Which field? As a Marxist, my favorite work is Politzer's Elementary Principles of Philosophy. It goes over Idealism, Materialism, Dialectical Idealism, and then ties it together into Dialectical Materialism, and then Historical Materialism.

Philosophy has a long history, and it builds and rejects and references previous philosophers all the time, so if you want to study all of philosophy, there is no real waste in starting from the "classical" philosophers like Plato, Aristotle, and Socrates, and moving up from there to your Hegel, Decartes, Nietzche, etc, though I personally stick with Marxists.

This ressource carried me through my BA It's like wikipedia for philosophy but made by actual professors, they know all about the nuances and implications of the texts.

Its almost impossible to "get" most of these authors if you don't have a massive dose of context (which mostly means reading a ton of other texts to understand the ideological context of the philosopher you're reading) and this page helps a lot with it.

If you want to be linear, start with the presocratics (the poem of Parmenides is a great start as it poses the ontological problem or being/non being that is still around today), then Socrates-Plato-Aristotle, then you got the boring medieval part with Aquinas and Augustine. Then it's Descartes, Kant, Hume, Locke for the modern philosophy period (Idealism/Empiricism) it pretty much ends with Hegel.

From Kant on there's what we call the Analytic/Continental split and you'll notice that we are heavily slanted towards the analytic tradition here in the anglo-saxon part of the west. Frege, Wittgenstein and Russel would be analytic philosophers whereas Nietzsche, Foucault and Sartre would be on the other side.

Hope that helps if you got questions lmk.

plato.stanford.edu is a useful reference. Entries are written by Western academics so they have a particular bias and flavor to them, but philosophy students more or less have to bookmark this site.

Don't take it as gospel, and know that he's grinding all sorts of axes, but Bertrand Russell's History of Western Philosophy. Every single-volume history of philosophy is going to have its problems, but this one is extremely readable and frequently funny. It will give you enough familiarity with the course of the tradition to know where to go next.

Some intellectual historians who can give good background to particular time periods you might be interested in - Paul Hazard, Karl Löwith, Will Durant. Edmund Wilson's To The Finland Station covers socialist thought from Jules Michelet to the Russian Revolution.

Hang out in the JC section of any library that uses the Library of Congress classification system; that's where they keep political theory.

I'm observing this thread as well. I'm an uncultured brute when it comes to this topic.

If you just wanna listen this pod has been running 14 years https://historyofphilosophy.net/

Massimo Pigliucci had/has a pretty good philosophy podcast. I don’t know his politics however

Another long running podcast: https://partiallyexaminedlife.com/

I was pretty different back when listening to this so take it with a grain of salt but it was a great way to get introduced to many works in a roughly chronological order (at first).

Look, i'm trying to answer very real flaws i have with solutions i'm likely to be able to execute - are there any summaries of philosophers that would provide context, but permit one to, say, read a book like "of grammatology" without knowing what the fuck Derrida is responding to in every single case? Trusting summary is to trust another person's understanding and intentions in authentic conveyance - but this product may exist, and if it does it may be something I need for the philosophy i'm currently trying to read [derrida lol]

but the point is i'm looking for inroads to philosophy that arent reading everything between plato and whatever the contemporary hot shit philosophers are

I've enjoyed Why Theory (podcast). The hosts are pretty interested in film though, so a lot of it drifts into how philosophical concepts are portrayed in that medium. They are both Lacanian/Freud focused but also cover the gambit of Hegel, Fanon, and much more

Just guess the answer and you'll do better than most, I'm such a hater
