Reddit reviews The Ethical Life: Fundamental Readings in Ethics and Contemporary Moral Problems

There's lots of them, so I think one should start in the area they're most interested in and then branch from there.

Here' a general survey of the areas of philosophy.

The areas usually have their own articles in the Stanford Encyclopedia of Philosophy with extensive bibliographies (e.g. Modal Logic). Same goes for particular problems from these areas, like Truth, and some of the philosophers themselves (e.g. Bertrand Russell). There's also the Internet Encyclopedia of Philosophy

For less technical and more structured introductions, there are plenty of textbooks, like Logic, This is Philosophy of Mind or The Fundamentals of Ethics. Books from the Very Short Introductions series are sometimes decent (e.g. Metaphysics), and they really are short.

The textbooks usually have further reading recommendations, some of which are compiled readers like The Blackwell Companion to Consciousness or The Ethical Life: Fundamental Readings in Ethics and Contemporary Moral Problems. I think these are good starting points as well.

Most of the books are going to be available on libgen of course.

And then there's of course podcasts. Some of the good ones I like:

• Philosophy Bites – very concise episodes with experts speaking on singular subjects
  
• Elucidations – basically the above, but with longer episodes
  
• Very Bad Wizards – a philosopher an a psychologist meme a lot and then discuss some ethics
  
• The Panpsycast – meant as beginner introductions to various subjects; kinda hit-and-miss for me I guess, but the eps where they invite experts to speak are good
  
• History of Philosophy without any gaps – they mean the title
  
  Lastly, Gregory B. Sadler is a big guy.
