It is important to distinguish between arbitrary optimism and objective optimism.
Arbitrary optimism is when a person keeps saying that “everything will be all right,” but cannot tell why. It is a form of evasion, which leads one to pursue impossible goals, take unreasonable risks, and forgo the real opportunities in life.
But this is not the kind of optimism that a truly optimistic person has. A promise of a bright future doesn’t really cheer you up if you know it’s unfounded. A true optimist has positive ideas that are true. He is confident he can achieve his goals, because he has chosen goals that he knows are achievable. He has confidence in his ability to create wealth, because he is committed to the means by which man creates wealth: reason. He is confident that, if he should have any failings, he will be able to correct them, because he knows he has a free will that enables him to control his actions. He trusts that he will find rational men with whom he can trade value for value, because he knows that rationality is possible and trade can be mutually beneficial. He isn’t afraid of being independent and acting in his self-interest, because he knows he doesn’t need to sacrifice others for his survival, nor do others need sacrifices from him for theirs. He recognizes that evil exists, but he is confident that he and other good men can overcome evil–because, as Bearster so brilliantly put it, “in the long run, the truth has to win because it has the advantage of being true.”
As far as the subject matter is this-worldly, objective optimism is the only kind of optimism that is sustainable. One may temporarily entertain some false hopes, but as soon as reality pronounces its verdict on them, the unfounded optimism is bound to vanish. What replaces it is up to the person in question: He may either
- recognize his error and adjust his ideas to reflect reality, in due course becoming an objective optimist;
- resign his confidence and become a pessimist ; or
- develop an embittered, perverse “confidence” in things not going well, and become a cynic.
The first of the above three is the choice of moral men: the choice to think and seek virtue. The second is the choice of mediocre people, who are immoral at times but not especially evil: the choice to “park” one’s mind and passively accept one’s fate. The third choice, cynicism, is pessimism run amuck: the choice to actively nurture false ideas, destroy values, and then point at the destruction and say, “See?? I told you!!!”
