CHAPTER VIII.

"If, as the result of your learning and meditation, you chanced to

discover some important truth, not only formerly unknown, but quite

unlooked for, and even antagonistic to the opinions of the day, you

must not anticipate in your lifetime any peculiar commendation for this

discovery. You will gain no esteem, even from the wise (except perhaps

from a very few), until by frequent and varied reiteration of these

truths the ears of men have become accustomed to their sound; then

only, after a long time, the intellect begins to receive them.

"For no truth contrary to current opinion, even though demonstrable

with almost geometrical certitude, can ever, unless capable of material

proof, be suddenly established. Time, custom, and example alone are

able to give it a solid foundation. Men accustom themselves to belief,

as to everything else; indeed they generally believe from habit, and

not from any sentiment of conviction within their minds. At length

it happens that the once-questioned truth is taught to children, and

is universally accepted. People are then astonished that it was ever

unknown to them, and they ridicule their ancestors and contemporaries

for the ignorance and obstinacy they manifested in opposing it. The

greater and more important the new truths, so much the greater will

be the difficulty of procuring acceptance for them; since they will

overthrow a proportionately large number of opinions hitherto rooted

in the minds of men. For even acute and practised intellects do not

easily enter into the spirit of reasonings which demonstrate new truths

that exceed the limits of their own knowledge; especially when these

are opposed to beliefs long established within them. Descartes, in

his geometrical discoveries, was understood by but very few of his

contemporaries. It was the same with Newton. Indeed, the condition of

men pre-eminent in knowledge is somewhat similar to that of literary

men, and 'savants' who live in places innocent of learning. The latter

are not deservedly esteemed by their neighbours; the former fail to be

duly appreciated by their contemporaries. Both are often despised for

their difference in manner of life and opinions from other men, who

neither do justice to their ability nor to the writings they put forth

in proof of it.

"There is no doubt that the human race makes continual progress in

knowledge. As a body, its march is slow and measured; but it includes

certain great and remarkable minds which, having devoted themselves

to speculation about the sensible or intelligible phenomena of the

universe, and the pursuit of truths, travel, nay sometimes flash, to

their conclusions in an immeasurably short space of time. And the rapid

progress of these intellects stimulates other men, who hasten their

foot-steps so as to reach, later on, the place where these superior

beings rested. But not until the lapse of a century or more do they

attain to the knowledge possessed by an extraordinary intellect of this

kind.

"It is ordinarily believed that human knowledge owes most of its

progress to these supreme intellects, which arise from time to time,

like miracles of nature.[1] I, on the contrary, think that it owes

more to men of common powers than to those who are exceptionally

endowed. Suppose a case, in which one of the latter, having rivalled

his contemporaries in knowledge, advances independently, and takes a

lead of, say ten paces. Most other men, far from feeling disposed

to follow him, regard his progress in silence, or else ridicule it.

Meanwhile, a number of moderately clever men, partly aided perhaps by

the ideas and discoveries of the genius, but principally through their

own endeavours, conjointly advance one step. The masses unhesitatingly

follow them, being attracted by the not inordinate novelty, and also by

the number of those who are its authors. In process of time, thanks to

the exertions of these men, the tenth step is accomplished; and thus

the opinions of the genius are universally received throughout the

civilised world. But their originator, dead long ago, only acquires a

late and unseasonable reputation. This is due partly to the fact that

he is forgotten, or to the low esteem in which he was held when living;

added to which men are conscious that they do not owe their knowledge

to him, and that they are already his equals in erudition, and will

soon surpass him, if they have not done so already. They are also his

superiors, in that time has enabled them to demonstrate and affirm

truths that he only imagined, to prove his conjectures, and give better

form and order to his inventions, almost, as it were, maturing them.

Perchance, after a time, some student engaged in historical research

may justly appraise the influence of this genius, and may announce him

to his countrymen with great _Èclat_; but the fame that may ensue from

this will soon give way to renewed oblivion.

"The progress of human knowledge, like a falling weight, increases

momentarily in its speed; none the less very rarely men of a generation

change their beliefs or recognise their errors, so as to believe at one

time the opposite of what they previously believed. Each generation

prepares the way for its successor to know and believe many things

contrary to its own knowledge and belief. But most men are as little

conscious of the increasing development of their knowledge, and the

inevitable mutation of their beliefs, as they are sensible of the

perpetual motion of the earth. And a man never alters his opinions so

as to be conscious of the alteration. But were he suddenly to embrace

an opinion totally discordant with his old beliefs, he could not fail

to perceive the change. It may therefore be said, that ordinarily no

truths, except such as are determinable by the senses, will be believed

by the contemporaries of their discoverer."

generative, constitutive mind should come first; and then that the

patient and collective mind should follow, and elaborate the pregnant

queries and illumining guesses of the former,--S. T. Coleridge, _Table

Talk_, Oct. 8, 1830.]
