Popper on Ignorance

"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" (Popper 2002 [1963], 38).

"our knowledge can be only finite, while our ignorance must necessarily be infinite"  (Popper 2002 [1963], 38).

"while differing widely in the various little bits we know, in our infinite ignorance we are all equal"  (Popper 2002 [1963], 38).

we must "admit that all knowledge is human; that it is mixed with our errors, our prejudices, our dreams, and our hopes; that all we can do is to grope for truth even though it be beyond our reach"  (Popper 2002 [1963], 39).

"truth is beyond human authority" (Popper 2002 [1963], 39).
