What role does justice play in post-colonial philosophy? Why was an education in philosophy important for post-colonial thinkers? How did financial considerations and the international market affect the pre-colonial, colonial, and post-colonial world

By post-colonial, do you mean America after independence, or the post-world war two world when the European empires were gone? Either way, there is an interesting philosophy forum where a lot of people have been discussing questions like these, you could pick up some ideas there or join the debate.
