On Teleology In my more Stoic moments, I'm inclined to believe in a form of pantheism, which for me is a suspicion based on suggestion, that the universe is imbued with a kind of intelligence in which we partake, now and then. But this isn't to say there is a design, which implies the existence of a designer of the universe Instead, it's to say the universe has a particular, more or less ascertainable, nature, constantly changing and growing. As to purpose, I find it impossible to assign anything like a purpose of the kind we might conceive to the universe. Unless it's possible to speak of growing or changing as a purpose.
C.S. Peirce had a most interesting view, which it may surprise some to learn was based on his work as a practicing scientist. As such he know that imprecision was characteristic of science and so wasn't inclined to believe in determinism, or in any mechanistic laws which govern the universe or any particular design inherent in it. He felt that chance played a continuing part in the universe, although he also thought that as the universe evolved over millions of years certain discoverable patterns or "habits" would arise. So, eons ago, the universe was far more spontaneous than it is now. He didn't believe in a designer or even a design as such as far as I can make out, but that the universe like an organism evolves over time.
