Spinoza

so

the mind is not the brain

the mind in Spinoza's terms is a much bigger fish

at the same time it is not true to say that we
cannot speak of the brain in mental terms

the brain finally is substance - modified

as such it has both physical and mental characteristics

perhaps it is easier to speak of the idea of the brain

and the physics of it expressed in idea - as idea

so the brain as in the human brain

is clearly an idea of - presumably based on -
in Spinoza's terms - on adequate knowledge

that comes down to sound physics

sound biology

so what we get in these sciences is an objective
picture of the brain

my idea of the brain may be no more than an image -
the grey lump of flesh - which I believe to be
efficacious - largely because this is what I am told

how the brain works

as in the science of the brain is in Spinozistic
terms - to go to the second level of knowledge

the level of common notions and adequate ideas

the idea of the brain at this level

is quite a different matter to the idea we may have
begun with

in simple terms

the brain works as it does

and I may have a conception of it that reflects in
mental terms just what it does

such a conception would be in Spinoza's terms -
adequate

it's a good question though what this adequate
knowledge amounts to

would Spinoza think a complete picture of any
physical system is possible

(brain included)

I think he would

I doubt any scientist or philosopher would hold
to such a conception today

surely all our knowledge is by its nature inadequate

it's just a question of how inadequate

that is - it is a matter of degree

and here of course we are talking of empirical
knowledge

conceptual or logical knowledge is another matter

it seems to me that the so called certainty of
such is not a feature of the world but rather a
formal construction - a design of the concept

and I think one of the best examples of this is
Spinoza's substance

'that which is in itself and conceived through
itself; in other words, that, the conception of
which does not need the conception of another
thing from which it must be formed'

one way of looking at this is to say substance
as defined is defined as that which has no empirical
content - and is defined as that which is conceptually
complete

so in a way it is a definition of certainty

or an explication - of certainty

and of course certainty must be presupposed here
for it to be an explication

so what is the point?

is anything being said?

yes I didn't mean to get on to this track

what I wanted to follow on with was this

OK - I have a conception of - whatever -
let's say the brain

you have a conception

the Royal Academy has a conception

every man an his dog has a conception

I guess we're going to say - at the least -
that the Royal Academy's conception is the
most comprehensive - idea

and yes it may well be

but how do we know?

that is how do we know any of these conceptions
bear on the physical reality of the brain?

how do we know there is a connection?

that one is a reflection of the other?

this is not just a question for Spinoza-ites -
it applies to any such claim to knowledge

one answer to this question might be -

well if knowledge is not this - what is it?

granted no one can look from the outside -
and see if the relation - Spinoza suggests
holds

there is no outside

and I guess - if so -

we must make the best of the inside

Spinoza's theory of mind and matter -
is elegant and simple

and without the problems of others

in terms of elegance and simplicity it wins the day?

also - when we speak of mind

would Spinoza be prepared to say that in a world
without consciousness - human / animal

there is mind?
