Philosophy has four forms: wonder, faith, doubt and scepticism. These are not separate categories, but separate ideal possibilities. Modern academic philosophy has fallen, for several centuries, into an error: which is the error of supposing that philosophy is only what I call doubt. Philosophy may be doubt: indeed, it is part of my argument that this is undeniably one element of, or one possibility in, philosophy; but doubt is only one of four points of the compass. In this essay I indicate the nature of each point of the compass as it has been found in the history of philosophy.
This essay, written in Downing College, Cambridge in April 2011, is indebted to the writings cited below, but perhaps especially to the writings of D.C. Stove and S.R.L. Clark. They have suggested to me that breadth is still possible in modern philosophy – something I had begun to doubt.

96 See Priest, who calls these respectively ‘scepticism’ (‘nothing is true’), ‘trivialism’ (‘everything is true’), and ‘dialethism’: which last is his word for his own doctrine that our usual philosophy of doubt breaks down at the limits of thought. Priest is doubtful whether anyone has subscribed to ‘trivialism’. He suggests perhaps Anaxagoras did, and adds that Aristotle thought Heraclitus and Protagoras did.
