@Deftil,
Here is are a few of mine
While the whole of philosophy is extensive and complicated, can it be reduced to the questions below
1) what is the nature of the universe? Where does it come from? Of what is it made? How did it come to exist? What is its purpose? By what process does it change? Is it evolving or devolving? Does it function by itself or would it degenerate to chaos without some kind of intelligent control?
2) Is there a Supreme Being? If so, what is His nature?
3) What is the place of man in the universe? Is man the highest fruit of the universe or is he just an insignificant speck in infinite space-or something in between?
4) Does the spirit of man descend into matter from higher spiritual realms, or has it evolved from matter?
5) Is the universe conscious or unconscious of man? If it is aware, is it warm and friendly to him, or cold and indifferent, or even hostile?
6)) what is reality?
7) What is mind?
(a) What is thought? Is thought real?
(b) Where do ideas come from?
8) Are there laws that control thought?
9) Which is superior: mind or matter?
10) Has mind created matter or has matter evolved mind?
11) What determines the fate of each individual?
12) Is man a creator and mover of his life, or does he lives at the effect of forces over which he has little control?
13) Does free will exist or are our lives determined by outside factors-and if so, what are those factors?
14) Is there a Supreme Force that intervenes in our lives?
(a) Or is everything pre-determined from the beginning of time;
(b) Or is life just random, full of coincidence and accident?
15 What is good and what is bad or evil?
(a) What is moral?
(b) What is ethical?
16 Who decides good and bad, right and wrong; and by what standard?
17 Is there an absolute standard of good and bad beyond one's the personal opinions?
18 Should good and bad be determined by custom, by rational law, or by the situation? do we have no choice.
19 What is the ideal relation between the individual and the state? Should the individual serve the state or the state serve the individual? What is the best form of government and what is the worst? When is a man justified in rebelling against the established order and creating a new state?
20 What happens at death? Is death the end of everything or is there a soul in man that continues to exist beyond death? If so, is that soul immortal or does it too eventually cease to exist? If the soul does continue to exist after death, what is the nature of that existence? If there is an existence after death, is "good" rewarded and "bad" punished? If so, how do you reconcile this with the concept of predestination?
