Timeline

1932

Frederick Irwin "Fred" Dretske (December 9, 1932 – July 24, 2013) was an American philosopher noted for his contributions to epistemology and the philosophy of mind.

Born to Frederick and Hattie Dretske, Dretske first planned to be an engineer, attending Purdue University.

He changed his mind after taking the university's only philosophy course, deciding philosophy was the only thing he wanted to do in his life.

1954

After graduating in 1954 with a degree in electrical engineering and serving in the army, he enrolled in graduate school in philosophy at the University of Minnesota, where he received his PhD in 1960.

His dissertation, supervised by May Brodbeck, was on the philosophy of time.

1960

Dretske's first academic appointment was to the University of Wisconsin–Madison in 1960, where he rose to the rank of full Professor.

1988

In 1988 he was recruited to Stanford University, where he was the Bella and Eloise Mabury Knapp Professor of Philosophy.

Dretske's work on belief begins in the last third of Knowledge and the Flow of Information, but the theory changed again in the book that followed, Explaining Behavior (1988).

There Dretske claims that actions are the causing of movements by mental states, rather than the movements themselves.

Action is thus a partly mental process itself, not a mere product of a mental process.

For the meaning – the content – of a belief to explain an action, on this view, is for the content of the belief to explain why it is that the mental state is part of a process that leads to the movement it does.

According to Explaining Behavior, a belief that s is F is a brain state that has been recruited (through operant conditioning) to be part of movement-causing processes because it did, when recruited, carry the information that s is F. Being recruited because of carrying information gives a thing (such as a brain state) the function of carrying that information, on Dretske's view, and having the function of carrying information makes that thing a representation.

Beliefs are thus mental representations that contribute to movement production because of their contents (saying P is why the brain state is recruited to cause movement), and so form components of the process known as acting for a reason.

An important feature of Dretske's account of belief is that, although brain states are recruited to control action because they carry information, there is no guarantee that they will continue to do so.

Yet, once they have been recruited for carrying information, they have the function of carrying information, and continue to have that function even if they no longer carry information.

This is how misrepresentation enters the world.

Dretske's last monograph was on consciousness.

Between the representational theory of belief, desire, and action in Explaining Behavior and the representational theory of consciousness found in Naturalizing the Mind, Dretske aimed to give full support to what he calls the "Representational Thesis".

This is the claim that:

(1) All mental facts are representational facts, and

(2) All representational facts are facts about informational functions.

1994

He was awarded the Jean Nicod Prize in 1994.

1998

He remained at Stanford until his retirement in 1998, after which he was professor emeritus in philosophy at Stanford and senior research scholar in philosophy at Duke University until his death.

2003

He was elected a Fellow of the American Academy of Arts & Sciences in 2003.

Upon his death, he was survived by his second wife Judith Fortson, by his children Kathleen Dretske and Ray Dretske, and by a stepson, Ryan Fortson.

Dretske held externalist views about the mind, and thus he tried in various writings to show that by means of mere introspection one actually learns about their own mind less than might be expected.

His later work centered on conscious experience and self-knowledge,

Dretske's first book, Seeing and Knowing, deals with the question of what is required to know that something is the case on the basis of what is seen.

According to the theory presented in Seeing and Knowing, for a subject S to be able to see that an object b has property P is:

(i) for b to be P (ii) for S to see b (iii) for the conditions under which S sees b to be such that b would not look the way it now looks to S unless it were P and (iv) for S, believing that conditions are as described in (iii), to take b to be P.

For instance, for me to see that the soup is boiling – to know, by seeing, that it is boiling – is for the soup to be boiling, for me to see the soup, for the conditions under which I see the soup to be such that it would not look the way it does were it not boiling, and for me to believe that the soup is boiling on that basis.

Dretske's next book returned to the topic of knowledge gained via perception but substantially changes the theory.

Dretske had become convinced that information theory was required to make sense of knowledge (and also belief).

He signaled this change at the beginning of the new book, opening the Preface with the lines "In the beginning there was information. The word came later."

Information, understood in Dretske's sense, is something that exists as an objective and mind-independent feature of the natural world and can be quantified.

Dretske offers the following theory of information:

A signal r carries the information that s is F = The conditional probability of s's being F, given r (and k), is 1 (but, given k alone, less than 1).

Thus, for a red light (r) to carry the information that a goal (s) has been scored (is F) is for the probability that a goal has been scored, given that the light is red (and given my background knowledge of the world, k), to be 1 (but less than 1 given just my background knowledge).

With this theory of information, Dretske then argued that for a knower, K, to know that s is F = K's belief that s is F is caused (or causally sustained) by the information that s is F.

His theory of knowledge thus replaced conscious appearances with the idea that the visual state of the observer carries information, thereby minimizing appeal to the mysteries of consciousness in explaining knowledge.
