The general character and disposition of the Rationalist are, I think, not difficult to identify. At bottom he stands (he always stands) for independence of mind on all occasions, for thought free from obligation to any authority save the authority of 'reason'. His circumstances in the modern world have made him contentious: he is the enemy of authority, of prejudice, of the merely traditional, customary or habitual. His mental attitude is at once sceptical and optimistic: sceptical, because there is no opinion, no habit, no belief, nothing so firmly rooted or so widely held that he hesitates to question it and to judge it by what he calls his 'reason'; optimistic, because the Rationalist never doubts the power of his 'reason' (when properly applied) to determine the worth of a thing, the truth of an opinion or the propriety of an action.
By one road or another, by conviction, by its supposed inevitability, by its alleged success, or even quite unreflectively, almost all politics today have become Rationalist or near-Rationalist.
