Often these assumptions are disguised as "apriori knowledge". Belief in a priori knowledge is touchingly naive. It is a philosophical superstition, just as souls are. | Often these assumptions are disguised as "apriori knowledge". Belief in a priori knowledge is touchingly naive.

Certainty is hardly an objective of science. Science is heuristic, not certain. | + | Science has a superior approach, modeling. You don't "believe" in models.

| + | === Calvinball === | ||
| + | Moral philosophy is [https://en.wikipedia.org/wiki/Calvin_and_Hobbes#Calvinball Calvinball]. Rules are made up as you go. Assumptions are added as needed to get the desired results. Every conclusion can be reversed by the addition of a sufficiently potent assumption. The fancy name for this is defeasible argument. The result is that moral philosophy is a post-hoc intellectual excuse for previously chosen positions. It can also serve as a quick introduction of where selected assumptions can lead, with the caveat that with minor tweaks the entirely opposite results can hold. | ||
=== Reifications === | === Reifications === | ||
The fallacy of treating an abstraction as if it were a real thing. Ideas such as "[[Inviolable Private Sphere of Rights]]" abound: indeed innumerable non-legal (moral) ideas of rights undergo reification. | The fallacy of treating an abstraction as if it were a real thing.

| + | === Naive Folk Models === | ||
| + | Many philosophical conundrums arise because of naive folk models which we know are not true. Ideas such as objects and identity are convenient labels that for some purposes suffice but are reifications. Boundaries cannot be clearly defined and time changes everything. I am not the same as I was a minute ago: it is merely a convenient folk model to treat me so. See [[A Is A]] for some examples. | ||

Engineers know that any time you scale up something, you can reach a point where it no longer works. Something that works between a pair of people might not work for a trio, for example. | Engineers know that any time you scale up something, you can reach a point where it no longer works.

| + | === Claiming that math is an example of objective truth === | ||
| + | I frequently see thing such as: | ||
| + | |||
| + | "2+2=4 is true whether or not you or I believe it. It's objectively true." | ||
| + | |||
| + | Wow, that is horseshit. 2+2=4 is one statement out of an infinitude which also includes 2+2=1. Neither statement is "true" in most senses of truth (please tell me which one you mean!) Both are abstract models that may or may not correspond to real world examples. For example, 2 water drops plus 2 water drops could equal one big water drop. And I highly recommend [https://www.gutenberg.org/files/2004/2004-h/2004-h.htm Pigs is Pigs] for a famous example of 1+1=thousands. In math, 2 infinities (aleph null) plus two infinities still equals one infinity. So mathematicians have counterexamples for your "objective truth". But there is also another facet of math you probably don't know. Math involves selection of statements based on their "beauty" (ie. desires of mathematicians.) Mathematicians usually prefer 2+2=4 because they find arithmetic beautiful: it is far more often superior for modelling than 2+2=1 usually is. In the development of calculus, philosophers complained greatly about infinitesimals and other concepts, but mathematicians found it beautiful anyway. | ||
| + | |||
| + | Nor are humans capable of objectivity or recognizing an objective truth. The best we have is intersubjective corroboration. | ||
| + | |||
| + | Another caveat: I don't know where people get the philosophical idea that math is objectively true. I haven't seen it attributed. | ||

That's how I view most philosophical ideas such as truth, justice, good, evil, etc. While you can study the relationships between such ideas endlessly, as you can the relationships between the Chinese categories, you do not have much hope of getting to the root explanations, as we have in biology, because the unifying basis is not obvious in these far descended ideas. Starting with such ideas is a pretty clear [[wikipedia:Skyhook_(concept)#Skyhooks_and_cranes|skyhook]]. These ideas need to be explained from much simpler, preferably positivist ideas rooted in evolution, anthropology, game theory, etc. | That's how I view most philosophical ideas such as truth, justice, good, evil, etc. While you can study the relationships between such ideas endlessly, as you can the relationships between the Chinese categories, you do not have much hope of getting to the root explanations, as we have in biology, because the unifying basis is not obvious in these far descended ideas.
