This paper is a talk that the late Richard Wollheim gave at Loughborough University in September 1998. It is published here with the permission of Loughborough University and Wollheim's literary executors. The paper begins by reflecting on modes of artistic evaluation, distinguishing evaluations of interest from evaluations of quality. The former, the subject of the paper, are relativized to works of art within particular art forms, and concern ‘the extent to which the methods and the resources of the particular art (...) to which the work belongs have been fruitfully exploited’. The essentialist view of art implicit in this account is recognized and defended, the view that there are necessary truths about each art form explained in terms of the medium used. An examination of drawing is offered, its techniques and achievements explored, with the principal focus on the ways that the media of drawing are utilized in the service of representing an object. The methods of delineation and form-drawing are highlighted: ‘form-drawing, like delineation, has to be understood through the co-operation between artist and spectator, and, in both cases, it is ultimately the hand of the artist that has to respond to the eye of the spectator’.
