The activity of the immature human being is simply played upon to secure habits which are useful. He is trained like an animal rather than educated like a human being.

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.

Religions have been universal in the sense that all the people we know anything about have had a religion. But the differences among them are so great and so shocking that any common element that can be extracted is meaningless....
