I conclude that, while it is true that science cannot decide questions of value, that is because they cannot be intellectually decided at all, and lie outside the realm of truth and falsehood. Whatever knowledge is attainable, must be attained by scientific methods; and what science cannot discover, mankind cannot know.

The chicken noticed that the farmer came every day to feed it. It predicted that the farmer would continue to bring food every day. Inductivists think that the chicken had "extrapolated" its observations into a theory, and that each feeding time added justification to that theory. Then one day the farmer came and wrung the chicken's neck. This inductively justifies the conclusion that induction cannot justify any conclusion.

The examination system, and the fact that instruction is treated mainly as a training for a livelihood, leads the young to regard knowledge from a purely utilitarian point of view as the road to money, not as the gateway to wisdom.

From the height of their disillusionment they look down upon those whom they despise as simple souls. For my part I have no sympathy with this outlook.

Diversity is essential to happiness and in Utopia there is hardly any. This is a defect in all planned social systems.

The commonest objection to birth control is that it is against nature.
