Thomasson is a gifted writer and philosopher, with a distinctive voice and a forceful message. Norms and Necessity is important and timely, making a strong contribution to one of philosophy's central problems. In support of that verdict I would say that it is the clearest and best-researched work on the nature of modality--the philosophical problems surrounding notions of necessity and possibility--to appear since Saul Kripke and David Lewis put modality back into the centre of the philosophical landscape some fifty years ago. It marks a radical departure from the tradition that they inspired, which makes it especially important.
