Philosophy of Knowledge:In Relation to Truth, Knowledge and Metaphysics.
In contemporary
idealism, especially those of Kantian inspiration, knowledge is considered as
the primary and radical philosophical discipline. According to them:
“metaphysics itself must be submitted to the previous judgement of the theory
of knowledge, which would determine whether it is viable or not.”[1]
This sentence could be summarized into this phrase: How can the theory of
knowledge leads us to truth? On the other hand, how can we know that it is
true?
According to a Kantian
metaphor: “reason stands accused before the tribunal in which reason itself is
to be the judge.”[2]
So if our capacity to reason to reach truth is in question, how will we ever be
able to resolve this dilemma?
In a few decades, there
have been many philosophers rejecting knowledge, and considered it as a “dead
letter.”[3]
Heidegger, was one of them who criticized the philosophy of consciousness,
where he denounced the substitution of
certitude for truth[4]
and the consequent interdependence of
reality and its depiction.[5]
Which ends with the ultimate loss of being.
It cannot be like what
Heidegger thinks, because according to Milllan-Puelles:
Gnoseology
can certainly aid us to understand better our knowledge and to correct errors. […]
In fact “the intellectual faculty” is capable of understanding sense knowledge
and, above all, (…) is capable of reflecting on its own acts and deficiencies
of fact; in this sense we use terms like ‘to rethink’, ‘to reconsider one’s
opinion’, ‘to revise our judgements’, etc. However, all of this presupposes
that even if-in fact, and in an accidental way-it is susceptible to error and
deviation, our understanding is essentially apt to attain its proper end.[6]
If not, than it would
be meaningless to attempt to make up for its mistakes, because an understanding
incapable of grasping the truth would never be wrong, no matter how many times
it went over the same ground.
Looking at the
scientific discoveries in the past, and how all the methods and precautions of
science, implies that the fundamental certitude that truth is accessible in some
way. There is a consequence to present knowledge, as the problem of whether or
not truth and certitude can be attained is supreme naïveté, no matter what
attempts it tries to disguise themselves with spectacular criticism. Because if
we are going to doubt our knowing faculty, and to question if it is truly
effective, than it seems to be senseless to try to use it to measure its own
value. All those who adopts this critical position ends up against an
inevitable obstacle: how can we possibly find out if our faculty of knowledge
is ‘valid’ if, in any case, we have to use it to ‘validate’ itself in order to
carry out our investigation?
To clarify truth, will
always be accompanied by the effort to dispel error. As the human intellect is
normally oriented towards truth, but there is a fact that it is limited in some
way, and some occasion, affected by improper moral dispositions of the subject.
These errors affect even the first principles of knowledge.[7]
One example found in
the old Greek, as Aristotle says that, “There are some, who maintain that a
same thing both is and is not.”[8]
This kind of denial of the principle of non-contradiction is even found at
present time, since “the overcoming of contradictions” is one of the basic
elements of Marxist dialectic. It happens, therefore, that throughout history,
the first principles and the most evident truths have been denied or deformed[9] metaphysics,
going deeper into the fundamental certitudes, has proceeded to refute such
fundamental deviations.[10]
Aristotle, the first
philosopher who made a serious and complete balance of the philosophical ideas
developed by his predecessors and contemporaries. In doing so, he comes up
against errors, which affect not only a specific truth, but also the totality
of human knowledge. Some of the sophists, considering man to be “the measure of
all things”, fell into relativism, which led to scepticism: to the paradoxical
thesis that man cannot know truth. Aristotle, in a series of discussions
pointed out with extraordinary acuity, both the internal difficulties of these
theories, which lead to a dead end, and the negative practical consequences,
which they entail.[11]
This defence of the
value of human knowledge does not stop with Aristotle, because throughout a
long process, it develops and enriches by scholars from classical and medieval
philosophy. One example, worth mentioning, are the arguments of St. Augustine
against them sceptics, to whose pretensions of universal doubt, the saint
opposes, among other certitudes, the very existence of doubt: si enim fallor, sum [Even if I err, I
am].[12]
St. Thomas defends the
man’s capacity to know the truth of things, above all against the errors of his
times: logicism, nominalism, Averrorism, etc. He holds to the unity of the
truth, and the distinction and harmony of reason and Faith. He assigns human
knowledge to the place which corresponds too it, as far from exaggerated
rationalism as from a fideism which would deny the value of natural
intelligence. The Gnoseology of St. Thomas Aquinas has the characteristic
features of presenting a metaphysical realism in which being measure knowledge,
and an anthropological realism according to which the human intellect attains
to the truth of real things. This realistic tradition recedes historically into
second place with the rise of the philosophy of consciousness, but its internal
validity has survived the trial for centuries of profound cultural transformation
to this present day.[13]
Altogether, the
broadest and deepest study of the truth, in other words, of true knowledge,
corresponds to metaphysics, as transcendental wisdom. Because, according to
Aristotle saying that: “The consideration of the being in knowledge has a
strict transcendental character, since it refers-in principle-to all of reality
inasmuch as it is-or can be-known by this being which “is, in some measure, all
things.”[14]
Therefore, Gnoseology studies being inasmuch as it is present in the human mind
through knowledge, and inasmuch it is true. Moreover, it does not constitute a
separate and special kind of study of knowledge, but is, rather, properly
metaphysical. Therefore, Gnoseology should be considered as one of the
principal parts pf metaphysics. [15] In other words, it is the metaphysical theory
of knowledge.
According to García
López, saying that
Metaphysics is wisdom,
[…], the supreme science in the natural order; and therefore it cannot
relinquish to any other science the defense or justification of its own proper
principles. The principles on which metaphysics is based are the first
principles of human knowledge attained, however, in their maximum universality
and purity. No other science, apart from metaphysics, can take on the task of
defending these principles. Moreover, it is metaphysics which provides to each
science the most universal principles upon which it is based. To justify its
own principles (showing their evidence and combating contrary reasoning) and to
provide to other sciences the principles upon which they rest, is a mission
which corresponds in full right to metaphysics in its quality as supreme
science.[16]
Gnoseology is the
metaphysics of truth. Its calm study has theoretical importance and vital
relevance. This is true today, because it wards us against fundamental errors,
which are very common now. For millennia, there is a tendency to look upon all
knowledge, especially the knowledge of man.[17]
The value of truth-in-itself comes to be replaced by an approach in which truth
has no meaning, if it has any at all, only as “truth-for-me”. In the face of
this attitude, it is fitting to remember the words of the contemporary poet:
“Your truth? No. the truth,
and come with me to
seek it.
As for your truth…:
keep it.”[18]
The conclusion is that
do discover anew the value of truth, amounts to recovering being as the primary
and original metaphysical value. It comprises, without a doubt, an intellectual
task of great scope and with profound practical consequences.
