Patriotism is a pernicious, psychopathic form of idiocy.

Religion is a good invention in times of stress.

I showed my appreciation of my native land in the usual Irish way: by getting out of it as soon as I possibly could.

You can be a thorough-going Neo-Darwinian without imagination, metaphysics, poetry, conscience, or decency. For 'Natural Selection' has no moral significance: it deals with that part of evolution which has no purpose, no intelligence, and might more appropriately be called accidental selection, or better still, Unnatural Selection, since nothing is more unnatural than an accident. If it could be proved that the whole universe had been produced by such Selection, only fools and rascals could bear to live.

I am of the opinion that my life belongs to the whole community and as long as I live, it is my privilege to do for it whatever I can.
