The Observer

Perspectivalism has me looking for thirds to every old dichotomy. There is a perceiving subject for every fact/value distinction, and a moral actor who decides between deontology and teleology. Frame and Poythress articulate this triad as "subject, object, norm."

Who is this "subject"? Does the "subject" really make any difference to what we know and do? Is the "subject" important enough to sit side-by-side with physical reality and natural law?

Rene Descartes brought the "subject" into the center of this philosophy when he said, "I think, therefore I am." The observing self provided the first fact for Reason (the norm), which used it to deduce Reality (the object).

Descartes left the "subject" behind once he got his feet on the familiar ground of philosophy, but his younger contemporary Blaise Pascal had more interest in the "subject." Pascal, who said, "The heart has its reasons of which reason knows nothing," is often claimed as a forefather of existentialism.

I'm not ready to write about existentialism yet--although I delight in the great "Christian existentialists" (Pascal, Kierkegaard, and Dostoevsky), I could never force myself to take existentialism itself seriously before Frame and Poythress showed me how. So let me jump to something that I actually believe in--quantum physics.

In the weird world of quantum physics, what we think of as "reality" is arguably less real than the observing self. Twenty-first century scientists believe the laws of physics govern time, space, matter, and energy, but this does not result in a single predictable world. Instead, physical realisty and natural law produce a "wavefunction of the universe" which includes all possible worlds. The "actual world" that you and I observe is a collapsed subset of that wavefunction. Most quantum physicists say the act of observation causes the wavefunction of possibility to collapse into any one actuality.


Who is this Observer? Does the subject matter? And should I master existentialism or quantum physics to find out?

I feel like Odysseus, sailing between Scylla on one side and Charybdis on the other.

But if Truth lies on the other side, I must sail on...

What is Perspectivalism?

What Is Perspectivalism?

"Perspectivalism" is a post-modern way of thinking about thinking that has been articulated by Vern Poythress and John M. Frame. Frame's brief Primer on Perspectivalism outlines the method.

Frame starts by observing that every (human) act of knowing takes place from some limited perspective. Recognizing this makes us more humble about the extent our own knowledge and more eager to increase it.

One way to increase our knowledge and our level of certainty is by supplementing our own perspectives with those of others. When our own resources fail us, we can consult friends, authorities, books, etc. We can travel to other places, visit people of other cultures. Even to get a good understanding of a tree, we need to walk around it, look at it from many angles.

It often happens that someone’s idea will seem ridiculous when we first encounter it; but when we try to understand where that person is coming from, what considerations have led him to his idea, then our evaluation of it changes. In such a case, we are trying to see the issue from his perspective, and that perspective enriches our own.

Perspectivalism Is Not Relativism

Perspectivalism seems safer than absolutism and wiser than relativism. Friedrich Nietzsche captured the core of relativism in The Will to Power:
There are many sorts of eyes. The sphinx too has eyes; consequently, there are many sorts of "truths," and consequently there is no truth. (Will to Power, section 540)
Perspectivalism does not confuse the blind stone eyes of the sphinx with the many sorts of eyes that really see.

Perspectivalism Is Not Absolutism

Perspectivalism is not absolutism because it does not confuse any (finite) individual's ideas with "Truth." This is not to say that Frame and Poythress deny the existence of absolute truth--they are both theology professors (Poythress is at Westminster Theological Seminary in Philadelphia, Frame is at Reformed Theological Seminary near Orlando). Perspectivalism distinguishes between the finite perspective of any created being with space and time, and the ultimate perspective of the Creator of space and time.

The Power of Perspectivalism

This humble but hopeful theory of knowledge could be a breakthrough in epistemology (which seems to have fallen on hard times recently). It could also provide a "grand unified theory" of ethics, by fusing deontology, teleology, and existential ethcs.
