The spread of civilisation may be likened to a fire; first, a feeble spark, next a flickering flame, then a mighty blaze, ever increasing in speed and power.
— Nikola Tesla

I am very excited to be supporting one of the world's most visionary efforts to seek basic answers to some of the fundamental question about our universe and what other civilisations may exist elsewhere.
Paul Allen civilisation quote

If no set of moral ideas were truer or better than any other, there would be no sense in preferring civilised morality to savage morality.
— C. S. Lewis

Civilisation will not last, freedom will not survive, peace will not be kept, unless a very large majority of mankind unite together to defend them and show themselves possessed of a constabulary power before which barbaric and atavistic forces will stand in awe.
— Winston Churchill

Nothing can be more abhorrent to democracy than to imprison a person or keep him in prison because he is unpopular. This is really the test of civilisation.
— civilisation quotation by Winston Churchill
