Bertrand Russell Quote

Man is essentially a dreamer, wakened sometimes for a moment by some peculiarly obtrusive element in the outer world, but lapsing again quickly into the happy somnolence of imagination. Freud has shown how largely our dreams at night are the pictured fulfilment of our wishes; he has, with an equal measure of truth, said the same of day-dreams; and he might have included the day-dreams which we call beliefs.
