424 question be not the fact, what has hitherto prevented scepticism from putting a final extinguisher on Reid's appeal by proving that no such belief exists? A very sufficient reason has prevented scepticism from doing this, from explicitly extinguishing the appeal. There is a division of labour in speculation as well as in other pursuits. It is the sceptic's business simply to deny the existence of the belief: it is no part of his business to exhibit the grounds of his denial. We have explained these grounds; but were the sceptic to do this, he would be travelling out of his vocation. Observe how the case stands. The reason why matter per se is not and cannot be believed in, is because it is impossible for thought to disengage matter from perception, and consequently it is impossible for thought to believe in the disengaged existence of matter. The matter to be believed in is not disengaged from the perception, consequently it cannot be believed to be disengaged from the perception. But unless it be believed to be disengaged from the perception, it cannot be believed to exist per se. In short, as we have already said, the impossibility of complying with the condition of the belief is the ground on which the sceptic denies the existence of the belief. But the sceptic is himself debarred from producing these grounds. Why? Because their exhibition would be tantamount to a rejection of the principle which he has accepted at the hands of the orthodox and dogmatic psychologist. That principle is the analysis so often spoken of—
