Pessimism is a very easy way out when you’re considering what life really is, because pessimism is a short view of life. If you look at what is happening around us today and what has happened just since you were born, you can’t help but feel that life is a terrible complexity of problems and illnesses of one sort or another. But if you look back a few thousand years, you realize that we have advanced fantastically from the day when the first amoeba crawled out of the slime and made its adventure on land. If you take a long view, I do not see how you can be pessimistic about the future of man or the future of the world.

the thing about pessimism is that in most cases it's nothing more than a front behind which a body can hide its most sweetful yet painful hopes. please forgive mine.

I can't be a pessimist because I am alive. To be a pessimist means that you have agreed that human life is an academic matter. So, I am forced to be an optimist. I am forced to believe that we can survive, whatever we must survive.

The the question whether I am a pessimist or an optimist, I answer that my knowledge is pessimistic, but my willing and hope are optimistic.

Hope locates itself in the premises that we don’t know what will happen and that in the spaciousness of uncertainty is room to act. When you recognize uncertainty, you recognize that you may be able to influence the outcomes–you alone or you in concert with a few dozen or several million others. Hope is an embrace of the unknown and knowable, a alternative to the certainty of both optimists and pessimists. Optimists think it will all be fine without our involvement; pessimists take the opposite position; both excuse themselves from acting. It’s the belief that what we do matters even though how and when it may matter, who and what it may impact, are not things we can know beforehand. We may not, in fact, know them afterward either, but they matter all the same, and history is full of people whose influence was most powerful after they were gone.

A pessimist is somebody who complains about the noise when opportunity knocks.

Pessimism doesn’t change the reality; it prolongs the status quo. And it brings everyone down. It’s only ever lose-lose. Optimism and faith coupled with pragmatism change the reality. Self-belief and self-reliance change the reality. Boldness to explore new ideas changes the reality. A vision powered by effort and energy changes the reality.

We need optimism and confidence to keep going and convince others to join our cause, but negativity and pessimism help us see problems so we can make them better. Yes, the former feel much better, but both are necessary.

Pessimism is, in brief, playing the sure game. You cannot lose at it; you may gain. It is the only view of life in which you can never be disappointed. Having reckoned what to do in the worst possible circumstances, when better arise, as they may, life becomes child's play.

The optimists and the pessimists: I have been studying them for the past twenty-five years. The defining characteristic of pessimists is that they tend to believe bad events will last a long time, will undermine everything they do, and are their own fault. The optimists, who are confronted with the same hard knocks of this world, think about misfortune in the opposite way. They tend to believe defeat is just a temporary setback, that its causes are confined to this one case. The optimists believe defeat is not their fault: Circumstances, bad luck, or other people brought it about. Such people are unfazed by defeat. Confronted by a bad situation, they perceive it as a challenge and try harder.

People assume it’s a matter of personality, the difference between optimists and pessimists. But I believe it all comes down to an inability to forget. The greater your powers of retention, the slimmer your chances at optimism.

Pessimism is not in being tired of evil but in being tired of good. Despair does not lie in being weary of suffering, but in being weary of joy. It is when for some reason or other good things in a society no longer work that the society begins to decline; when its food does not feed, when its cures do not cure, when its blessings refuse to bless.

Pessimism n.
A philosophy forced upon the convictions of the observer by the disheartening prevalence of the optimist with his scarecrow hope and his unsightly smile.
