Sociology has a foundation in universal law, to be sure.
Max Weber, Auguste Comte, and other early sociologists had a lot of brilliant insights which, though far-fetched, are gaining more credence today. A lot of the theories of psychology and sociology have something which seems rather unscientific in them, but which is intuitively and also clinically verifiable. Now, in science, we are coming to the end of the dominance of purely materialistic dogma. Even in astronomy, they just demonstrated antigravity on the cosmic level, as one of the fundamental forces. It shakes up the whole worldview of a dead, mechanistic universe.
