Scientific principles and laws do not lie on the surface of nature. They are hidden, and must be wrested from nature by an active and elaborate technique of inquiry.

Inference is always an invasion of the unknown, a leap from the known.

An inanimate being is, of course, continuous with its surroundings; but the environing circumstances do not, save metaphorically, constitute an environment. For the inorganic being is not concerned in the influences which affect it.

We are a people of many races, many faiths, creeds, and religions. I do not think that the men who made the Constitution forbade the establishment of a State church because they were opposed to religion. They knew that the introduction of religious differences into American life would undermine the democratic foundations of this country. What holds for adults holds even more for children, sensitive and conscious of differences. I certainly hope that the Board of Education will think very, very seriously before it introduces this division and antagonism in our public schools.

In undeveloped social groups, we find very little formal teaching and training. Savage groups mainly rely for instilling needed dispositions into the young upon the same sort of association which keeps adults loyal to their group. They have no special devices, material, or institutions for teaching save in connection with initiation ceremonies by which the youth are inducted into full social membership. For the most part, they depend upon children learning the customs of the adults, acquiring their emotional set and stock of ideas, by sharing in what the elders are doing.

While the living thing may easily be crushed by superior force, it none the less tries to turn the energies which act upon it into means of its own further existence. If it cannot do so, it does not just split into smaller pieces (at least in the higher forms of life), but loses its identity as a living thing.
