Except you don't. You've rambled on about nihilism and regurgitated some stuff from Einstein and Aristotle, but you've never answered the question.
You've still not demonstrated why teleology is apparently essential to self developing beings for cultivating values. I know plenty of people who cultivate a wide range of values and none of them really have to resort to teleology to develop those values, so what gives?
If it's so essential to cultivating values, how come so many people manage to do so without it?
Let me say it like this. Hume’s Law shows that we are perpetually stuck in the problem of induction, with no certainty about our self or the future. We do, however, act correctly from time to time. The gazelle zigs while the tiger zags, and is afforded another opportunity to reproduce, Ceteris Paribus.
Animals with little cognitive function don’t rely on thinking, but instinct, in order to maintain an equilibrium with their environment. I’m not suggesting that this is their intent. This would be the domain of King’s theory of evolution. Darwinian evolution throws competition into the mix, and with scarce resources we get another form of evolution.
Intelligent beings overcome the stability or instability of environmental factors by being able to guess correctly about some future state, hence culture. Conjecture is just a fancy word for guess, and the guess is about some design that may or may not obtain. Sometimes the guess is beneficial and sometimes it is not. The history of science is the history of either failed or outgrown theories. It’s a process. Scientists make conjecture for the purpose of learning new information.
The conjecture about future states is teleological. I don’t think this is resorting to teleology, but showing the reality of teleology in any development of values such as scientific conjecture. If you think people manage to do without it, perhaps you should rethink your position. If you don’t believe it, then for what purpose do you keep inquiring? Are you thinking or acting on instinct? If you are thinking, what is your end goal? If you don’t have an end goal, then you are not thinking, but acting on instinct. Either one is ok, and sometimes you can tell the difference about other peoples states.
