Highlight the main points that Edward Said makes in the "Introduction to Culture and Imperialism". 

Edward Said's "Introduction to Culture and Imperialism" is a seminal work that explores the complex relationship between Western nations and their former colonies. Here are the main points he makes:

1. Connection between Culture and Imperialism: Said argues that culture and imperialism are inextricably linked. He posits that Western nations used culture as a tool to justify and perpetuate their imperialistic endeavors.

2. Literature and Empire: Said examines how Western literature was used to reinforce imperialistic ideologies. He suggests that many classic Western works contain underlying themes of superiority and domination, which helped to normalize the concept of imperialism.

3. Post-Colonial Identity: Said also explores the concept of post-colonial identity. He suggests that the cultural identity of former colonies is often shaped by their colonial past, leading to a complex and sometimes conflicted sense of self.

4. Resistance and Opposition: Said discusses the ways in which colonized peoples resisted and opposed imperial rule. He highlights the role of native intellectuals and artists in challenging imperialistic ideologies and forging new cultural identities.

5. The Ongoing Impact of Imperialism: Finally, Said argues that the effects of imperialism are still felt today. He suggests that many of the world's current conflicts and inequalities can be traced back to the legacy of Western imperialism.
