There is one respect, however, in which there is justification for saying that the liberal occupies a position midway between the socialist and the conservative: he is as far from the crude rationalism of the socialist, who wants to reconstruct all social institutions according to a pattern prescribed by his individual reason, as from the mysticism to which the conservative so frequently has to resort. What I have described as the liberal position shares with conservatism a distrust of reason to the extent that the liberal is very much aware that we do not know all the answers and that he is not sure that the answers he has are certainly the right ones or even that we can find all the answers. He also does not disdain to seek assistance from whatever non-rational institutions or habits have proved their worth. The liberal differs from the conservative in his willingness to face this ignorance and to admit how little we know, without claiming the authority of supernatural sources of knowledge where his reason fails him. It has to be admitted that in some respects the liberal is fundamentally a skeptic—but it seems to require a certain degree of diffidence to let others seek their happiness in their own fashion and to adhere consistently to that tolerance which is an essential characteristic of liberalism.
There is no reason why this need mean an absence of religious belief on the part of the liberal. Unlike the rationalism of the French Revolution, true liberalism has no quarrel with religion, and I can only deplore the militant and essentially illiberal antireligionism which animated so much of nineteenth-century Continental liberalism. That this is not essential to liberalism is clearly shown by its English ancestors, the Old Whigs, who, if anything, were much too closely allied with a particular religious belief. What distinguishes the liberal from the conservative here is that, however profound his own spiritual beliefs, he will never regard himself as entitled to impose them on others and that for him the spiritual and the temporal are different spheres which ought not to be confused.
