indirect correspondence with its soil and climate. Many obviously fabulous dogmas, like those of religion, might for ever dominate the most active minds, except for one circumstance. In the jungle one tree strangles another, and luxuriance itself is murderous. So is luxuriance in the human mind. What kills spontaneous fictions, what recalls the impassioned fancy from its improvisation, is the angry voice of some contrary fancy. Nature, silently making fools of us all our lives, never would bring us to our senses; but the maddest assertions of the mind may do so, when they challenge one another. Criticism arises out of the conflict of dogmas.
May I escape this predicament and criticise without a dogmatic criterion? Hardly; for though the criticism may be expressed hypothetically, as for instance in saying that if any child knew his own father he would be a wise child, yet the point on which doubt is thrown is a point of fact, and that there are fathers and children is assumed dogmatically. If not, however obscure the essential relation between fathers and children might be ideally, no one could be wise or foolish in assigning it in any particular instance, since no such terms would exist in nature at all. Scepticism is a suspicion of error about facts, and to suspect error about facts is to share the enterprise of knowledge, in which facts are presupposed and error is possible. The sceptic thinks himself shrewd, and often is so; his intellect, like the intellect he criticises, may have some inkling of the true hang and connection of things; he may have pierced to a truth of nature behind current illusions. Since his criticism may thus be true and his doubt well grounded, they are certainly assertions; and if he is sincerely a sceptic, they are assertions which he is ready to maintain stoutly. Scepticism is accordingly a form of belief. Dogma cannot be abandoned; it can only
