Clearly a bit late to the party, but if you haven't looked into any of the philosophers any of these lectures pertain to, they're worth watching.
However if you've read the source material and have your own opinions already, they probably won't tell you too much you don't already know.
Still, excellent introductions.https://www.youtube.com/playlist?list=P ... 0F1B82E6E8https://www.youtube.com/playlist?list=P ... 4CDCC1DD2Ahttps://www.youtube.com/playlist?list=P ... 0D19B57FC0
Also Classical philosophy is definitely worth looking into and making your own judgments on.
Studying ethics at school was really validating for me. I mean the marks were a nice ego stroke, but the basic concept of teleology is the most compelling ethical component I have come across, it actually makes me feel like I have a place in the world.
Stoicism is effective for that feeling of cosmopolitan role in the world too, but it seemed a bit more idealistic than Aristotelean eudaimonia.
