“We must convince each generation that they are transient passengers on this planet earth. It does not belong to them. They are not free to doom generations yet unborn. They are not at liberty to erase humanity's past nor dim its future.”

“Many environmental threats in the twenty-first century will coincide with the dying out of the post-World War II baby boomers. Future historians may call them the fortunate generation. Their fortune was to have been born after the discovery of penicillin, to have lived in an age of selfish overconsumption of resources, and to have died before the oil ran out.”

“The novelties of one generation are only the resuscitated fashions of the generation before last.”

“Wilde's permanent celebrity belongs to literature, and only his transient notoriety to police news.”

“It may be that considerations of justice are a central element of ethical thought that transcends the relativism of distance. Perhaps this, too, comes from a feature of the modern world. We have various conceptions of social justice, with different political consequences; each has comprehensible roots in the past and in our sentiments. Since we know that we do not accept their past legitimations, but otherwise are not sure how to read them, we are disposed to see past conceptions of justice as embodiments of ideas that still have a claim on modern people. To this extent, we see them as in real confrontation with each other and with modern ideas.”

“But whether the risks to which liberty exposes us are moral or physical our right to liberty involves the right to run them. A man who is not free to risk his neck as an aviator or his soul as a heretic is not free at all; and the right to liberty begins, not at the age of 21 years but 21 seconds.”

“Life is no brief candle to me. It is a sort of splendid torch which I have got a hold of for the moment, and I want to make it burn as brightly as possible before handing it on to future generations.”
