Which intellectual profoundly influenced early 20th-century authors, inspiring them to radically rethink concepts of human identity?

Explanation

Both Sigmund Freud and James George Frazer significantly shaped early twentieth-century literature by encouraging new perspectives on human nature and identity. Immanuel Kant, however, did not have the same direct influence on these writers during that period. Therefore, the correct answer includes Freud and Frazer but excludes Kant.
