Researchers from the 1940's through the present have found that normal, sighted people can echolocate - that is, detect properties of silent objects by attending to sound reflected from them. We argue that echolocation is a normal part of our perceptual experience and that there is something 'it is like' to echolocate. Furthermore, we argue that people are often grossly mistaken about their experience of echolocation. If so, echolocation provides a counterexample to the view that we cannot be mistaken about (...) our own current phenomenology. (shrink)

Philosophers tend to assume that we have excellent knowledge of our own current conscious experience or 'phenomenology'. I argue that our knowledge of one aspect of our experience, the experience of visual imagery, is actually rather poor. Precedent for this position is found among the introspective psychologists of the late nineteenth and early twentieth centuries. Two main arguments are advanced toward the conclusion that our knowledge of our own imagery is poor. First, the reader is asked to form a visual (...) image, and it is expected that answering questions about certain basic features of that experience will be difficult. If so, it seems reasonable to suppose that people could be mistaken about those basic features of their own imagery. Second, it is observed that although people give widely variable reports about their own experiences of visual imagery, differences in report do not systematically correlate with differences on tests of skills that psychologists have often supposed to require visual imagery, such as mental rotation, visual creativity, and visual memory.

We argue that echolocation is a normal part of our conscious, perceptual experience. Despite this, we argue that people are often grossly mistaken about their experience of echolocation. If so, echolocation provides a counterexample to the view that we cannot be seriously mistaken about our own current conscious experience.

Little, Brown, 1992 Review by Glenn Branch on Jul 5th 1999 Volume: 3, Number: 27.

To study conscious experience we must, to some extent, trust introspective reports; yet introspective reports often do not merit our trust. A century ago, E.B. Titchener advocated extensive introspective training as a means of resolving this difficulty. He describes many of his training techniques in his four-volume laboratory manual of 1901- 1905. This paper explores Titchener's laboratory manual with an eye to general questions about the prospects of introspective training for contemporary consciousness studies, with a focus on the following examples: (...) introspective knowledge of the combination tones that arise when a musical interval is played; the 'flight of colours' in the afterimage of a field of bright, broad- spectrum light; and the possibility of non-obvious visual illusions. Introspective training appears to have some merit, but also to involve significant hazards. (shrink)

There is a pattern of miscommunication bedeviling the people working on consciousness that is reminiscent of the classic Abbott and Costello ‘ Who ’ s on First?’ routine. With the best of intentions, people are talking past each other, seeing major disagreements when there are only terminological or tactical preferences — or even just matters of emphasis — that divide the sides. Since some substantive differences also lurk in this confusion, it is well worth trying to sort out. Much of (...) the problem seems to have been caused by some misdirection in my apologia for heterophenomenology, advertised as an explicitly third - person approach to human consciousness, so I will try to make amends by first removing those misleading signposts and sending us back to the real issues. On the face of it, the study of human consciousness involves phenomena that seem to occupy something rather like another dimension : the private, subjective, ‘ first - person ’ dimension. Everybody agrees that this is where we start. What, then, is the relation between the standard ‘ third - person ’ objective methodologies for studying meteors or magnets, and the methodologies for studying human consciousness? Can the standard methods be extended in such a way as to do justice to the phenomena of human consciousness? Or do we have to find some quite radical or revolutionary alternative science? I have defended the hypothesis that there is a straightforward, conservative extension of objective science that handsomely covers the ground — all the ground — of human consciousness, doing justice to all the data without ever having to abandon the rules and constraints of the experimental method that have worked so well in the rest of science. This third - person methodology, dubbed heterophenomenology, is, I have claimed, the sound way to take the first person point of view as seriously as it can be taken. (shrink)

One of the striking, even amusing, spectacles to be enjoyed at the many workshops and conferences on consciousness these days is the breathtaking overconfidence with which laypeople hold forth about the nature of consciousness Btheir own in particular, but everybody =s by extrapolation. Everybody =s an expert on consciousness, it seems, and it doesn =t take any knowledge of experimental findings to secure the home truths these people enunciate with such conviction.

In the late 1960s, I created a joke dictionary of philosophers' names that circulated in samizdat form, picking up new entries as it went. The first few editions were on Ditto masters, in those pre-photocopy days. The 7th edition, entitled The Philosophical Lexicon , was the first properly copyrighted version, published for the benefit of the American Philosophical Association in 1978, and the 8th edition (brought out in 1987), is still available from the APA. I continue to receive submissions of (...) further entries, but I doubt that there will ever be a 9th edition. The 8th edition lists two distinct entries for Dick Rorty. (shrink)
