All genuine education comes about through experience.

The phrase "think for one's self" is a pleonasm. Unless one does it for one's self, it isn't thinking.

It science involves an intelligent and persistent endeavor to revise current beliefs so as to weed out what is erroneous, to add to their accuracy, and, above all, to give them such shape that the dependencies of the various facts upon one another may be as obvious as possible.

I should venture to assert that the most pervasive fallacy of philosophic thinking goes back to neglect of context.

Everything which bars freedom and fullness of communication sets up barriers that divide human beings into sets and cliques, into antagonistic sects and factions, and thereby undermines the democratic way of life.

An idea is a method of evading, circumventing or surmounting through reflection, obstacles that otherwise would have to be attacked by brute force.

The primary ineluctable facts of the birth and death of each one of the constituent members in a social group determine the necessity of education.
