"If a philosophic theory is once ruled out of court, no one can tell when it will appear again." — Morris Raphael Cohen

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.

Lastly, literature and philosophy both allow past idols to be resurrected with a frequency which would be truly distressing to a sober scientist.

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.

The method of exposition which philosophers have adopted leads many to suppose that they are simply inquiries, that they have no interest in the conclusions at which they arrive, and that their primary concern is to follow their premises to their logical conclusions.
