,

indeed, would willingly prey upon him and divide him among them if they

could; but this inclination they always have, though no taxes were

levied; and the same methods by which he guards against the imposition

of tradesmen before taxes will serve him afterwards, and make them

share the burden with him. No labour in any commodities that are

exported can be very considerably raised in the price without losing

the foreign market; and as some part of almost every manufactory

is exported, this circumstance keeps the price of most species of

labour nearly the same after the imposition of taxes. I may add that it

has this effect upon the whole, for were any kind of labour paid beyond

its proportion all hands would flock to it, and would soon sink it to a

level with the rest.

I shall conclude this subject with observing that we have with

regard to taxes an instance of what frequently happens in political

institutions, that the consequence of things are diametrically opposite

to what we should expect on the first appearance. It is regarded as a

fundamental maxim of the Turkish Government that the Grand Seignior,

though absolute master of the lives and fortunes of each individual,

has no authority to impose a new tax; and every Ottoman prince who

has made such an attempt either has been obliged to retract, or has

found the fatal effects of his perseverance. One would imagine that

this prejudice or established opinion were the firmest barrier in the

world against oppression, yet it is certain that its effect is quite

contrary. The emperor, having no regular method of increasing his

revenue, must allow all the pashas and governors to oppress and abuse

the subjects, and these he squeezes after their return from their

government; whereas, if he could impose a new tax, like our European

princes, his interest would so far be united with that of his people

that he would immediately feel the bad effects of these disorderly

levies of money, and would find that a pound raised by general

imposition would have less pernicious effects than a shilling taken in

so unequal and arbitrary a manner.

OF PUBLIC CREDIT.

It appears to have been the common practice of antiquity to make

provision in times of peace for the necessities of war, and to hoard

up treasures beforehand as the instruments either of conquest or

defence, without trusting to extraordinary imposts, much less to

borrowing, in times of disorder and confusion. Besides the immense sums

above mentioned​[27] which were amassed by Athens, and by the Ptolemies

and other successors of Alexander, we learn from Plato that the frugal

Lacedemonians had also collected a great treasure; and Arrian and

Plutarch​[28] specify the riches which Alexander got possession of on

the conquest of Susa and Ecbatana, and which were reserved, some of

them, from the time of Cyrus. If I remember right, the Scripture also

mentions the treasure of Hezekiah and the Jewish princes, as profane

history does that of Philip and Perseus, kings of Macedon. The ancient

republics of Gaul had commonly large sums in reserve. Every one knows

the treasure seized in Rome by Julius Cæsar during the civil wars,

and we find afterwards that the wiser emperors, Augustus, Tiberius,

Vespasian, Severus, etc., always discovered the prudent foresight of

saving great sums against any public exigency.
