A. C. Grayling offers the following description of currently active followings of Wittgenstein (page 129):
The Wittgensteinians accordingly make a distinctive although relatively small group in contemporary philosophy, studying Wittgenstein's texts closely and applying his methods, with some of them refusing to take more recent developments in philosophy seriously on the grounds that they involve departures from Wittgenstein's ideas. A considerable amount has been published by these followers, ranging from exegesis to hagiography, and including some original work which has variously been controversial and stimulating.
On page 132 he mentions Janik and Toulmin's Wittgenstein's Vienna which might be an example of what he is referring to (or might not). I wonder which philosophers could be considered to fit the above description and are currently active.
Hence the question: Which currently active philosophers would fit Grayling's description of Wittgenstein followers?
