The ability to play is one of the principal criteria of mental health.

In the 2nd edition (1989), Montagu rephrased this a bit less prosaically: "Play is, of course, among the clearest of neotenous behavioral traits; it is the neoteny of the intellect, a principal criterion of mental health." Montagu uses the term "neoteny" to mean "growing young."

Montagu, Ashley
We begin to understand the goal of life is to die young — as late as possible!
Ashley Montagu (1905-1999) British-American anthropologist and humanist [b. Israel Ehrenberg, a/k/a Montague Francis Ashley-Montagu]
Growing Young, ch. 1 (1981)
Sometimes paraphrased: "The idea is to die young as late as possible."
Bigotry and science can have no communication with each other, for science begins where bigotry and absolute certainty end. The scientist believes in proof without certainty, the bigot in certainty without proof. Let us never forget that tyranny most often springs from a fanatical faith in the absoluteness of one’s beliefs.
