There is no distinction. — Garrett Travers
For a biologist there may be no distinction, because he's interested in mechanisms, not functions. But for psychologists and philosophers, the meaning in a mind is the "difference that makes a difference".
No, photons have mass, what are you talking about? Light and energy are material forces. — Garrett Travers
Photons only have mass when they slow down and transform into matter. Besides,
Mass is not a material object, but a mathematical function otherwise known as "inertia". It's defined as a "property" of matter, but not as matter per se. A property is a mental attribution, a thought.
Energy-in-general likewise transforms into mass only when it slows from lightspeed into velocities our senses can detect. They are different forms of the same fundamental force, which is neither light nor matter, but the potential for both. Their distinct measurable properties are how scientists distinguish between each form and give it a special name. For example, an electron is intermediate between photon and matter. Hence, deserves its own designation.
Unfortunately, Mind & Thought have no measurable properties apart from their associated material or energetic forms. Their existence must be inferred indirectly.
What is Mass? :
mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force.

"But, the function of a machine is "non-physical", so we can't see it, and only know it by what it does" — Gnomon
No. You need to brush up on cog-sci, this is an utterly unscientific assertion. Yes, we can see it through functional mri. — Garrett Travers
That assertion is a category error. It confuses the function of an MRI machine --- to display the Effects of a magnetic field on the iron molecules in blood --- with brain functions. MRI images require a human Mind to interpret that feedback in terms of malfunctions. :worry:
Yep, and they were wrong, all of them. I wish I could say it to their faces. — Garrett Travers
It's too bad that you can't argue with dead white men. But you could in theory tell Neurobiologist Christof Koch that he's wrong about The Feeling of Life Itself.
The "feeling" he refers to is not a physical object, or a neuronal computation, but something else entirely. He calls it a "hack", but it's essentially an emergent Quality, which can't be measured, but can be experienced. He even toys with the notion of Panpsychism (i.e. widespread). Is he "wrong", in your expert opinion? You could suggest that he "brush-up on cog-sci".

The thoughts are in fact the functions. There are no "thoughts," just computations which are observed through executive function, another brain function. — Garrett Travers
A "function" is a mathematical concept, not a tangible object. See the Koch quotes above & below for his opinion on thoughts as computations. In what sense is a computation a material thing?
Confessions of a Romantic Reductionist :
What links conscious experience of pain, joy, color, and smell to bioelectrical activity in the brain? How can anything physical give rise to nonphysical, subjective, conscious states? . . .
In which I muse about final matters considered off-limits to polite scientific discourse: to wit, the relationship between science and religion, the existence of God, whether this God can intervene in the universe, the death of my mentor, and my recent tribulations

That's because that which does not exist leaves no evidence of itself having not existed, except the absence of evidence existence itself. — Garrett Travers
You, perhaps deliberately, missed the point of "non-physical existence". If ideas & thoughts are experienced in your reality, then they have an existence of some kind. It's just a question of labeling.
Consciousness researchers refer to "ideas", not as material things, but as immaterial "representations" of both objective things and subjective thoughts. Long after the idea or feeling is gone, we can recall then in the form of Memories, which are also subjective Thoughts.
Representationalism :
philosophical theory of knowledge based on the assertion that the mind perceives only mental images (representations) of material objects outside the mind, not the objects themselves.

"Immortality, we can only argue its existence by comparing
opinions & beliefs." — Gnomon
We actually can't even do that. — Garrett Travers
If you can't compare opinions and beliefs, what are we doing on this forum? Are we teleporting physical objects over cyber-space?
Everything but Strings, yes. The domain of ideal existence exploration is here, right here on earth, — Garrett Travers
Are you denying the existence of "Strings" & "Loops". You may not be able to see them, even in principle, but the idea of such entities certainly "exist" as thoughts or feelings in the functioning minds of earth-bound mathematicians.
They don't attempt to prove their existence empirically, but merely ask you to take it on faith, until they are eventually able to use the power of Strings to cause changes in the real world. Meanwhile, their only evidence is long strings of abstract numbers & symbols that are intended to "represent" unseen things. :joke:
