Thinking
There are quite a few authors and
researchers today who say that our self-awareness is an illusion.
They say that a critical mass of advanced human brain neurons and
cultural mental tools such as language and mathematics co-evolved to
produce a sense of self.
I thought it might be helpful to share
a kind of intellectual “selfie” about my mistakes in thinking
about consciousness and the immaterial or spiritual. Fr. Conrad
Dietz, a professor of Metaphysics and Epistemology, once told his
students that it is most difficult to think abstractly. In other
words, not just to use images but to think. Ironically, most, if not
all, my mistakes in thinking about consciousness and the immaterial
was a failure to think abstractly.
When I was teaching high school
religion in the 1980's I wanted to give some “proof” to my
students of a non-material or spiritual aspect to human life. They
were asked to imagine a picture. Then I declared that no chemical or
surgical process could “find” that picture in their brain. I was
wrong.
The image we call to mind is as physical as the object
imagined. If you dissect a computer's memory storage you will not see
the images stored. If you have the right connection to a display
monitor you will see the image. Research with brain imaging
techniques such as MRIs detail how certain areas of the brain become
active in correspondence to an image. As an aside, with this type of
investigation, they have discovered that so-called vegetative
patients can communicate by thinking of an image.
Having realized what St. Thomas Aquinas
already taught in the 1200's (memory is physical), I tried to refine
my example. Confidently admitting my earlier teaching error, I
proposed a new comparison. On one hand, here is a computer and a
monitor that is displaying an image. On the other hand, once more
call to mind a picture. Different equipment but a comparable result.
Then I delivered the mental “punch line”: Who is looking at the
image on the monitor or who is looking at the picture in your brain?
A subject must be viewing the images.
I mentioned my new improved image to
Charles DeCelles, a retired professor from Marywood University in
Scranton, Pennsylvania. His response was basically that yes, we call
something to mind AND THEN WE THINK ABOUT IT. Slowly, I realized that
he had freed me from an illusion.
Do not animals see images displayed by
the optic nerve? (I am reminded of another foolish forgetting of
basic Catholic wisdom, again back in my 1980's teaching. A young
student said animals have souls. I defensively jumped to the
conclusion that she was elevating animals to the moral level of human
life – which some people do – and I quickly answered that they
did not. Yet Catholic theologians have held that animals do have
souls – a mortal physical soul that ceases by death.) Professor
DeCelles threw me back to my earliest training by Professor Dietz –
we must think abstractly.
As humans we experience with our senses
but we think about the universe with our intellect. Cats and humans
can both be physically awake or conscious. Consciousness is not the
same as thinking. Self-consciousness or self-awareness differs from
merely being awake. And self-awareness is necessary for the process
that you are now engaged in – reflection. And self-reflection is
necessary for what I hope we are now engaged in – thinking.
Thinking is not calling images to mind or even the review of past
experience. Thinking occurs when we abstract from experience to
arrive at a principle. If someone says that there is no intellect and
free will in Man then they are using that intellect to abstract a
principle.
Our spiritual intellect and free will
depends on the body for information and mental tools. But as
spiritual we can make a judgment about reality and a resolution to
act according to that judgment. In City of God, book XI, #26 (italics mine) St.
Augustine not only dismisses doubt about our existence but affirms
our individual soul: “But, without any delusive representation of
images or phantasms, I am most certain that I am, and that I know and
(I) delight in this. In respect of these truths, I am not at all
afraid of the arguments of the Academicians who say, What if you are
deceived? For if I am deceived, I am... And, consequently, neither am
I deceived in knowing that I know. For, as I know that I am, so I
know this also, that I know. And when I love these two things, I add
to them a certain third thing, namely, my love which is of equal
moment.”
