But the Mary case suggests that doing so requires rejecting the complete-knowledge claim, the learning claim, or the non-deducibility claim.

But there are other mental properties that resist the kind of story that seems plausible for beliefs and desires. Denis Robinson raises the possibility that Lewis’s argument can be extended to produce a far-reaching and puzzling result. Qualia and Materialism in Philosophy of Mind.

University of Minnesota Press.

Metaphysical physicalism simply asserts that what there is, and all there is, is physical stuff and its relations. Mary is a brilliant scientist who is, for whatever reason, forced to investigate the world from a black and white room via a black and white television monitor. A variant of the obvious absurdity objection is that epiphenomenalism leads to a feeling of loss of self, or a sense that we can no longer regard our actions as ours.


In Epi;henomenal and Jackson he argues that the argument goes wrong in presupposing a false view about sensory experience and that it can be answered by endorsing strong representationalism: Also, he can reasonably complain that the objection assumes a causal theory of knowledge that is not appropriate for phenomenal knowledge.

In light of such considerations, Churchland distinguishes between quaoia senses of knowing, “knowing how” and “knowing that”, where knowing how refers to abilities and knowing that refers to knowledge of facts. Davidson, Actions and EventsOxford: We have ended up agreeing with Laurence Nemirow and David Lewis [the authors of the ability-hypothesis strategy] on what happens to Mary on her release.

Given this information and her extraordinary capacity, Martha has the ability to imagine cherry red, but as long as she does not exercise this ability she does not know what it is like to see cherry red.


The following discussion will briefly indicate two ways in which this distinction can be made, and the kind of epiphenomenalistic questions that ensue. Accepting the knowledge argument forces philosophers to weigh such costs and benefits and develop new, non physicalist accounts. On this view, a fact might be physical but not discursively learnable. Various criticisms and defenses of these assumptions are discussed.

If phenomenal properties are intrinsic properties of fundamental physical objects, and the latter stand in lawlike relations, then lawlike relations will hold between phenomenal properties and some physical occurrences.

As a third step, all three results appear to conflict with physicalism. The Dualist View About the Knowledge Argument There has not been much discussion of the knowledge argument from a dualist perspective. It has been argued against Nemirow that the ability to imagine having an experience of a particular kind is neither necessary nor sufficient for knowing what it is like to have that kind of experience.

In Conee’s account, one can come to know be acquainted with a phenomenal quality only by experiencing it, but not by knowing facts about it as Mary did. Nonetheless, absent insight into the necessity of the connection between neural properties and qualitative properties, we are arguably in an explanatory position similar to traditional epiphenomenalism.

Benjamin Libet argues that experiments done by himself and others show that certain voluntary actions are preceded by neural events that occur prior to awareness of the intention to act. Animated cartoons are full of causal illusions. Tye wishes to accommodate the natural intuition that Mary before release cannot fully understand the nature of phenomenal blueness she doesn’t really know what it is to have a blue experience.

It rests on the idea that someone who has complete physical knowledge about another conscious being might yet lack knowledge about how it feels to have the experiences of that being.

Knowledge argument

David Bourget – – Philosophy and Phenomenological Research 95 2: Epiphenomenalism is absurd; it is just plain obvious that our pains, our thoughts, and our feelings make a difference to our evidently physical behavior; it is impossible to believe that all our behavior could be just as it is even if there were no pains, thoughts, or feelings.


Introduction The knowledge argument aims to refute physicalism, the doctrine that the world is entirely physical. Both Romanes and James follow their statements of the view with arguments against its acceptance. Jackson,replies to this and several other arguments against epiphenomenalism. Published in The Fortnightly Review16 December: Lycan’s account of Mary’s epistemic progress can be put, roughly, like this: That the taste of Vegemite has this physical effect is a piece of physical information.

Qualia: The Knowledge Argument (Stanford Encyclopedia of Philosophy)

And on the latter, experiential interpretation, the acquaintance hypothesis trivializes the learning claim: More Physicalist Responses Most physicalist responses to the knowledge argument fall into three categories: Author Information Torin Alter Email: Epiphenomenl, Daniel and Yujin Nagasawa.

Probably the most common reaction to this is simply to doubt the claim.

A reward system that can lead to quick decisions and a sensory system that provides discriminations for use in longer term planning would both confer advantages; and these systems would, in general, have to work together in a successful organism.

He [the archangel] would know exactly what the microscopic structure of ammonia must be; but he would be totally unable to predict that a substance with this structure must smell as ammonia does when it gets into the human nose.

The essay is not solely concerned with animals: These are the properties for which functionalism is most plausible, e. Barring neural events that are inexplicably in violation of biological constraints on their conditions of activation, there must be an adequate physical cause of every link in the causal chain leading to behavior. Falling barometers are regularly followed by storms, but do not cause them. In the case of the conceivability argument, the gap is put in terms of conceivability:
