Why did all the ancient philosophers seem so fascinated by astronomy? Their interest in math and "physics" is understandable, as math can be seen as very similar to certain branches of philosophy in that it is not the study of a particular existence, but, rather, the study of "existence," and physics is the study of the seemingly occult laws that govern everything, which is also very similar to philosophy in a sense, but astronomy is just the extrapolation of those two fields on "arbitrarily chosen" pieces of mass. Math, and even physics to a large extent, are "implicit" (for lack of better term) to existence, while astronomy is wholly explicit.
Humans can apparently commit to beliefs that are ultimately contradictory or incompatible. For instance, the one person, unless they're shown a reason to think otherwise, could believe that both quantum mechanics and relativity correspond to reality. What I wanted to ask is -- the ability to hold contradictory beliefs might sometimes be an advantage; for instance, both lines of inquiry could be pursued simultaneously. Is this an advantage that only organic brains have? Is there any good reason a computer couldn't be designed to hold, and act on, contradictory beliefs?
If the basis of morality is evolutionary and species-specific (for instance, tit for tat behaviour proving reproductively successful for humans; cannibilism proving reproductively successful for arachnids), is it thereby delegitimised? After all, different environmental considerations could have favoured the development of different moral principles.
When a person, and especially a talented one, dies young, people sometimes mourn not just what they have in fact lost, but what might have been. But is mourning what might have been predicated on the belief that things could have been otherwise? And if someone is a thoroughgoing determinist and thinks that there's only one way things ever could have turned out, would it be irrational for such a person to mourn what might have been?
