History of western philosophy by Bertrand Russell. Pretty good high level overview of the field. It’s flawed but this really only matters if it’s the only book you read on the subject. Unless you already have a philosopher in mind then I guess I’d start there and read whoever they cite.
The first book I read in a philosophy class was The Little Prince by Antoine de Saint Exupéry, and it’s my favorite book. You might like The Myth of Sisyphus by Albert Camus (free pdf online). You could also watch the Crash Course philosophy videos on YouTube, and then look up the people who pique your interest.
“Not very relevant anymore” is a wild claim considering virtually the entire Western philosophical tradition grows out of Greek philosophy. Locke, Spinoza, Kant, and Nietzsche all inherit, develop, or argue against ideas that originated with the Greeks. Such an anti-intellectual take 😭
That is incredibly flawed logic. Modern philosophers don’t replace the Greeks, they interpret, criticize, and build on them. You can’t truly understand someone like Nietzsche without first understanding Plato and Socrates, it’s like attempting to do calculus without first learning algebra.
