My
continuing journey towards the writing of identity has led me into a quagmire
of ideas and thoughts. I confess this, not in the sense of a bad situation, but
more in the sense of a fertile marshland, a sort of Everglades of cogitation.
The
Aristotelian approach is contained in the first of his three classic laws of
thought, i.e. the law of identity. It states that an object is the same as
itself: A → A (if you have A, then you have
A). While this can also be listed as A ≡ A
(A is equivalent to A), this is redundant. Any
reflexive relation upholds the law of identity. When discussing equality, the
fact that "A is A" is a tautology.
In mathematics, a reflexive relation is a binary
relation on a set for which every element is related to itself. In other words,
a relation ~ on a set S is reflexive when x ~ x holds true
for every x in S. An example of a reflexive relation is the
relation "is equal to" on the set of real numbers, since every real
number is equal to itself. A reflexive relation is said to have the reflexive property.
A binary relation on a set A is a
collection of ordered pairs of elements of A. In other words, it is a
subset of the Cartesian product A2 = A × A.
More generally, a binary relation
between two sets A and B is a subset of A × B.
The terms dyadic relation and 2-place relation are synonyms for
binary relations
In logic, a tautology (from the Greek word ταυτολογία) is a formula which is
true in every possible interpretation.
So
when I contemplate a quagmire of ideas and thoughts, I am contemplating
identical things: A/idea = A/thought. The
process of thinking perceives thoughts and as Goethe stated “Thinking is no more and no less an organ of
perception than the eye or ear. Just as the eye perceives colours and the ear
sounds, so thinking perceives ideas.” But is this swamp a reality, a
tangible thing? I would say yes, but
some would argue no.
Arthur Schopenhauer discussed the laws of thought and tried
to demonstrate that they are the basis of reason. He listed them in the
following way in his Über die vierfache Wurzel des Satzes vom
zureichenden Grunde (On the Fourfold Root of the Principle of Sufficient
Reason), §33:
•
A subject is equal to the sum of its
predicates, or a = a.
•
No predicate can be simultaneously
attributed and denied to a subject, or a ≠ ~a.
•
Of every two contradictorily opposite
predicates one must belong to every subject.
Truth
is the reference of a judgment to something outside it as its sufficient reason
or ground.
Thus;
•
Everything that is, exists.
•
Nothing can simultaneously be and not
be.
•
Each and every thing either is or is
not.
•
Of everything that is, it can be found
why it is.
There
would then have to be added only the fact that once for all in logic the
question is about what is thought
and hence about concepts and not about real things.

Schopenhauer,
Manuscript Remains, Vol. 4, "Pandectae II," §163
To show that they are the foundation of
reason, he gave the following explanation:
Through a reflection,
which I might call a self-examination of the faculty of reason, we know that
these judgments are the expression of the conditions of all thought and
therefore have these as their ground. Thus by making vain attempts to think in
opposition to these laws, the faculty of reason recognizes them as the
conditions of the possibility of all thought. We then find that it is just as
impossible to think in opposition to them as it is to move our limbs in a
direction contrary to their joints. If the subject could know itself, we should
know those laws immediately,
and not first through experiments on objects, that is, representations (mental
images).
Schopenhauer(On the
Fourfold Root of the Principle of Sufficient Reason), §33:
Schopenhauer's four laws can
be schematically presented in the following manner:
•
A
is A.
•
A
is not not-A.
•
A
is either A or not-A
•
If
A then B (A implies B)
I would argue that thoughts are real
things. The fact that they can be spoken, written, read, in short, perceived,
makes them real.
Aristotle wrote:
Now
"why a thing is itself" is a meaningless inquiry (for—to give meaning
to the question 'why'—the fact or the existence of the thing must already be
evident—e.g., that the moon is eclipsed—but the fact that a thing is itself is
the single reason and the single cause to be given in answer to all such
questions as why the man is man, or the musician musical, unless one were to
answer, 'because each thing is inseparable from itself, and its being one just
meant this.' This, however, is common to all things and is a short and easy way
with the question.) -
Metaphysics, Book VII, Part 17
So you see the quandary. How did I get
into this problem of writing identity? Here's a little ditty about thinking:
