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.

The intimation never wholly deserts us that there is, in the unformed activities of childhood and youth, the possibilities of a better life for the community as well as for individuals here and there. This dim sense is the ground of our abiding idealization of childhood.
