Materialism is the recognition of "objects in themselves", or outside the mind; ideas and sensations are copies of images of those objects.

What we call objective reality is, in the last analysis, what is common to many thinking beings, and could be common to all; this common part, we shall see, can only be the harmony expressed by mathematical laws. It is this harmony... which is the sole objective reality, the only truth we can attain; and when I add that the universal harmony of the world is the source of all beauty, it will be understood what price we should attach to the slow and difficult progress which little by little enables us to know it better.

Reality contains matter and non-matter

The ontology of materialism rested upon the illusion that the kind of existence, the direct 'actuality' of the world around us, can be extrapolated into the atomic range. This extrapolation, however, is impossible... Atoms are not things.

We now know too much about matter to be materialists. The very essence of the physical order of things is that it creates nothing new. Change is never more than a redistribution of that which never changes. But sensibility belongs to the world of consciousness, not to the world of matter.

It is this harmony then which is the sole objective reality, the only truth we can attain; and when I add that the universal harmony of the world is the source of all beauty, it will be understood what price we should attach to the slow and difficult progress which little by little enables us to know it better.

To be a materialist is to acknowledge objective truth, which is revealed to us by our sense organs.

[Materialism] seeks the primary and most simple state of matter, and then tries to develop all the others from it; ascending from mere mechanism, to chemism, to polarity, to the vegetable and to the animal kingdom. And if we suppose this to have been done, the last link in the chain would be animal sensibility - that is knowledge - which would consequently now appear as a mere modification or state of matter produced by causality. Now if we had followed materialism thus far with clear ideas, when we reached its highest point we would suddenly be seized with a fit of the inextinguishable laughter of the Olympians. As if waking from a dream, we would all at once become aware that its final result - knowledge, which it reached so laboriously, was presupposed as the indispensable condition of its very starting-point, mere matter; and when we imagined that we thought matter, we really thought only the subject that perceives matter; the eye that sees it, the hand that feels it, the understanding that knows it. Thus the tremendous petitio principii reveals itself unexpectedly.

3. Mathematical objects do not exist in a mysterious Platonic heaven totally independent of the physical world. Rather, physical reality is a mental interpretation of a subset of mathematical structure.

A clear objective perception of facts, and the laws and principles which inhere in facts, is a moral, no less than a mental quality. It implies a purification of the character from egotism and pride of opinion, a rare union of humility of feeling with audacity of thought, and, above all, the triumph of a sincere love of objective truth over the desire to exalt a subjective self.

This was the true nature of consciousness and the meaning of matter, that ultimately both were one substance without cause or control outside itself.

Materialism lives outside the lines of my reality

All that matters is the pleasure-pain axis. Pain and pleasure disclose the world's inbuilt metric of (dis)value. Our overriding ethical obligation is to minimise suffering. After we have reprogrammed the biosphere to wipe out experience below "hedonic zero", we should build a "triple S" civilisation based on gradients of superhuman bliss. The nature of ultimate reality baffles me. But intelligent moral agents will need to understand the multiverse if we are to grasp the nature and scope of our wider cosmological responsibilities. My working assumption is non-materialist physicalism. Formally, the world is completely described by the equation(s) of physics, presumably a relativistic analogue of the universal Schrödinger equation. Tentatively, I'm a wavefunction monist who believes we are patterns of qualia in a high-dimensional complex Hilbert space. Experience discloses the intrinsic nature of the physical: the "fire" in the equations. The solutions to the equations of QFT or its generalisation yield the values of qualia. What makes biological minds distinctive, in my view, isn't subjective experience per se, but rather non-psychotic binding. Phenomenal binding is what consciousness is evolutionarily "for". Without the superposition principle of QM, our minds wouldn't be able to simulate fitness-relevant patterns in the local environment. When awake, we are quantum minds running subjectively classical world-simulations. I am an inferential realist about perception. Metaphysically, I explore a zero ontology [...] the total information content of reality must be zero on pain of a miraculous creation of information ex nihilo. Epistemologically, I incline to a radical scepticism that would be sterile to articulate. Alas, the history of philosophy twinned with the principle of mediocrity suggests I burble as much nonsense as everyone else.

Material phenomenology is able to designate this invisible phenomenological substance. It is not a nothing but rather an affect, or put otherwise, it is what makes every affect, ultimately every affection, and every thing possible. The phenomenological substance that material phenomenology has in view is the pathetic immediacy in which life experiences itself. Life is itself nothing other than this pathetic embrace and, in this way, is phenomenality itself according to the how of its original phenomenalization. Life is thus not a something, like the object of biology, but the principle of every thing. It is a phenomenological life in the radical sense where life defines the essence of pure phenomenality and accordingly of being insofar as being is coextensive with the phenomenon and founded on it. For what could I know that could not appear ?
