This is a throwback to the Aristotelian conception of nature, banished from the scene at the birth of modern science. But I have been persuaded that the idea of teleological laws is coherent, and quite different from the idea of explanation of the intentions of a purposive being who produces the means to his ends by choice. In spite of the exclusion of teleology from contemporary science, it certainly shouldn't be ruled out a priori. Formally, the possibility of principles of change over time tending toward certain types of outcome is coherent, in a world in which the nonteleological laws are not fully deterministic.
