I've been looking for some books that could help me clarify some things I'm confused about, but I've not been very successful in my quest so far, so I try to ask for help and advice here.
It happens to me quite often (if not always), and I think it can be observed in everyday life too, that actions that might be considered "good" a priori can actually have more "negative" than "positive" consequences. As the saying goes: the road to hell is paved with good intentions. And the opposite also seems to be true (sometimes at least): some actions that might be considered as bad a priori can actually have benefits.
So why is it that everyone seems so clear about what is "good" and what is "bad"? How do I know that an action I consider good won't backfire on me or others at some point? What should we do when we realize that we have absolutely no idea what the negative consequences of our actions might be?
I'm looking for books that address these questions. Do you have any references to suggest? My last philosophy classes were in high school and I'm not sure how or where to look for books on such subjects. I have of course tried Google but the results have not been very conclusive.
And if you've ever thought about these questions yourself, your thoughts and answers on the subject are obviously welcome too.
Thank you in advance for your help!
