I like Camus, read a lot from him when I also was going through one of my frequent rough times. My favorite would have to be Slavoj Žižek, though. Not anywhere near Camus as far as those fundamental questions of our existence go - but he delivers very sharp and clear observations and explanations of our times. If we could agree to count him as a philosopher, I'd go with Noam Chomsky ;)Slavoj Žižek (born 21 March 1949) is a Slovenian Marxist philosopher and cultural critic. He is currently a senior researcher at the Institute for Sociology and Philosophy, University of Ljubljana in Slovenia, Global Distinguished Professor of German at New York University,[1] and international director of the Birkbeck Institute for the Humanities.[2] He writes widely on a diverse range of topics, including political theory, film theory, cultural studies, theology, and psychoanalysis.
