CHAPTER III. CARTESIANISM

If we are to draw any useful lines of demarcation in the continuous flux

of history we must neglect anticipations and announcements, and we need

not scruple to say that, in the realm of knowledge and thought, modern

history begins in the seventeenth century. Ubiquitous rebellion against

tradition, a new standard of clear and precise thought which affects

even literary expression, a flow of mathematical and physical

discoveries so rapid that ten years added more to the sum of knowledge

than all that had been added since the days of Archimedes, the

introduction of organised co-operation to increase knowledge by the

institution of the Royal Society at London, the Academy of Sciences at

Paris, Observatories--realising Bacon's Atlantic dream--characterise the

opening of a new era.

For the ideas with which we are concerned, the seventeenth century

centres round Descartes, whom an English admirer described as "the grand

secretary of Nature." [Footnote: Joseph Glanvill, Vanity of Dogmatising,

p. 211, 64] Though his brilliant mathematical discoveries were the sole

permanent contribution he made to knowledge, though his metaphysical and

physical systems are only of historical interest, his genius exercised

a more extensive and transforming influence on the future development of

thought than any other man of his century.

Cartesianism affirmed the two positive axioms of the supremacy of

reason, and the invariability of the laws of nature; and its instrument

was a new rigorous analytical method, which was applicable to history as

well as to physical knowledge. The axioms had destructive corollaries.

The immutability of the processes of nature collided with the theory

of an active Providence. The supremacy of reason shook the thrones from

which authority and tradition had tyrannised over the brains of men.

Cartesianism was equivalent to a declaration of the Independence of Man.

It was in the atmosphere of the Cartesian spirit that a theory of

Progress was to take shape.

1.

Let us look back. We saw that all the remarks of philosophers prior to

the seventeenth century, which have been claimed as enunciations of the

idea of Progress, amount merely to recognitions of the obvious fact that

in the course of the past history of men there have been advances

and improvements in knowledge and arts, or that we may look for some

improvements in the future. There is not one of them that adumbrates

a theory that can be called a theory of Progress. We have seen several

reasons why the idea could not emerge in the ancient or in the

Middle Ages. Nor could it have easily appeared in the period of the

Renaissance. Certain preliminary conditions were required, and these

were not fulfilled till the seventeenth century. So long as men believed

that the Greeks and Romans had attained, in the best days of their

civilisation, to an intellectual plane which posterity could never

hope to reach, so long as the authority of their thinkers was set up as

unimpeachable, a theory of degeneration held the field, which excluded

a theory of Progress. It was the work of Bacon and Descartes to liberate

science and philosophy from the yoke of that authority; and at the same

time, as we shall see, the rebellion began to spread to other fields.

Another condition for the organisation of a theory of Progress was a

frank recognition of the value of mundane life and the subservience of

knowledge to human needs. The secular spirit of the Renaissance prepared

the world for this new valuation, which was formulated by Bacon, and has

developed into modern utilitarianism.

There was yet a third preliminary condition. There can be no certainty

that knowledge will continually progress until science has been

placed on sure foundations. And science does not rest for us on sure

foundations unless the invariability of the laws of nature is admitted.

If we do not accept this hypothesis, if we consider it possible that the

uniformities of the natural world may be changed from time to time, we

have no guarantee that science can progress indefinitely. The philosophy

of Descartes established this principle, which is the palladium of

science; and thus the third preliminary condition was fulfilled.

2.

During the Renaissance period the authority of the Greeks and Romans

had been supreme in the realm of thought, and in the interest of

further free development it was necessary that this authority should

be weakened. Bacon and others had begun the movement to break down this

tyranny, but the influence of Descartes was weightier and more decisive,

and his attitude was more uncompromising. He had none of Bacon's

reverence for classical literature; he was proud of having forgotten the

Greek which he had learned as a boy. The inspiration of his work was the

idea of breaking sharply and completely with the past, and constructing

a system which borrows nothing from the dead. He looked forward to an

advancement of knowledge in the future, on the basis of his own method

and his own discoveries, [Footnote: Cf. for instance his remarks on

medicine, at the end of the Discours de la methode.] and he conceived

that this intellectual advance would have far-reaching effects on the

condition of mankind. The first title he had proposed to give to his

Discourse on Method was "The Project of a Universal Science which can

elevate our Nature to its highest degree of Perfection." He regarded

moral and material improvement as depending on philosophy and science.

The justification of an independent attitude towards antiquity, on

the ground that the world is now older and more mature, was becoming a

current view. [Footnote: Descartes wrote: Non est quod antiquis multum

tribuamus propter antiquitatem, sed nos potius iis seniores dicendi. Jam

enim senior est mundus quam tune majoremque habemus rerum experientiam.

(A fragment quoted by Baillet, Vie de Descartes, viii. 10.) Passages

to the same effect occur in Malebranche, Arnauld, and Nicole. (See

Bouillier, Histoire de la philosophie cartesienne, i. 482-3.)

A passage in La Mothe Le Vayer's essay Sur l'opiniatrete in Orasius

Tubero (ii. 218) is in point, if, as seems probable, the date of that

work is 1632-33. "Some defer to the ancients and allow themselves to be

led by them like children; others hold that the ancients lived in the

youth of the world, and it is those who live to-day who are really the

ancients, and consequently ought to carry most weight." See Rigault,

Histoire de la querelle des Anciens et des Modernes, p. 52.

The passage of Pascal occurs in the Fragment d'un traite du vide, not

published till 1779 (now included in the Pensees, Premiere Partie, Art.

I), and therefore without influence on the origination of the theory of

progress. It has been pointed out that Guillaume Colletet had in 1636

expressed a similar view (Brunetiere, Etudes critiques, v. 185-6).]

Descartes expressed it like Bacon, and it was taken up and repeated

by many whom Descartes influenced. Pascal, who till 1654 was a man of

science and a convert to Cartesian ideas, put it in a striking way.

The whole sequence of men (he says) during so many centuries should

be considered as a single man, continually existing and continually

learning. At each stage of his life this universal man profited by the

knowledge he had acquired in the preceding stages, and he is now in his

old age. This is a fuller, and probably an independent, development of

the comparison of the race to an individual which we found in Bacon. It

occurs in a fragment which remained unpublished for more than a hundred

years, and is often quoted as a recognition, not of a general progress

of man, but of a progress in human knowledge.

To those who reproached Descartes with disrespect towards ancient

thinkers he might have replied that, in repudiating their authority, he

was really paying them the compliment of imitation and acting far more

in their own spirit than those who slavishly followed them. Pascal saw

this point. "What can be more unjust," he wrote, "than to treat our

ancients with greater consideration than they showed towards their own

predecessors, and to have for them this incredible respect which they

deserve from us only because they entertained no such regard for

those who had the same advantage (of antiquity) over them?" [Footnote:

Pensees, ib.]

At the same time Pascal recognised that we are indebted to the ancients

for our very superiority to them in the extent of our knowledge. "They

reached a certain point, and the slightest effort enables us to mount

higher; so that we find ourselves on a loftier plane with less trouble

and less glory." The attitude of Descartes was very different. Aspiring

to begin ab integro and reform the foundations of knowledge, he ignored

or made little of what had been achieved in the past. He attempted

to cut the threads of continuity as with the shears of Atropos. This

illusion [Footnote: He may be reproached himself with scholasticism in

his metaphysical reasoning.] hindered him from stating a doctrine of

the progress of knowledge as otherwise he might have done. For any such

doctrine must take account of the past as well as of the future.

But a theory of progress was to grow out of his philosophy, though he

did not construct it. It was to be developed by men who were imbued with

the Cartesian spirit.

3.

The theological world in France was at first divided on the question

whether the system of Descartes could be reconciled with orthodoxy

or not. The Jesuits said no, the Fathers of the Oratory said yes.

The Jansenists of Port Royal were enthusiastic Cartesians. Yet it was

probably the influence of the great spiritual force of Jansenism that

did most to check the immediate spread of Cartesian ideas. It was

preponderant in France for fifty years. The date of the Discourse of

Method is 1637. The Augustinus of Jansenius was published in 1640, and

in 1643 Arnauld's Frequent Communion made Jansenism a popular power.

The Jansenist movement was in France in some measure what the Puritan

movement was in England, and it caught hold of serious minds in much

the same way. The Jesuits had undertaken the task of making Christianity

easy, of finding a compromise between worldliness and religion, and they

flooded the world with a casuistic literature designed for this purpose.

Ex opinionum varietate jugum Christi suavius deportatur. The doctrine of

Jansenius was directed against this corruption of faith and morals.

He maintained that there can be no compromise with the world; that

casuistry is incompatible with morality; that man is naturally corrupt;

and that in his most virtuous acts some corruption is present.

Now the significance of these two forces--the stern ideal of the

Jansenists and the casuistry of the Jesuit teachers--is that they both

attempted to meet, by opposed methods, the wave of libertine thought and

conduct which is a noticeable feature in the history of French society

from the reign of Henry IV. to that of Louis XV. [Footnote: For the

prevalence of "libertine" thought in France at the beginning of the

seventeenth century see the work of the Pere Garasse, La Doctrine

curieuse des beaux esprits de ce temps ou pretendus tels, etc. (1623).

Cp. also Brunetiere's illuminating study, "Jansenistes et Cartesiens"

in Etudes critiques, 4me serie.] This libertinism had its philosophy, a

sort of philosophy of nature, of which the most brilliant exponents

were Rabelais and Moliere. The maxim, "Be true to nature," was evidently

opposed sharply to the principles of the Christian religion, and it was

associated with sceptical views which prevailed widely in France from

the early years of the seventeenth century. The Jesuits sought to make

terms by saying virtually: "Our religious principles and your philosophy

of nature are not after all so incompatible in practice. When it comes

to the application of principles, opinions differ. Theology is as

elastic as you like. Do not abandon your religion on the ground that her

yoke is hard." Jansenius and his followers, on the other hand, fought

uncompromisingly with the licentious spirit of the time, maintaining

the austerest dogmas and denouncing any compromise or condescension. And

their doctrine had a wonderful success, and penetrated everywhere. Few

of the great literary men of the reign of Louis XIV. escaped it. Its

influence can be traced in the Maximes of La Rochefoucauld and the

Caracteres of La Bruyere. It was through its influence that Moliere

found it difficult to get some of his plays staged. It explains the fact

that the court of Louis XIV., however corrupt, was decorous compared

with the courts of Henry IV. and Louis XV.; a severe standard was set

up, if it was not observed.

The genius of Pascal made the fortunes of Jansenism. He outlived his

Cartesianism and became its most influential spokesman. His

Provinciales (1656) rendered abstruse questions of theology more or less

intelligible, and invited the general public to pronounce an opinion on

them. His lucid exposition interested every one in the abstruse problem,

Is man's freedom such as not to render grace superfluous? But Pascal

perceived that casuistry was not the only enemy that menaced the true

spirit of religion for which Jansenism stood. He came to realise that

Cartesianism, to which he was at first drawn, was profoundly opposed to

the fundamental views of Christianity. His Pensees are the fragments of

a work which he designed in defence of religion, and it is easy to see

that this defence was to be specially directed against the ideas of

Descartes.

Pascal was perfectly right about the Cartesian conception of the

Universe, though Descartes might pretend to mitigate its tendencies, and

his fervent disciple, Malebranche, might attempt to prove that it was

more or less reconcilable with orthodox doctrine. We need not trouble

about the special metaphysical tenets of Descartes. The two axioms

which he launched upon the world--the supremacy of reason, and the

invariability of natural laws--struck directly at the foundations of

orthodoxy. Pascal was attacking Cartesianism when he made his memorable

attempt to discredit the authority of reason, by showing that it is

feeble and deceptive. It was a natural consequence of his changed

attitude that he should speak (in the Pensees) in a much less confident

tone about the march of science than he had spoken in the passage which

I quoted above. And it was natural that he should be pessimistic about

social improvement, and that, keeping his eyes fixed on his central fact

that Christianity is the goal of history, he should take only a slight

and subsidiary interest in amelioration.

The preponderant influence of Jansenism only began to wane during the

last twenty years of the seventeenth century, and till then it seems

to have been successful in counteracting the diffusion of the Cartesian

ideas. Cartesianism begins to become active and powerful when Jansenism

is beginning to decline. And it is just then that the idea of Progress

begins definitely to emerge. The atmosphere in France was favourable for

its reception.

4.

The Cartesian mechanical theory of the world and the doctrine of

invariable law, carried to a logical conclusion, excluded the doctrine

of Providence. This doctrine was already in serious danger. Perhaps

no article of faith was more insistently attacked by sceptics in the

seventeenth century, and none was more vital. The undermining of the

theory of Providence is very intimately connected with our subject;

for it was just the theory of an active Providence that the theory of

Progress was to replace; and it was not till men felt independent of

Providence that they could organise a theory of Progress.

Bossuet was convinced that the question of Providence was the most

serious and pressing among all the questions of the day that were at

issue between orthodox and heretical thinkers. Brunetiere, his fervent

admirer, has named him the theologian of Providence, and has shown that

in all his writings this doctrine is a leading note. It is sounded

in his early sermons in the fifties, and it is the theme of his most

ambitious work, the Discourse on Universal History, which appeared

in 1681. [Footnote; It has been shown that on one hand he controverts

Spinoza's Tractatus theologico-politicus, and on the other the dangerous

methods of Richard Simon, one of the precursors of modern biblical

criticism. Brunetiere, op. cit. 74-85.] This book, which has received

high praise from those who most heartily dissent from its conclusions,

is in its main issue a restatement of the view of history which

Augustine had worked out in his memorable book. The whole course of

human experience has been guided by Providence for the sake of the

Church; that is, for the sake of the Church to which Bossuet belonged.

Regarded as a philosophy of history the Discourse may seem little more

than the theory of the De Civitate Dei brought up to date; but this is

its least important aspect. We shall fail to understand it unless we

recognise that it was a pragmatical, opportune work, designed for the

needs of the time, and with express references to current tendencies of

thought.

One main motive of Bossuet in his lifelong concern for Providence

was his conviction that the doctrine was the most powerful check on

immorality, and that to deny it was to remove the strongest restraint

on the evil side of human nature. There is no doubt that the free-living

people of the time welcomed the arguments which called Providence in

question, and Bossuet believed that to champion Providence was the

most efficient means of opposing the libertine tendencies of his day.

"Nothing," he declared in one of his sermons (1662), "has appeared

more insufferable to the arrogance of libertines than to see themselves

continually under the observation of this ever-watchful eye of

Providence. They have felt it as an importunate compulsion to recognise

that there is in Heaven a superior force which governs all our movements

and chastises our loose actions with a severe authority. They have

wished to shake off the yoke of this Providence, in order to maintain,

in independence, an unteachable liberty which moves them to live at

their own fancy, without fear, discipline, or restraint." [Passage from

Bossuet, quoted by Brunetiere, op. cit. 58.] Bossuet was thus working in

the same cause as the Jansenists.

He had himself come under the influence of Descartes, whose work he

always regarded with the deepest respect. The cautiousness of the master

had done much to disguise the insidious dangers of his thought, and it

was in the hands of those disciples who developed his system and sought

to reconcile it at all points with orthodoxy that his ideas displayed

their true nature. Malebranche's philosophy revealed the incompatibility

of Providence--in the ordinary acceptation--with immutable natural laws.

If the Deity acts upon the world, as Malebranche maintained, only by

means of general laws, His freedom is abolished, His omnipotence is

endangered, He is subject to a sort of fatality. What will become of the

Christian belief in the value of prayers, if God cannot adapt or modify,

on any given occasion, the general order of nature to the needs of human

beings? These are some of the arguments which we find in a treatise

composed by Fenelon, with the assistance of Bossuet, to demonstrate

that the doctrine of Malebranche is inconsistent with piety and orthodox

religion. They were right. Cartesianism was too strong a wine to

be decanted into old bottles. [Footnote: Fenelon's Refutation of

Malebranche's Traite de la nature et de la grace was not published till

1820. This work of Malebranche also provoked a controversy with Arnauld,

who urged similar arguments.]

Malebranche's doctrine of what he calls divine Providence was closely

connected with his philosophical optimism. It enabled him to maintain

the perfection of the universe. Admitting the obvious truth that the

world exhibits many imperfections, and allowing that the Creator

could have produced a better result if he had employed other means,

Malebranche argued that, in judging the world, we must take into account

not only the result but the methods by which it has been produced. It is

the best world, he asserts, that could be framed by general and simple

methods; and general and simple methods are the most perfect, and alone

worthy of the Creator. Therefore, if we take the methods and the

result together, a more perfect world is impossible. The argument was

ingenious, though full of assumptions, but it was one which could only

satisfy a philosopher. It is little consolation to creatures suffering

from the actual imperfections of the system into which they are born to

be told that the world might have been free from those defects, only in

that case they would not have the satisfaction of knowing that it was

created and conducted on theoretically superior principles.

Though Malebranche's conception was only a metaphysical theory,

metaphysical theories have usually their pragmatic aspects; and the

theory that the universe is as perfect as it could be marks a stage

in the growth of intellectual optimism which we can trace from the

sixteenth century. It was a view which could appeal to the educated

public in France, for it harmonised with the general spirit of

self-complacency and hopefulness which prevailed among the higher

classes of society in the reign of Louis XIV. For them the conditions

of life under the new despotism had become far more agreeable than in

previous ages, and it was in a spirit of optimism that they devoted

themselves to the enjoyment of luxury and elegance. The experience of

what the royal authority could achieve encouraged men to imagine that

one enlightened will, with a centralised administration at its command,

might accomplish endless improvements in civilisation. There was no age

had ever been more glorious, no age more agreeable to live in.

The world had begun to abandon the theory of corruption, degeneration,

and decay.

Some years later the optimistic theory of the perfection of the universe

found an abler exponent in Leibnitz, whom Diderot calls the father of

optimism. [Footnote: See particularly Monadologie, ad fin. published

posthumously in German 1720, in Latin 1728; Theodicee, Section 341

(1710); and the paper, De rerum originatione radicali, written in 1697,

but not published till 1840 (Opera philosophica, ed. Erdmann, p. 147

sqq).] The Creator, before He acted, had considered all possible worlds,

and had chosen the best. He might have chosen one in which humanity

would have been better and happier, but that would not have been

the best possible, for He had to consider the interests of the whole

universe, of which the earth with humanity is only an insignificant

part. The evils and imperfections of our small world are negligible

in comparison with the happiness and perfection of the whole cosmos.

Leibnitz, whose theory is deduced from the abstract proposition that

the Creator is perfect, does not say that now or at any given moment

the universe is as perfect as it could be; its merit lies in its

potentialities; it will develop towards perfection throughout infinite

time.

The optimism of Leibnitz therefore concerns the universe as a whole, not

the earth, and would obviously be quite consistent with a pessimistic

view of the destinies of humanity. He does indeed believe that it would

be impossible to improve the universal order, "not only for the

whole, but for ourselves in particular," and incidentally he notes

the possibility that "in the course of time the human race may reach a

greater perfection than we can imagine at present." But the significance

of his speculation and that of Malebranche lies in the fact that the old

theories of degeneration are definitely abandoned.
