I asked my sister to suggest me some authors and I jokingly turned them all down. Kant (too difficult), Kierkegaard (too religious), Heidegger (too Nazist) and Descartes (too old). Actually I'd like something a bit more modern and preferably not something terribly stuffy. The Second Sex is on my to-read list. I love de Beauvoir's fiction. I'm not sure why, but L'Invitée and The Mandarins are some of my favourite books. And those memoirs by de Beauvoir I picked up at the library didn't look particularly read. The Way of Men by Jack Donovan might be an interesting read, too.

I might give Sartre a try. Did he write anything good?

Themes that might interest me: power and authority, sexuality, feminism, linguistics.
Themes that I'm not looking for right now: religion.
