Descartes� theory of error

 

the scope of apprehension exceeds that of copmrehension

thus all error is avoidable

 

defining responsibility

is this a good analysis of belief

the question of free will with respect to what we do believe

 

Does this get God off the hook?

= analagous to the problem of evil

Descartes� solution is similar to the comon ocommon solution to it

appeal to FW (i.e. our abuse of it)

god is not responsible for it, but we are

\ all error/sin is avoidable

is there any difference between giving someone a tool which is unreliable and giving someone a tool who you know cannot be relied on to use it safely?

e.g. scientists and atomic bomb � by knowingly putting such weapons in the hands of people who may misuse it, the scientists must take some responsibility for the results of their research

surely must bear some resopnsibility for what people do with what you have given them

 

Is belief a dual component state?

is Descartes� theory of belief a good one?

made up of simply 2 parts: understanding + will

Spinoza � very critical � one unified factor at work, not 2 as a pair

will + intellect are one and the same thing

to believe something is simply to understand it to be T

would it be possible to understand something in the same way all day but to choose to believe/disbelieve it

belief disbelief requires D in the way you understand it, comign to understand it in a different way

Is belief voluntary?

we do all feel responsible for what we believe, as though our beliefs are up to us and something we can do something about

we can try not to be so gullible/sceptical � we try to improve our knowledge

such steps would be pointless if our beliefs were out of our control

especially with ethical values/standpoints � that�s a terrible thing to think/believe

makes no sense to hold people resonisble for beliefs unless we believe that they can change them i.e. that they have FW over them

different people faced with the same evidence will come to different conclusions/beliefs

what would explain this difference except individual choices/values/assessments

 

do we really choose our beliefs? are they really within our control?

surely there are some things you just can�the believe

that you�re dead, that today�s Friday, that water�s not wet � impossible for the same person to choose to believe them

beliefs never present themselves to us individually � always connected (cf web-based epistemic structure)

cos already believe that yesterday was Tuesday and believe in the order of the days of the week

never choosing to believe in isolation � always with respect to entire background of beliefs

host of other factors � society, xp, entire context of your life

difficult to see what room is left for FW in choosing our beliefs

leap of faith � will & choice have been relegated to the smallest rump end of belief

can wonder whether will or freedom play any role whatsoever in our belief

FW inversely proportional to conviction

if freedom of belief is so rare, why would Descartes say it�s unlimited

for Descartes, freedom of belief, though omnipresent, is present in degree, more in some cases than others

Descartes�s belief about its presence is the exact opp of the above intuitive view

rather than restriction of freedom, �/span> greatest expr possible about our freedom

in fact, when making up your mind between two close opposites = the lowest grade of freedom

freedom of belief = proportional to convinction, inversely proportional to indifference

Descartes� sense of freedom

not neutrality

if the 2 are indistinguishable, what grounds do you have to choose between them?

freedom = to choose from yourself, your own nature, rather than at the mercy of external

self-determination, the absence of external factors

insofar as what you do flows from your own nature, not influenced by outside

 

Descartes�s doctrine of innate ideas

1st proof of existence of God relies on innate ideas

* Descartes claims that we possess innate ideas, ideas present in us from birth. In putting this forward, he was reviving a doctrine which, in the end, goes back to Plato.

notion of possessing innate ideas is not unique to Descartes � platonic theory of recollection

There are three questions we might ask:

Just what is it that is innate?

* (1) Just what is it that he thought was innate? The simple answer to this question is �ideas�. But unfortunately Descartes uses the term �ideas� to cover several very different things. His use of the term slides between: concepts, beliefs, and sensations.

concepts, propositions/beliefs, sensations

being in possession of the concept of dragon tells you nothing about whether there are dragons

if beliefs are innate, then knowledge is innate - could have innate belief in dragons, and you could be right

when he talks of �innate�, does he mean concept or proposition/belief?

many concepts are complex, containing many different components

if know their components, then know certain truths, e.g. konwing concept of triangle � knowing the propositions about the properties of 3 sides and angles etc.

possession of a concept might entail holding a belief � e.g. concept of God believing he exists

sensations being innate

external sensations producing very different sensations within ourselves

there is nothing like colour in the external world, so in a sense, the sensation of colour is innate

so just what is it that he thinks is innate?

difficult to say

 

In what sense is it innate?

* (2) In what sense is it innate? It is necessary to make a distinction between between occurent properties and dispositional properties. Descartes offers a dispositional account of innate ideas, rather than an occurent one.

innate = an idea that we have at birth � we don�t all know about God, Cartesian metaphysics, geometry etc.

distinction between occurent + dispositional

both belong to things continuously

occurent � attach by virtue of things which they manifest all the time

dispositional - only manifest at certain time, or only have a tendency to manifest

e.g.

wine glass = transparent + fragile

dog = brown + excitable

aspirin = white and soluble

an object can have a dispositional prop even if it never exhibits it � wood is combustible evne if it never burns just because it has a tendency to burn

easy to extend to states of mind

if I know the composer of a piece of music, then it�s because his name is accessible, not that it�s at the forefront of my mind

innate ideas are dispositional

to have a disposition is one thing, but to realise it is very different � it may even be very difficult to realise

e.g. difficult to understand something, like realising the existence of God � doesn�t mean that it isn�t there

* A disposition may be hard to realise. Indeed it may never be realised.

this allows Descartes to give xp a role � xp is the necessary stimulus to bring forward these ideas � the key that unlocks the ideas

* On this theory Descartes can allow that experiential stimulus need not be wholly irrelevant.

but then: impossible to distinguish between something you know and are not using and something you don�t know and can�t know

i.e. latent disposition vs lacking the disposition

but there are lots of things in our mind that we remember but that we worry we�ve lost (???)

Why did he believe in innate ideas?

* (3) Why did he think it was true? Descartes claims that the things which he says are innate, while they are they are know, just could not have been acquired by experience. He uses the example of geometry.

needs to isolate a class of things which, though we know, were not abstracted from or given in xp

5th reply (Gassendi) � perfect geometrical concepts we use: none are actually given in ordinary xp

can�t derive from experience � only because we innately possess them that we can recognise

e.g. seeing a statue in a block of wood, or seeing a face in a lot of lines

to what extent is Descartes rendered redundant by modern science�s explanations of the mental perceptual processes with which we can explain how we see a face in a set of lines

* Innate ideas became a defining issue in the history of philosophy between rationalism and empiricism. But innatism can be an empirically respectable hypothesis.

empiricists � need not hold the doctrine that there are innate ideas

but cannot hold there to be innate knowledge

e.g. noam chomsky � innate ideas to explain children�s ability to learn language � empirical philosophy to be tested against empirical data

so why were empiricists so hostile to the notion of innate ideas

in 17th C: only one explanation to where innate ideas come from � must have come from God, so they must have been true, \ = innate knowledge
