Seria Musings #4

Let us begin by making an addendum to the third entry in this series of posts: the thresholds pertaining to each identity being unique on a case by case basis is not something bad, on the contrary, it is good, because it is a guarantee that two things will only be the same if they are, in fact, one and the same thing. This can be backwards posited with a threshold to determine the notion of equality or identity. (In this way, the very notion of identity or equality itself can be defined.)

Now, continuing our topic: on Tractatus Logico-Philosophicus, fifth item, Wittgenstein says that: "A proposition is a truth-function of elementary propositions. (An elementary proposition is a truth-function of itself.)"

Therefore, it seems we are pursuing a more or less accurate trail. There must be, then, some approximation between a logic of becoming, a logic of being, category theory and, perhaps, because it seems to approach category theory, a type theory. But to account for this multiple approach, we would need a mathematical finesse that does not belong here.

It is important to note that a process-based approach will not hinder the emergence of emergent structures.

In this way it is possible to stipulate a rich and complex reality without ignoring the explanatory advances of the sciences, avoiding patently unreasonable eliminativism and reductionism, yet parsimoniously giving an account only of what in fact exists, without a useless ontological anarchic proliferation. Thus, for example, the intentionality of conscious experience can be composed as a fitting of functions that are irreducible to each other.

According to field theory, as well as the gunk nature of time (i.e., something infinitely divisible), it seems that reality is based on interactions. The interpretative key here is in the gunk nature of time: continuous in such a way that it can be infinitely divisible, but for all practical purposes it reaches a threshold which, for us, is small enough, that is, it suffices. (To understand the gunk nature, think of the real number line: we can zoom indefinitely and the results keep showing up.) Making yet another analogy: the point (in the sense of Euclidean geometry) would be only a regional compacting whose threshold is infinitely small.

So, to follow the line of reasoning that is emerging here, we would say that identity (in a sense similar to the strict sense of mathematical equality) is only a case of similarity whose threshold is sufficiently restricted (perhaps infinitely restricted); and, more appropriately and more generally: identity is a differentiation of null (or at least negligible) intensity. To add another analogy: it would be like considering silence as just null intensity sound.

Thus, we do not need to give in to the onticological principle (i.e. there is no difference that does not make a difference, viz., every difference makes a difference) nor, in a broader sense, to flat ontologies (which, most often, are patently false) – simply because there are affectation thresholds: not everything will always affect everything else. In this way we are preserving hierarchized ontologies without, however, establishing concepts with unnecessary internal constraints. We gain flexibility and possibility without losing scientificity.

Moreover, if we wanted to be Humeans to the fullest, we could establish reality itself as based on varying ranges of thresholds of possibilities of existence. It would be an easy way out and would make reality in itself inductive, but it remains – forgive the pun – a possibility (of explanation).

  1. In terms of possibilities, I recall having read somewhere - it *might* have been in Brian Greene's 'Fabric of the Cosmos', but quote me neither on the source nor on the content - that strictly speaking, entropy is not a one-way street. In other words, there is a nonzero possibility that, once you open a bottle of cola, all the escaping carbon dioxide molecules will gather themselves back into the bottle. However, the possibility is so infinitesimal, that we simply don't give it a second thought. I think that's consistent with the Humean approach you describe. And, just maybe, it allows the (no matter how theoretical and nominal) chance for the magical wonders of the universe we seem to long for in our post-Enlightenment era.

    One issue that has long puzzled me in this context is actually *why* we want to establish reality; to put it plainly, why do are we so desperate to know things that, for all practical purposes, seem to have no effect on our existence? Perhaps it's some sort of anthropocentrism at work, I don't know.

    I also recall David Chalmers's (in)famous essay on the Matrix and the possibility we're in a simulation, where he basically suggests that, in the end, it makes little difference whether we consist of atoms or bits of information ("God put dinosaurs there!"), since, in this framework, the mere appearance of our reality (i.e. our impression that we consist of atoms and life is mostly as we think it to be) is tautological with its actually being like that.

    1. I don't know if you've bothered to translate my blog's subtitle, it's a serious statement, but I find it funny as hell and I can't explain why, it reads: "I think we're all suffering from the same metaphysical crisis". This relates to the Chalmers quote. But here's the deal: I think we want to figure out why reality is as it is (say, why the laws of physics are such and such, instead of otherwise), because that would ground our reality on something inhuman and it would relieve our shoulders from figuring out we have to decide how it is. I honestly believe it's something along these lines, we want to not be so responsible for how everything goes. It's somewhat akin to realizing Psychoanalysis or Marxism can account for a physicist's beliefs, but physics can't account for Marxism nor Psychoanalysis (yes, I am biased towards human sciences being way harder than natural sciences, this has personal, social, political, and historical reasons). More importantly to me, though: if existence itself is founded on possibility and chance, then social change is feasible. Let the revolution come! It is, indeed, a way of arguing from first principles against (pro-capitalist) notions of human nature/essence or something of the sort that is just used to oppress.

    2. Ironically enough, the "figuring out we have to decide how it is" part might actually be at least partially the case! - at least in some QM interpretations, and in some definitely abstract sense.
