Abstract for Mackie’s Talk

In this paper I discuss a thesis that I call ‘The Appearance of Mind-Independence’, a thesis to the effect that, to the subject of an ordinary perceptual experience, it seems that the experience involves the awareness of a mind-independent world. Although this thesis appears to be widely accepted, I suggest that it may be challenged. Whether such a challenge can be maintained is especially relevant to the assessment of any theory, such as Berkeley’s idealism, according to which the only objects of which we are truly aware in perception are mind-dependent objects. But the issue is also of significance for the philosophy of perception more generally.
