If you're into something based on virtue ethics, but slightly more off the beaten path, then I can recommend something by Krishnamurti. Think on These Things is a good one. It's a collection of transcripts of public talks he gave, along with the questions that were asked afterwards (and his responses).

Zen and the Art of Motorcycle Maintenance. I believe it's still the best-selling philosophy book of all time, and for good reason. I'm on my 6th or 7th read-through.

It is often very productive to read a commentary of the work at the same time as the book itself (especially for older ones), which are often called "Companion to X" or "Guide to X". A good companion will clarify historical context, and link to other philosophical current the work is based on, or answering to. These will also contain more subjective commentary that might color your reading - but I would say it's better to be influenced by the companion's author framing than miss the point entirely.

Justice: What's the Right Thing to Do?

by Michael J. Sandel

Basically a crash course in philosophy that will give you an excellent foundation of knowledge.

It’s based on a series of 24 Harvard lectures and each chapter looks at controversial real world problems through the lens of different philosophies to try and work out what’s the right thing to do.

I strongly recommend Parfit's Reasons and Persons (1984). Parfit's writing style is quite accessible, and in my opinion, there's no other book in philosophy that does such a good job (or even comes close, honestly) of covering such a diverse range of important philosophical topics. Some important issues that are discussed in the book:

• Ethical egoism and why it is self-defeating. Gauthier's Morals by Agreement (1986) would be another great read if you are interested in this specific topic.

• An introduction to theories of self-interest, which I believe serves as a fantastic introduction to welfarist ethics.

• Personal identity and the teletransportation paradox. The latter is often discussed as merely a fun thought experiment, but my intuition is actually that it is incredibly important, and I believe that everyone should grapple with the problem. Furthermore, Parfit's answer to the paradox is probably one of the best you will find.

• The ethics of future persons and the mere addition paradox (also known as the repugnant conclusion). The latter is, in my opinion, an incredibly important open question in ethics.

If you enjoyed Hume, you might like Bertrand Russell's History of Western Philosophy. At least you're inspired me to re-read it!

If you're looking for a simple intro into Stoicism, then I can recommend Lessons in Stoicism by John Sellars. The book itself is beautiful, apart from anything else. It's short, extremely accessible, and well written.

Technology and the Virtues by Shannon Vallor. Aimed at technologists, the book asks questions about how we can make tech in a 'virtuous' manner. It draws mostly from three traditions of classical philosophy; Aristotelian, Confucian and Buddhist. It's accessible, relevant, engaging and easy to dip in and out of. Would recommend!
