Many scientists believe teleology involves human action. The role of necessity and contingency are vital. Phrases like, “In order to…” and “It just so happens that…” are contingencies. Before proceeding I’ll make a quick distinction between metaphysics and epistemology. Metaphysics includes being and becoming. Each have respective higher and lower forms. Being’s higher form is beauty, justice, etc. The lower form is triangularity, humanity, etc. Becoming’s higher and lower are sensible things and images, respectively. Epistemology includes knowledge and opinion. Knowledge pertains to understanding and reasoning. Opinion refers to perception and imagination.
Teleology refers to final causation. Aristotle’s science included four different causes: material, formal, efficient, and final. For instance, consider a marble statue of a man. The material cause is the stuff, the marble. The formal cause is the whatness/sort, the statue. The efficient cause is that which brings it into being, the sculptor. The final cause is the end purpose, David.
Can teleology simply be an implication? Information has origin in mind but we know minds act in accordance to purpose, thus teleology is an implication and not a direct conclusion. Natural causation cannot bring about directionality or intentionality. Many philosophers of science, i.e. Alex Rosenberg, want to get us as close to nomic necessity as possible. Simply put, many philosophers, including Rosenberg, believe efficient causation is not satisfying.
