For the last year of my Open University BSc degree I studied philosophy. The titles of the units were:-
Human Nature after Darwin
Humans and other animals
Arguments for freedom
Environments, Ethics and Human Concern
Minds and Bodies
Destiny, Purpose and Faith
I studied human rights, womens rights, animal rights, crime and punishment etc.
I found it very down to earth and not at all esoteric.
For my first year I studied mid-Victorian Britain which included the philosophy of John Stuart Mill, called Utilitarianism. Nothing airy fairy about Mr Mill or utilitarianism. He used his influence in governement to help get the vote for working men and he wanted women to have the vote as well because his wife was a very intelligent feminist, but it wasn't to be in his lifetime.
When I first read Plato I was astonished especially as JWs dismissed him as that guy that talks about the immortality of the soul. There is sooooo much more to Plato than that.
Also worth a read are the essays of Michel de Montaigne. Very down to earth.
