I've got a bit of a mishmash philosophy but it all boils down to "Do what you want if it doesn't hurt anybody nonconsensually", "Actions that lead to a net-gain in preference fulfillment are 'good', with a weighting towards those less well off*," "Ends do justify the means, but the means are part of the end**," "The universe is knowable," "Empirical evidence doped with rational logic are the way to know the universe," and "Nothing is 'moral', there are only 'good' actions and 'bad' actions.***"
Everything I do and believe in stems from those points. Some of them are points that are extensions of other points, but I figured I'd lay them out as separate pieces to be clearer.
*Meaning that if you give a beggar a hundred dollars, that is more 'good' than giving a CEO a hundred dollars, even though they are the same action and both would prefer having more money.
**Meaning if you kill a thousand people to get a utopia, the 'end' is a utopia that has been garnered from mass murder. You can't wash your hands of destroying people, even if you didn't actually do it with your own hands.
***Morality leads to doing things that are "moral" rather than things that are "good", as a signalling method. The priests who are against contraception and condom use are so very "moral" and "pious" that they can back a horrible idea that leads to unwanted pregnancies and death-by-STDs on a continent-wide scale, because contraceptives are "immoral" and thus blocking their use is on a higher level than mere "good" actions.
ALSO ALL OF THIS IS IN FLUX, AS ANY GOOD PHILOSOPHY SHOULD BE. NOTHING IS TRUE, EVERYTHING IS PERMITTED.
