That's a good or a bad question*, I think that you may know that O.o.
Going fishing as-we-may-say, one's philosophy ought not to be too difficult otherwise it would
be too hard-to-learn.^
So unlike the good guidance of others here we may say "that is too difficult, I am not going to try..".
So try we must... hence we can "develop this as we go" meaning meeting new problems and their
(existing or new) solutions.
I & others have talked & written about one such problem - man's environmental problematic influence..
And even tentative solutions have been put forward for sharing & discussion..
* see Plogsties recent answer to the question, Why is it that Philosophers (often) in particular
are blind-to-their-own mistakes ?
^ hard-to-learn for instance if we divide this-here-world of ours into 1) the present world
or 2) an ideal, idealised world (just of mistakes, for example)
