I’ve been reading a lot about Idealism in its various forms lately. I know there is already a thread here called: Best arguments for idealism? However, I'm hoping to discuss not just the best arguments for idealism but also the best arguments against it.
I got interested in idealism after discussions here with Hereandnow and Count Lucanor in the “On the nature of religion " thread. I realized that in order to be able to understand Hereandnow’s phenomenology and Count Lucanor’s arguments against it, I would need to understand Idealism because phenomenology is based in Metaphysical Idealism. I have also been doing an online course, along with Chewybrian, in Analytic Idealism. So, I’m waist deep in idealism right now.
But, first, a bit of background. I came to this forum as a dyed-in-the-wool materialist. I thought everything ought to be explicable in terms of matter and energy doing their stuff in space-time, supplemented with the science of evolution to explain the details of life on earth. But being here on this forum has made me think twice about this. I have been driven to explore areas of philosophy which I had once dismissed as mere metaphysical nonsense.
To be clear, what has driven me to explore metaphysics and, in particular, Idealism, is not a lack of belief in the power of science to reveal things that are true about the universe. Nor is it due to a lack of wonder at the universe that science reveals. Far from it. I am gobsmacked when I look at the latest pictures from the surface of Mars and at images from the JWT, and when I consider how a mindless process such as evolution by natural selection can result in “endless forms most beautiful”, and in brains that can begin to understand and wonder at the whole amazing show. If a thinking person is not in awe of what science has revealed about the universe and its workings, then they cannot be thinking clearly. So, no I have absolutely nothing bad to say about science. What has driven me to explore metaphysics is what seems to be a simple truth. Namely, that science, whilst it explains so much and is applicable to everything and anything in respect of the material world, does seem to I come up against a limit beyond which the only recourse seems to be to metaphysics.
Here is an illustration of what I mean by the limits of science.
When I look at the transparent glass paperweight on the desk in front of me and ask what it is, my questioning and answering go as follow: What shape is it? Spherical. What’s it made of? Glass. What is glass made of? Silica, with maybe a of bit of lead and other elements. What are silica and these elements made of? Atoms. What are atoms made of? Well, mostly empty space but there are also protons, neutrons and electrons… And what are they made of? Well, science tells me these particles are made of quarks. And what are quarks? I’m no physicist, but this is where we seem approach some sort of limit. I’ve read that elementary particles are akin to “excitations” in fields of unlimited spatiotemporal extent. But what does that mean? That the whole universe is just mostly empty space with excitations is the fields that pervade it? Ok, well, I can sort of take that on board but what are these excitations and what is space? Mathematical physicists might have some answer to this. But what do those answers look like? They look like equations composed of strings of symbols. And what are those symbols? They are references to features occurring in the mathematical theory, in the mathematical model of the universe. But is the universe just a mathematical model? Just equations? How can this be the case? Those equations are not what I see when I look out at the universe or at my paper weight. They are nothing like the phenomena that are given in consciousness.
As I hope to have made clear, there is an explanatory gap here. Science cannot tell me what the universe is in itself. The best it can do is equations. Therefore, if I want more, I am driven to metaphysical theorizing and the only version of metaphysics that seems to answer is some form of Idealism that posits mind as, if not primary, then at least somehow contributory, in the structure of the universe we see.
Here is how physicist/cosmologist Steven Hawking poses the question: “What is it that breathes fire into the equations and makes a universe for them to describe?”
That is the question.
If I have understood what I have been reading about idealism, there need be no conflict between Idealism and science. One does not seem to absolutely preclude the other. At least, I'm hoping that is the case.
So, everything from materialism to Idealism is on the table for me right now. And that is what I would like to discuss. What are the pros and cons of idealism and of materialism. Need they be mutually exclusive?
