Somewhat late in life, I have come to the conclusion that I should have studied philosophy in college - not as a career mover, but as a means of improving my mind and developing greater insight into fundamental questions that all of us deal with, to some extent. Recently, I have begun to do some reading on my own, and I am wondering whether there are particular readings or other resources that you might suggest to a serious beginner with a strictly amateur, part-time interest.
Thanks to Peter Smith's recommendation, in response to a previous question I posted here, I am currently reading and enjoying "Philosophers Without Gods". Previously, I have read and appreciated Peter Singer's Practical Ethics". These reflect particular interests, but I'd like to start a broader study. Any suggestions?
