Thought is impossible without words.

If all meanings could be adequately expressed by words, the arts of painting and music would not exist.

As societies become more complex in structure and resources, the need of formal or intentional teaching and learning increases.

Just as the senses require sensible objects to stimulate them, so our powers of observation, recollection, and imagination do not work spontaneously, but are set in motion by the demands set up by current social occupations.

When words do not enter as factors into a shared situation, either overtly or imaginatively, they operate as pure physical stimuli, not as having a meaning or intellectual value. They set activity running in a given groove, but there is no accompanying conscious purpose or meaning.

Social engaged intellectuals must accept reality as they found it and shape it toward positive social goals, not stand aside in self-righteous isolation.

...the moment of passage from disturbance into harmony is that of intensest life.
