CHAPTER VII.
OUTLINE OF THE HISTORY OF THE ENGLISH INTELLECT FROM THE MIDDLE OF THE SIXTEENTH TO THE END OF THE EIGHTEENTH CENTURY.
It is difficult for an ordinary reader, living in the middle of the nineteenth century, to understand, that only three hundred years before he was born, the public mind was in the benighted state disclosed in the preceding chapter. It is still more difficult for him to understand that the darkness was shared not merely by men of an average education, but by men of considerable ability, men in every respect among the foremost of their age. A reader of this sort may satisfy himself that the evidence is indisputable; he may verify the statements I have brought forward, and admit that there is no possible doubt about them; but even then he will find it hard to conceive that there ever was a state of society in which such miserable absurdities were welcomed as sober and important truths, and were supposed to form an essential part of the general stock of European knowledge.
But a more careful examination will do much to dissipate this natural astonishment. In point of fact, so far from wondering that such things were believed, the wonder would have been if they were rejected. For in those times, as in all others, every thing was of a piece. Not only in historical literature, but in all kinds of literature, on every subject—in science, in religion, in legislation—the presiding principle was a blind and unhesitating credulity. The more the history of Europe anterior to the seventeenth century is studied, the more completely will this fact be verified. Now and then a great man arose, who had his doubts respecting the universal belief; who whispered a suspicion as to the existence of giants thirty feet high, of dragons with wings, and of armies flying through the air; who thought that astrology might be a cheat, and necromancy a bubble; and who even went so far as to raise a question respecting the propriety of drowning every witch and burning every heretic. A few such men there undoubtedly were; but they were despised as mere theorists, idle visionaries, who, unacquainted with the practice of life, arrogantly opposed their own reason to the wisdom of their ancestors. In the state of society in which they were born, it was impossible that they should make any permanent impression. Indeed, they had enough to do to look to themselves, and provide for their own security; for, until the latter part of the sixteenth century, there was no country in which a man was not in great personal peril if he expressed open doubts respecting the belief of his contemporaries.
Yet it is evident, that until doubt began, progress was impossible. For, as we have clearly seen, the advance of civilization solely depends on the acquisitions made by the human intellect, and on the extent to which those acquisitions are diffused. But men who are perfectly satisfied with their own knowledge, will never attempt to increase it. Men who are perfectly convinced of the accuracy of their opinions, will never take the pains of examining the basis on which they are built. They look always with wonder, and often with horror, on views contrary to those which they inherited from their fathers; and while they are in this state of mind, it is impossible that they should receive any new truth which interferes with their foregone conclusions.
On this account it is, that although the acquisition of fresh knowledge is the necessary precursor of every step in social progress, such acquisition must itself be preceded by a love of inquiry, and therefore by a spirit of doubt; because without doubt there will be no inquiry, and without inquiry there will be no knowledge. For knowledge is not an inert and passive principle, which comes to us whether we will or no; but it must be sought before it can be won; it is the product of great labour and therefore of great sacrifice. And it is absurd to suppose that men will incur the labour, and make the sacrifice, for subjects respecting which they are already perfectly content. They who do not feel the darkness, will never look for the light. If on any point we have attained to certainty, we make no further inquiry on that point; because inquiry would be useless, or perhaps dangerous. The doubt must intervene, before the investigation can begin. Here, then, we have the act of doubting as the originator, or, at all events, the necessary antecedent, of all progress. Here we have that scepticism, the very name of which is an abomination to the ignorant; because it disturbs their lazy and complacent minds; because it troubles their cherished superstitions; because it imposes on them the fatigue of inquiry; and because it rouses even sluggish understandings to ask if things are as they are commonly supposed, and if all is really true which they from their childhood have been taught to believe.
The more we examine this great principle of scepticism, the more distinctly shall we see the immense part it has played in the progress of European civilization. To state in general terms, what in this Introduction will be fully proved, it may be said, that to scepticism we owe that spirit of inquiry, which, during the last two centuries, has gradually encroached on every possible subject; has reformed every department of practical and speculative knowledge; has weakened the authority of the privileged classes, and thus placed liberty on a surer foundation; has chastized the despotism of princes; has restrained the arrogance of the nobles; and has even diminished the prejudices of the clergy. In a word, it is this which has remedied the three fundamental errors of the olden time: errors which made the people, in politics too confiding; in science too credulous; in religion too intolerant.
