There is a constant trend in human affairs toward the perfectibility of mankind. This was plainly stated at the time of tile French Revolution and has been reasserted ever since that time, and with increasing plausibility.
Good heavens! what a foolish thing is this pretended perfectibility of the human race which is continually being dinned into our ears!
Democracy must stand or fall on a platform of possible human perfectibility. If human nature cannot be improved by institutions, democracy is at best a more than usually safe form of political organization . . . .

All history is man's efforts to realize ideals.
We are only now on the threshold of knowing the range of the educability of man-the perfectibility of man. We have never addressed ourselves to this problem before.

They are men and women who tend to believe that the human being is perfectible and social progress predictable, and that the instrument for effecting the two is reason; that truths are transitory and empirically determined; that equality is desirable and attainable through the action of state power; that social and individual differences, if they are not rational, are objectionable, and should be scientifically eliminated; that all people and societies strive to organize themselves upon a rationalist and scientific paradigm.
