The landscape problem represents a serious problem in the development of science. Its solution requires... the construction of speculative cosmological scenarios, which posit regions or epochs of our universe for which we presently have no observable evidence. Nonetheless we must insist on taking seriously only scenarios and hypotheses that make falsifiable or strongly verifiable predictions, otherwise people can just make stuff up and the distinction between science and mythology becomes porous. ...there are already candidate solutions that make real, falsifiable predictions.

Women should be permitted to volunteer for non-combat service, [...] We have no real way of knowing whether the kinds of training that teach men both courage and restraint would be adaptable to women or effective in a crisis. But the evidence of history and comparative studies of other species suggest that women as a fighting body might be far less amenable to the rules that prevent war from becoming a massacre and, with the use of modern weapons, that protect the survival of all humanity. That is what I meant by saying that women in combat might be too fierce.
Margaret Mead
When we seek a textbook case for the proper operation of science, the correction of certain error offers far more promise than the establishment of probable truth. Confirmed hunches, of course, are more upbeat than discredited hypotheses. Since the worst traditions of "popular” writing falsely equate instruction with sweetness and light, our promotional literature abounds with insipid tales in the heroic mode, although tough stories of disappointment and loss give deeper insight into a methodology that the celebrated philosopher Karl Popper once labeled as "conjecture and refutation.”.
Stephen Jay Gould
If the world is an aggregate of relatively independent regions, then any assumption of universal laws is false and a demand for universal norms tyrannical: only brute force (or seductive deception) can then bend the different moralities so that they fit the prescriptions of a single ethical system. And indeed, the idea of universal laws of nature and society arose in connection with a life-and-death battle: the battle that gave Zeus the power over the Titans and all other gods and thus turned his laws into the laws of the universe.
Paul Karl Feyerabend
Contemporary philosophers have exercised themselves with the problem of our knowledge of other minds. Enmeshed in the dogma of the ghost in the machine, they have found it impossible to discover any logically satisfactory evidence warranting one person in believing that there exist minds other than his own. I can witness what your body does, but I cannot witness what your mind does, and my pretensions to infer from what your body does to what your mind does all collapse, since the premises for such inferences are either inadequate or unknowable.
Gilbert Ryle
If there is no point in the universe that we discover by the methods of science, there is a point that we can give the universe by the way we live, by loving each other, by discovering things about nature, by creating works of art. And that-in a way, although we are not the stars in a cosmic drama, if the only drama we're starring in is one that we are making up as we go along, it is not entirely ignoble that faced with this unloving, impersonal universe we make a little island of warmth and love and science and art for ourselves. That's not an entirely despicable role for us to play.
