We Are Responsible for the Future
The possibilities that lie in the future are infinite. When I say ‘It is our duty to remain optimists,’ this includes not only the openness of the future, but also that which all of us contribute to it by everything we do.
We are responsible for what the future holds in store. It is our duty, not to prophesy evil, but, rather, to fight for a better world..
Karl Popper, The Myth of the Framework: In Defense of Science and Rationality
The Principle of Optimism
All evils are caused by insufficient knowledge.
Optimism is a way of explaining failure, not prophesying success. It says that there is no fundamental barrier, no law of nature or supernatural decree, preventing progress.
Whenever we try to improve things and fail, it is not because the spiteful (or benevolent) gods are thwarting us or punishing us for trying, or because we have reached a limit on the capacity of reason to make improvements, or because it is best that we fail, but always because we did not know enough, in time.
In addition, optimism is a stance towards the future, because nearly all failures, and nearly all successes, are yet to come.
