A fourth-grade reader may be a sixth-grade mathematician. The grade is an administrative device which does violence to the nature of the developmental process.

No theory changes what it is a theory about. Nothing is changed because we look at it, talk about it, or analyze it in a new way. Keats drank confusion to Newton for analyzing the rainbow, but the rainbow remained as beautiful as ever and became for many even more beautiful. Man has not changed because we look at him, talk about him, and analyze him scientifically. ... What does change is our chance of doing something about the subject of a theory. Newton's analysis of the light in a rainbow was a step in the direction of the laser.

Many social practices essential to the welfare of the species involve the control of one person by another, and no one can suppress them who has any concern for human achievements

Punitive measures whether administered by police, teachers, spouses or parents have well known standard effects: (1) escape-education has its own name for that: truancy, (2) counterattack-vandalism on schools and attacks on teachers, (3) apathy-a sullen do-nothing withdrawal. The more violent the punishment, the more serious the by-products.

The evolution of cultures appears to follow the pattern of the evolution of species. The many different forms of culture which arise correspond to the "mutations" of genetic theory. Some forms prove to be effective under prevailing circumstances and others not, and the perpetuation of the culture is determined accordingly.

Fame is also won at the expense of others. Even the well-deserved honors of the scientist or man of learning are unfair to many persons of equal achievements who get none. When one man gets a place in the sun, the others are put in a denser shade. From the point of view of the whole group there's no gain whatsoever, and perhaps a loss.

A scientist may not be sure of the answer, but he's often sure he can find one. And that's a condition which is clearly not enjoyed by philosophy.
