Religion is what the individual does with his own solitariness. Thus religion is solitariness; and if you are never solitary, you are never religious.
Alfred North WhiteheadInventive genius requires pleasurable mental activity as a condition for its vigorous exercise. "Necessity is the mother of invention" is a silly proverb. "Necessity is the mother of futile dodges" is much closer to the truth. The basis of growth of modern invention is science, and science is almost wholly the outgrowth of pleasurable intellectual curiosity.
Alfred North Whitehead
