The problem of restoring integration and co-operation between man's beliefs about the world in which he lives and his beliefs about values and purposes that should direct his conduct is the deepest problem modern life. It is the problem of any philosophy that is not isolated from life.

When "reality" is sought for at large, it is without intellectual import; at most the term carries the connotation of an agreeableemotional state.

a problem well put is half solved.

All of us have many habits of whose import we are quite unaware, since they were formed without our knowing what we were about. Consequently they possess us, rather than we them. They move us; they control us. Unless we become aware of what they accomplish, and pass judgment upon the worth of the result, we do not control them.

Perhaps the greatest of all pedagogical fallacies is the notion that a person learns only the particular thing he is studying at the time.

We can have facts without thinking but we cannot have thinking without facts.

We have three approaches at our disposal: the observation of nature, reflection, and experimentation. Observation serves to assemble the data, reflection to synthesise them and experimentation to test the results of the synthesis. The observation of nature must be assiduous, just as reflection must be profound, and experimentation accurate. These three approaches are rarely found together, which explains why creative geniuses are so rare.
