“I'm a pessimist about probabilities, I'm an optimist about possibilities.”
As quoted in "Lewis Mumford Remembers" by Carey Winfrey in The New York Times (6 July 1977)
“To the optimist, pessimists are neurotic; to the pessimist, optimists are deluded.”
Humor in Psychotherapy (2007)
“The Optimist thinks this is the best of all possible worlds, the Pessimist fears it is true.”
This is derived from a statement of James Branch Cabell, in The Silver Stallion (1926) : The optimist proclaims that we live in the best of all possible worlds; and the pessimist fears this is true.

""Our civilization is a perilous adventure for an uncertain prize... Human society is not a constructed thing but a human organization... We are adopting a false method of reform when we begin by operations that weaken society, either morally or materially, by lower its vitality, by plunging it into gloom and despair about itself, by inducing the atmosphere of the sick-room, and then when its courage and resources are at a low ebb, expecting it to perform some mighty feat of self-reformation... Social despair or bitterness does not get us anywhere... Low spirits are an intellectual luxury. An optimist is one who sees an opportunity in every difficulty. A pessimist is one who sees a difficulty in every opportunity... The conquest of great difficulties is the glory of human nature." L. P. Jacks, quoted in American character, by Brander Matthews, 1906

Variant: A pessimist sees the difficulty in every opportunity; an optimist sees the opportunity in every difficulty.
Variant: Both optimists and pessimists contribute to society. The optimist invents the aeroplane, the pessimist the parachute.
This is actually James Branch Cabell from The Silver Stallion (1926)
