Liberalism regards life as an adventure in which we must take risks in new situation, in which there is no guarantee that the new will always be the good or the true, in which progress is a precarious achievement rather than inevitability.
The picture which the philosopher draws of the world is surely not one in which every stroke is necessitated by pure logic.
A creative element is surely present in all great systems, and it does not seem possible that all sympathy or fundamental attitudes of will can be entirely eliminated from any human philosophy.
It is not impossible to think that the minds of philosophers sometimes act like those of other mortals, and that, having once been determined by diverse circumstances to adopt certain views, they then look for and naturally find reasons to justify these views.
In thus pointing out certain respects in which philosophy resembles literature more than science, I do not mean, of course, to imply that it would be well for philosophy if it ceased to aim at scientific rigor.
It has generally been assumed that of two opposing systems of philosophy, e.g., realism and idealism, one only can be true and one must be false; and so philosophers have been hopelessly divided on the question, which is the true one.
Liberalism is an attitude rather than a set of dogmas – an attitude that insists upon questioning all plausible and self-evident propositions, seeking not to reject them but to find out what evidence there is to support them rather than their possible alternatives.
To be sure, the vast majority of people who are untrained can accept the results of science only on authority.
Let philosophy resolutely aim to be as scientific as possible, but let her not forget her strong kinship with literature.
Literature and philosophy both allow past idols to be resurrected with a frequency which would be truly distressing to a sober scientist.
