[The aim of science is] to explain what so far has taken to be an explicans, such as a law of nature. The task of empirical science constantly renews itself. We may go on forever, proceeding to explanations of a higher and higher universality.
Karl Popper

True ignorance is not the absence of knowledge, but the refusal to acquire it.
Karl Popper

The more we learn about the world, and the deeper our learning, the more conscious, specific, and articulate will be our knowledge of what we do not know, our knowledge of our ignorance
Karl Popper

Man, some modern philosophers tell us, is alienated from his world: he is a stranger and afraid in a world he never made. Perhaps he is yet so are animals, and even plants. They too were born, long ago, into a physico-chemical world, a world they never made.
