Philosophical Idealism

Bruce Gordon is one of the most brilliant and accomplished thinkers alive today. Among other things he's a historian and philosopher of science and was interviewed recently by another scientist, neurosurgeon Michael Egnor, on a number of topics, including philosophical idealism.

Gordon is one of a growing number of philosophers who find idealism a compelling hypothesis. The interview begins with Dr. Gordon explaining George Berkeley's (1685-1753) version of idealism:

Michael Egnor: What is idealism?

Bruce Gordon: There are a lot of different varieties of idealism, and rather than go through a laundry list of its variations, let me just start with the kind of idealism that I would be an advocate of, which is an ontic theistic idealism, essentially a form of idealism that is probably most closely identified with the Anglican Bishop, George Berkeley.

George Berkeley 1727

Basically, it’s the idea that material substances, as substantial entities, do not exist and are not the cause of our perceptions. They do not mediate our experience of the world.

Rather, what constitutes what we would call the physical realm are ideas that exist solely in the mind of God, who, as an unlimited and uncreated immaterial being, is the ultimate cause of the sensations and ideas that we, as finite spiritual beings, experience intersubjectively and subjectively as the material universe....So we are, in effect, living our lives in the mind of God.

And he is a mediator of our experience and of our inner subjectivity, rather than some sort of neutral material realm that serves as a third thing between us and the mind of God, so to speak.

The discussion then turns for a bit to Plato's notion of idealism as expressed in his theory of Forms.

Plato believed that every particular thing that exists has an ideal essence or form that exists in some abstract realm of reality. Every chair, for example, is recognizable as a chair because it "participates" in the perfect abstract form of "chairness," every tree is recognizable as a tree because it "participates" in the perfect form of "treeness."

Likewise with everything, including humans.

Later Christian Platonists argued that these essences, or forms, or ideals existed not in some abstract realm but rather as ideas in the mind of God, and this, it seems, is Gordon's view as well.

Michael Egnor: There are, I believe, other kinds of idealism. For example, idealism by German philosophers. And how does that differ from Berkeleyan idealism?

Bruce Gordon: Well, .... [Immanuel] Kant (1724-1804) advocated a kind of epistemic, as opposed to ontic, idealism. Kantian idealism is entirely compatible with the existence of material substances, even though they are inaccessible as things in themselves.

So for Kantian idealism, you’ve got a self that .... precedes and grounds all of our experience. And our perception of reality, then, is governed by the innate structure of the human mind.

Immanuel Kant 1768 

What Gordon is saying here is that Kant believed that a material world existed but that everything we know about it is based on our sensory perceptions which produce ideas or sensations in the mind. Our mind is so structured as to create these ideas, but the ideas may be nothing at all like the thing they represent.

In other words, what we know about the "thing in itself" is the sum of the ideas (or sensations) we have of it in our minds. We can't know it as it exists independently of our perceptions of it.

For example, our minds, upon seeing, smelling and tasting chocolate, generate the ideas of a certain color, fragrance and flavor, but these ideas are in our minds, they're not in the chocolate. The chocolate itself doesn't have color, it simply reflects certain wavelengths of light. Likewise, it doesn't have fragrance or flavor. It simply exudes chemicals which interact with our senses to produce the ideas of fragrance and flavor in our minds.

As Kant put it, “You only know me as you see me, not as I actually am."

Bruce Gordon: So we never experience reality in itself, which he called the noumenal world, but only reality as it appears to us, a ... phenomenal reality that is ordered by the innate structures of the human mind.

Kantian idealism and its descendants are, in many ways, an epistemic form of idealism, whereas the Berkeleyan form of idealism is ontic.

By this Gordon means that Kant's idealism had to do with what we can know about the world whereas Berkeley's idealism had to do with the ontology of the world - what was actually real and what reality was like. Gordon adds:

[Berkeley's Idealism is] a denial that there is material substance and [is instead] an embedding of reality in the mind of God, such that it is finite spiritual beings experiencing the reality brought into existence by this unlimited, uncreated, immaterial being.

Berkeley's idealism, then, was different from Kant's. Berkeley held that there was no material world at all. Everything we experience we experience as ideas in our minds, ideas which are presented to our minds by the mind of God.

As Berkeley himself says, “All the choir of heaven and furniture of earth — in a word, all those bodies which compose the frame of the world — have not any subsistence without a mind.” This may seem bizarre at first reading, but according to the Stanford Encyclopedia of Philosophy “Berkeley’s system, while it strikes many as counter-intuitive, is strong and flexible enough to counter most objections.”

It's interesting that in the last fifty years or so many physicists have embraced idealism. They're persuaded by developments in quantum mechanics that reveal that at the subatomic level many properties of the entities scientists study at that level don't exist until they're observed.

For instance, the 20th century scientist Max Planck, often called the father of quantum mechanics, once stated that,

As a man who has devoted his whole life to the most clear headed science, to the study of matter, I can tell you as a result of my research about atoms this much: There is no matter as such. All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration and holds this most minute solar system of the atom together.

We must assume behind this force the existence of a conscious and intelligent mind. This mind is the matrix of all matter.

And Sir James Jeans, in his book The Mysterious Universe, wrote that, "The universe is beginning to look more and more like a great thought rather than a great machine."

Idealism has considerable intellectual appeal for quantum physicists (and increasingly for biologists and cosmologists), but I should think it would also be attractive to some thoughtful theologically oriented folks since the doctrine conforms nicely to the conviction that the reality we experience is fundamentally a projection of the mind of God.

The Worst Persecution Most People Have Never Heard About

While Americans fret over the deaths of Palestinian Muslims and the Trump administration promises to make Muslim Iran "Great Again," Muslims are continuing to be responsible for perpetrating the worst atrocities in the 21st century. According to Global Christian Relief,

Nigeria has become known as the world’s center of Christian martyrs. In any given year, the number of Christians killed by extremist groups is rarely less than 4,000—often more than in the rest of the world combined.

Violence against the Nigerian Christian population is significantly localized in the north, where twelve Muslim-majority states declared sharia law in 1999, resulting in huge numbers of Christians experiencing daily discrimination. But it was the rise of an extremist movement called Boko Haram, which first started its murderous attacks in 2009, that resulted in Christians experiencing unprecedented violence.

According to an April 2023 report by the International Society for Civil Liberties and Rule of Law, at least 52,250 persecuted Christians have been killed in the past fourteen years, simply for the crime of being Christian. In the past five years, violence has spread southwards to the middle belt of Nigeria, with radicalized Fulani herdsmen killing Christians to steal their land.

Boko Haram has now been joined by another extremist group operative in the area, called the Islamic State West Africa Province (ISWAP), and both seek the eradication of Christianity from the northern states.

The violence has resulted in refugees now numbering over four million, mostly Christian farmers. The government of Nigeria has proved unwilling to condemn the levels of violence, which some call genocidal, or inept in its attempts to engage and neutralize extremist movements.

This is a staggering report. While the Trump administration promises billions to Iran and Gaza, Nigerian Christians, who have done nothing to offend the Muslims who hate them, suffer in poverty and fear at the hands of terrorists who have been supplied and abetted by Iran.

No doubt were Muslims being slaughtered by Christians or Jews for no reason other than that they were Muslims, our campuses, and indeed the world, would be in a state of volcanic outrage.

As it is, since it's Christians who are being killed by Muslims, and black Christians at that, the world just yawns.
