What makes a person "good" at philosophy, and what people–who are currently working–are really good?

I've been studying philosophy on my own time over the last couple of years, and have come across many different people with different ideas. I just wanted to know how one considers another "good" at philosophy? Also, can you name some good philosophers? People who are considered good from multiple fields? Cheers and thanks for the info.

Being a good philosopher requires a few different aspects but at a bare minimum a philosopher needs to be able to read, understand, and critically analyze dense philosophical texts and papers.  An undergraduate degree in philosophy really focuses on this aspect of the education.  To go further in philosophy you need to integrate into a problem context.  Essentially what this means is that you have thought about a philosophical problem long enough that you have a novel idea that adds to the relevant discourse.  Being a good writer is generally ancillary to being a good philosopher and it is possible to be a good philosopher and a bad writer.  That said, as a philosopher you should try to be as clear and concise in your writing as possible because if people have to difficult a time understanding what you are trying to say then they will not consider your work worth their time.

There is a whole history of philosophy full of good philosophers but a few of the more recent ones that have gained a lot of attention in the past 50 years or so are people like, Saul Kripke, Philippa Foot, Michael Thompson, Hilary Putnam, Peter Singer, John Rawls, Thomas Nagel, David Lewis, Derek Parfit, and Gregory Vlastos.  This list is by no means exhaustive but names a good amount of philosophers who worked in the second half of the twentieth century and are generally regarded within their fields as having made a major contribution.
