A priori is that before the senses.
A posteriori is that after the senses.
Seems vague.
'Sense' is to be limited to sense organs and their respective neural elements.
What about sense data, perception, cognition, consciousness, experiences that result from the triggering of the sense organs.
Vague is a subjective viewpoint.
It is my great campaign in ontology to take the vague and the indefinite out of the realm of the subjective and make it real and objective. Indeed, in my ontology there is no subjective realm. Everything I experience is real.
I also disagree with you when you say that 'sense' is limited to sense organs and their respective neural elements. So-called secondary qualities, such as color and fragrance and sound are just as real and objective as anything else. That is my extreme realism. I follow the New Realists of a century ago.
John Passmore, in his book A Hundred Years of Philosophy, wrote:
"The first, in England, to formulate the characteristic doctrines of the New Realism was T.P. Nunn. Best known as an educationalist, Nunn wrote little on philosophy, but that little had an influence out of all proportion to its modest dimensions. In particular, his contribution to a symposium on ‘Are Secondary Qualities Independent of Perception?” was widely studied both in England where, as we have already noted, it struck Bertrand Russell’s roving fancy, and in the United States. Nunn there sustained two theses: (1) that both primary and the secondary qualities of bodies are really in them, whether they are perceived or not: (2) that qualities exist as they are perceived.
Much of his argument is polemical in form, with Stout’s earlier articles as its chief target. Stout had thought he could begin by presuming that there are at least some elements in our experience which exist only in being perceived – he instanced pain. But Nunn objects that pain, precisely in the manner of a material object, presents difficulties to us, raises obstacles in our path, is, in short, something we must reckon with. ‘Pain,’ he therefore concludes, ‘is something outside my mind, with which my mind may come into various relations.’ A refusal to admit that anything we experience depends for its existence upon the fact that it is experienced was to be the most characteristic feature of the New Realism.
The secondary qualities, Stout had also said, exist only as objects of experience. If we look at a buttercup in a variety of lights we see different shades of colour, without having any reason to believe that the buttercup itself has altered; if a number of observers plunge their hands into a bowl of water, they will report very different degrees of warmth, even although nothing has happened which could affect the water’s temperature. Such facts demonstrate, Stout thought, that secondary qualities exist only as 'sensa' – objects of our perception; they are not actual properties of physical objects.
Nunn’s reply is uncompromising. The contrast between ‘sensa’ and ‘actual properties’ is, he argues, an untenable one. All the shades of colour which the buttercup presents to an observer are actual properties of the buttercup; and all the hotnesses of the water are properties of the water. The plain man and the scientist ascribe a standard temperature and a standard colour to a thing and limit it to a certain region of space, because its complexity would otherwise defeat them. The fact remains, Nunn argues, that a thing has not one hotness, for example, but many, and that these hotnesses are not in a limited region of space but in various places around about the standard object. A thing is hotter an inch away than a foot away and hotter on a cold hand than on a warm one, just as it is a paler yellow in one light than it is in another light. To imagine otherwise is to confuse between the arbitrary ‘thing’ of everyday life and the ‘thing’ as experience shows it of be.
In Nunn’s theory of perception, then, the ordinary conception of a material thing is revolutionized; that is the price he has to pay for his Realism. A ‘thing’, now, is a collection of appearances, even if every appearance is independent of the mind before which it appears."
