Quote

Humanity will... be confronted with dangers of unprecedented character unless, in due time, measures can be taken to forestall a disastrous competition in such formidable armaments and to establish an international control of the manufacture and use of the powerful materials.

Set religion free, and a new humanity will begin.

Alienation as our present destiny is achieved only by outrageous violence perpetrated by human beings on human beings.

These things will destroy the human race: politics without principle, progress without compassion, wealth without work, learning without silence, religion without fearlessness and worship without awareness.

It's impossible to impose peace, only to create it.

For no art and no religion is possible until we make allowances, until we manage to keep quiet the enfant terrible of logic that plays havoc with the other faculties.

Science, already oppressive with its shocking revelations, will perhaps be the ultimate exterminator of our human species - if separate species we be - for its reserve of unguessed horrors could never be borne by mortal brains if loosed upon the world.

It is individuals who must be encouraged to undertake the unprecedented - and unprecedentedly profitable - effort to prevent the annihilation of the human race.

Promoting tolerance and human dignity is one of mankind's unfinished challenges.
