Things are individuated. The p=q is not a truth. Categorically, this can be true. Realistically, p is p and q is q.
Unless a concept is turned into an object – a noun – we cannot talk about it. We cannot escape the the idea of it being an “it”. Notice the countability of “it”. This move or ability to convert a concept into a countable, tangible thing is one of the most powerful and useful tools to us – the human being. It defines us and at times separates us from other beings. So much so, that it may elevate us about gods or even God. This is not a new idea. Nietzsche had said so much with the phrase “God is dead”. But let us go further and talk about what it is like where God may be talked about in the past tense, to be able to talk about a time when God was alive. The fact that God was, is and will be yet is only ever discussed in terms of the present or presence (as it were) should set off critical and philosophical alarm bells. Fundamentally, we must see through the power (and weakness) of language which had once moved us forward but is now holding us back.
There is an excellent account of the word “nature” in Raymond Williams’ book Keywords: A Vocabulary of Culture and Society (page 219). Three definitions of the word were listed.
- the essential quality and character of something
- the inherent force which directs either the world or human beings or both
- the material world itself, taken as including or not including humans beings
Example sentences of these respectively could be, for example:
- “The nature of the crime was too gruesome to describe.”
- “Nature will dictate our planet’s future.”
- “Man and nature have achieved harmony.”
While the oldest usage is that 1 it is used more now as 2 and 3 where differentiation is difficult between the the latter two. What is important is the inclusion and exclusion of human beings. One is to equate nature with God with a capital G (as noted by Williams). Thus 3 is close to the physical reality when man is included, but only the natural world apart from human being and human culture.
Personally, I believe nature includes us (meaning 3). Nature made us to develop ideas which includes ideas about God, nature, and culture. There is a role for the idea of exclusion as well as inclusion. We have the capacity to think and express either. The ground of battle is not in God, nature, or culture but the nature* of language itself.
*First meaning was meant and unavoidable.
There are things. And there are processes of things. The epistemological process of a body-thing is conceptualisation. The communicative/functional process of a body-thing is symbolisation. Let us label these meaning-structure words referent, concept, and symbol respectively.
The above diagram is the standard Ogden/Richard triangle of reference.
But it is possible to have:
- a referent with a concept and symbol for it;
- a referent with a concept but without a symbol for it;
- a referent without a concept or symbol for it;
- a concept without a referent or symbol for it, and;
- a concept with a symbol for it.
The symbol for a referent-less concept in (5.) is substituted for its referent. And it is here that often our understanding of the world breaks down.
For example, the process of invention usually begins with the conceptualisation something which does not exist (study case: iPhone). Eventually this is given a name and the physical product of the iPhone is manufactured and the referent iPhone is brought into existence. In other cases this creation process may not be possible (study case: Harry Potter). The only way it is brought into being is through the process of literature (writing and publishing a novel). Harry Potter only exists as a character in a novel, and not as a person as such. In this sense Harry Potter remains in (5.) never to become a real thing as in (1.). Only fiction about Harry Potter in the form of physical novels becomes (1.).
A is a because it is not b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, or z.
B is b because it is not a, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, or z.
C is c because it is not a, b, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, or z.
And so on until z.
A does not have an inherent meaning, only meaning because it differs to the other symbols. And by not having an inherent meaning it defers meaning. This is what Derrida had meant by differance. The choice of a different letter but identical pronunciation was to highlight differing, deferring and difference. The implication is that nothing has meaning present unto itself, only meaning via absence. He terms the mistake to think otherwise metaphysics to presence.
George Lakoff and Mark Johnson’s important work Metaphors We Live By pointed out an aspect of conceptualisation and language – that we must resort literal physical meanings and relationships in order to talk about the abstract.
The employment of metaphors of the real is the only way we can talk about unreal.
Consider these sentences.
- He is in the kitchen.
- The concert starts in three hours.
- She is in the choir.
- They are in love.
All sentences employ spatial relation “in” to describe the concepts.
But only 1 is literal or real. Both “he” and “the kitchen” are real things. The person is located in a space. In 2 uses space to talk about time. And 3, and 4 use space to talk about membership and emotional state. While it can be argued that one can use non-space to describe things, it is neither easy, economical, nor natural. In other words, abstract or unreal concepts simply cannot be mentally, psychologically or conceptually manipulated without recourse to the real literal world.
“There is a book on the table. The book is brown. I will accept the book exists. But does the colour brown exist?”
Brown is a wavelength. White light bounces off the book. The characteristics of the book absorb certain wavelengths. What is not absorbed is reflected. Let us call this isolated, reflected wavelength (low-intensity light at 600 nanometres) which reaches our eyes “brown”. The eyes, which are receptive to wavelengths, transmits that information from the retina down the nerves to the brain where it is equated to “brown”.
You see the book. I see the same book. The colour which is reflected corresponds to “brown” in your vocabulary and my vocabulary. But whether we see the same colour in the same manner does not matter. As long as we are talking about the same “thing” is all that is important.
In this sense, we have isolated the property “brown” to be the wavelength and given it this agreed-upon name. The wavelength exists as light, as energy. I would say “yes”, it physically exists.
