When we have achieved world-wide
fragmentation, it is not
unnatural to think about a world-wide integration.
Such
a
universality of conscious being
for mankind was dreamt of by
Dante, who believed that men
would remain mere broken
fragments until they should be united in an inclusive
conscious-
ness. What we have today, instead of a
social consciousness
electrically ordered, however, is a private subconsciousness
or
individual "point of view" rigorously
imposed by older mechani-
cal technology. This is a perfectly natural
result of "culture lag"
or conflict, in a world suspended
between two technologies.

dialectic {Gk. dialektikh [dialektikê]} —
Process of thinking by dialogue,
discussion, debate, or argu-
ment. In ancient Greece, the term was
used literally. Dialectic
is questioning and conversation
for Socrates,
study of the
Forms
for Plato, and careful reasoning for Aristotle.
German philosophers applied the
term more narrowly to
particular patterns of thinking.
Thus, Kant's
"Transcendental
Dialectic" is an attempt to
show the
general futility of abstract
metaphysical speculation,
but dialectic is, for Hegel,
the funda-
mental process of development—in
both thought and reality—
from thesis to antithesis to synthesis.

'uniting' (and thus, also being able to exist after
their 'separation'; which
is only another formulation of
the thesis of the immortality
of the soul,
one of the cornerstones
of Christian theology
and ethics). In fact, there
simply is no such situation;
and therefore there is
also no problem of
'uniting' or 'co-ordination'. {Cash

[11] There
are not two different and originally
contrary objects of
investigation body and thought, but only one
single object, which is the
Bk.XX:18819.
thinking body of living,
real man (or other analogous
being, if such
exists anywhere in the Universe),
only considered from two different
and even opposing aspects or points of view. Living,
real thinking man,
the sole thinking body with which
we are acquainted, does not consist
of two Cartesian
halves 'thought lacking a body' and a 'body
lacking
thought'. In relation to real man
both the one and the other are equally
fallacious abstractions, and one cannot in the
end model a real thinking
man from two equally fallacious abstractions.
[12] That is what
constitutes the real 'keystone' of the whole
system, 1D6
- ONE
a very simple truth
that is easy, on the whole, to understand.
[13] It is not a special
'soul', installed
by God in the human body as in a
temporary residence, that thinks, but the body
of man itself. Thought
is a property, a mode
of existence, of the body, the
same as its
extension,
i.e. as its spatial configuration and position
among other
bodies.
[14] This
simple and profoundly true idea was expressed this way by
Spinoza in the language of his time: thought
and extension are not
two
special substances
as Descartes
taught, but only two attributes of
one Bk.XX:18819.
{

and the same
organ; not two special objects, capable
of existing
separately and
quite independently of each other,
but only two different
and even opposite aspects under
which one and the same
thing
appears, two different modes
of existence, two forms of the manifesta-
{

tion of some third
thing.
{ ^ ? }
{ ? } {
substance that is G-D that
is Nature }
[15] What is
this third thing? Real infinite Nature,
Spinoza answered.
It is Nature that extends in space and 'thinks'. The
whole difficulty of the
Cartesian metaphysics arose
because the specific difference of the real
world from the world as only imagined
or thought of was considered to
be extension, a spatial, geometric
determinateness. But extension as
such just existed in imagination,
only in thought.
For as such it can
generally only be thought
of in the form of emptiness,
i.e. purely
negatively, as the complete absence
of any definite geometric shape.
Ascribing only
spatial, geometric properties to Nature
is, as Spinoza
said, to think of it in an imperfect
way, i.e. to deny it in advance one of
its perfections. And then it
is asked
how the perfection removed from
Nature can be restored to her again.
[16] The same argumentation
applies to thought. Thought as such is
the same kind of fallacious abstraction as emptiness.
In fact it is only a
property, a predicate, an attribute
of that very body which has spatial
attributes. In other words one can say very little
about thought as such;
it is not a reality existing separately from, and
independently of, bodies
{extension}
but only a mode
of existence of Nature's bodies.
Thought and space
do not really exist by themselves, but only
as Nature's bodies linked by
chains of interaction into a measureless and
limitless whole embracing
both the one and the other.
WikipediA
[17] By a simple
turn of thought Spinoza cut the Gordian
knot
of the
'psychophysical
problem', the mystic insolubility of
which still torments
the mass of theoreticians
and schools of philosophy, psychology,
physiology of the higher nervous
system, and other related sciences
that are forced one way or
another to deal with the delicate theme of
the relation of 'thought'
to 'body', of 'spiritual' to 'material', of 'ideal' to
'real', and such like topics.
[18] Spinoza showed
that it is only impossible to solve the problem
because it is absolutely wrongly
posed; and that such posing of it is
nothing but the fruit of imagination.
[19] It is
in man that Nature really performs,
in a self-evident way, that
very activity that we are accustomed to call 'thinking'.
In man, in the form
of man, in his person, Nature
itself thinks, and not at all some special
substance, source, or principle
instilled into it from outside. In
man,
therefore, Nature thinks of itself,
becomes aware of itself,
senses
itself, acts on
itself. And the 'reasoning',
'consciousness', 'idea',
'sensation', 'will', and all
the other special actions that Descartes
Pineal Gland
described as modi of thought,
are simply different modes of revealing
a property inalienable from Nature as a whole,
one of its own attributes.
[20] But if thinking
is always an action performed by a natural and so
by a spatially determined body,
it itself, too,
is an action that is also
expressed spatially, which is why there is not
and cannot be the cause
and effect
relation between thinking and bodily action
for which the
Cartesians were looking.
They did not find it for the simple reason that
no such relation exists in Nature,
and cannot, simply because thinking
and the body are two different
things at all, existing separately and
therefore capable of interacting,
but one and the same thing, only
expressed by two different modes or considered in
two different
aspects.
[21] Between body and
thought there is no relation of cause and
effect,
but the relation of an organ (i.e. of a spatially determinate
body) to the
mode of its own action. The
thinking body cannot cause changes in
thought, cannot act on thought,
because its existence as 'thinking' is
thought. If a thinking body does
nothing, it is no longer a thinking body
but simply a body. But when
it does act, it does not do so on thought,
because its very activity is thought.
[22] Thought as
a spatially expressed activity
therefore cannot also
be secreted from the body
performing it as a special 'substance' distinct
from the body, in the way
that bile is secreted from
the liver or sweat
from sweat glands. Thinking is
not the product of an action but the
action itself, considered
at the moment of its performance, just
as
walking, for example, is the mode
of action of the legs, the 'product' of
which, it transpires, is the space walked. And
that is that. The product
or result of thinking may be an exclusively
spatially expressed, or exclu-
sively geometrically stated, change in
some body or another, or else in
its position relative to other bodies.
It is absurd then to say that the one
gives rise to (or 'causes') the other. Thinking
does not evoke a spatially
expressed change in a body but exists
through it (or within it), and vice
versa; any change, however
fine, within that body, induced by the effect
on it of other bodies, is directly
expressed for it as a certain change in
its mode of activity, i.e. in thinking.
[23] The position
set out here is extremely important also because
it
immediately excludes any possibility of
treating it in a vulgar materialist,
mechanistic key, i.e. of identifying
thought with immaterial processes
that take place within
the thinking body (head, brain tissue),
while
nevertheless understanding that thought
takes place precisely through
these processes.
[24] Spinoza was
well aware that what is expressed and performed in
the form of structural, spatial changes
within the thinking body is not at
all some kind of thinking
taking place outside of
and independently of
them, and vice versa (shifts of thinking
by no means express immanent
movements of the body
within which they arise). It
is therefore
impossible either to understand thought
through examination, however
exact and thorough, of the
spatially geometric changes in the form of
which it is expressed within
the body of the brain,
or, on the contrary,
to understand the spatial, geometric
changes in the brain tissue from
the most detailed consideration of the
composition of the ideas existing
in the brain. It is impossible, Spinoza constantly
repeated, because they
are one and the same, only expressed
by two different means.
[25] To try to
explain the one by the other simply means to double the
description of one and the same fact, not yet
understood and incompre-
hensible. And although we have
two full, quite adequate descriptions
of one and the same event, equivalent
to one another, the event itself
falls outside both descriptions, as the
'third thing', the very 'one and the
same' that was not yet understood
or explained. Because
the event
twice described (once
in the language of
the 'physics of the brain' and
once in the language of the
'logic of ideas') can be explained
and
{
definition }
correspondingly' understood only
after bringing out the cause
evoking
the event described but not understood.
{ Example:
to understand LOVE.
}
{
a transcendent
}
[26] Bishop
Berkeley ascribed the cause to
^ God.
And so did
Descartes, Malebranche,
and Geulincx. The shallow, vulgar
materialist
tries to explain everything by the purely
mechanical actions of external
things on the sense organs
and brain tissue, and takes for the cause
the concrete thing, the sole object, that is
affecting our bodily organisa-
tion at a given moment and
causing corresponding changes
in our
body, which we feel within ourselves and experience
as our thinking.
[27] While rejecting
the first explanation as
the capitulation of
{
prejudice }
philosophy before religious
theological twaddle, Spinoza
took a very
critical attitude as well toward
the superficially materialist-mechanistic
explanation of the cause of
thought. He very well
understood that it
was only a 'bit' of
an explanation, leaving in the dark the very difficulty .
that Descartes was
forced to bring in God to explain.
Refuge
of ignorance.
[28] For to
explain the event we call 'thinking', to disclose its effective
cause, it
is necessary to include it in the chain
of events within which
it arises of necessity
and not fortuitously. The 'beginnings'
and the My
italics.
'ends' of this chain are clearly not located
within the thinking body at all,
but far outside it.
[29] To explain
a separate, single, sensuously perceived fact passing
momentarily before our eye, and
even the whole mass of such facts,
as the cause of thought means
to explain precisely nothing.
For this
very fact exerts its effect (mechanical, say,
or light) on stone
as well,
but no action of
any kind that we describe as 'thinking' is evoked in the
stone. The explanation must
consequently also include those relations
of cause and effect that of necessity
generate our own physical organ-
isation capable (unlike a stone)
of thinking, i.e. of so refracting the
external influences and so transforming
them within itself that they are
{
picture
on a panel }
experienced by the thinking
body not at all only as changes arising
within itself, but as external things,
as the shapes of things outside the
thinking body.
[30] For the
action produced on
the retina of our eye by a ray of light
reflected from the Moon is
perceived by the thinking being not simply
as a mechanical irritation within the
eye but as the shape of the thing
itself, as the lunar disc hanging
in space outside the eye, which means
that the Ego,
the thinking substance
or creature, directly feels not the
effect produced on it by the external thing
but something quite different,
viz. the shape or form (i.e.
the spatial, geometric configuration) and
position of this external body,
which has been evoked within us as a
result of the mechanical or light
effect. In that lies both the enigma and
the whole essence of thinking as the mode of
activity of a thinking body
in distinction to one that does not think. It will
readily be understood that
one body evokes a change by
its action in another body; that is fully
explained by the concepts of
physics. It is difficult, and from the angle
of purely physical concepts (and
in Spinoza's time of even 'purely'
mechanical, geometric concepts) even
impossible, to explain just why
and how the thinking body
feels and perceives the effect caused by
an external body within itself
as an external body, as its, and not as its
own shape, configuration, and position in space.
[31] Such was the enigma,
in general, that Leibniz and Fichte
came up
against later—but Spinoza had
already found a fully
rational, though
only general, theoretical
solution. He clearly understood that
the
problem could only be
fully and finally solved by quite
concrete
investigation (including anatomical
and physiological) of the
material
mechanism by which the thinking body (brain)
managed to do the trick,
truly mystically incomprehensible (from
the angle of purely geometric
concepts). But that it did
the trick that it saw the thing and
not the

changes in the particles of the retina and
brain that this body caused by
its light effect
within the brain was an undoubted fact; and a fact calling
for fundamental explanation and
in a general way outlining paths for
more concrete study in the future.
