Rationalism is an attitude of readiness to listen to contrary arguments and to learn from experience... of admitting that "I may be wrong and you may be right and, by an effort, we may get nearer the truth."
Karl PopperThe best thing that can happen to a human being us to find a problem, to fall in love with that problem, and to live trying to solve that problem, unless another problem even more lovable appears.
Karl PopperI see now more clearly than ever before that even our greatest troubles spring from something that is [as] admirable and sound as it is dangerous โ from our impatience to better the lot of our fellows.
Karl PopperIn point of fact, no conclusive disproof of a theory can ever be produced; for it is always possible to say that the experimental results are not reliable or that the discrepancies which are asserted to exist between the experimental results and the theory are only apparent and that they will disappear with the advance of our understanding. If you insist on strict proof (or strict disproof) in the empirical sciences, you will never benefit from experience, and never learn from it how wrong you are.
Karl PopperI don't know whether God exists or not. ... Some forms of atheism are arrogant and ignorant and should be rejected, but agnosticismโto admit that we don't know and to searchโis all right. ... When I look at what I call the gift of life, I feel a gratitude which is in tune with some religious ideas of God. However, the moment I even speak of it, I am embarrassed that I may do something wrong to God in talking about God.
