There is plenty in philosophical literature which is not just analysis or elaboration of the work of science, and which is not modeled on science. What I stress is that philosophical discourse should at least strive for honesty, clarity and coherence, and that philosophers should not make obscurity a virtue, and should not offer vagueness and equivocation as profundity. I don’t have much patience for the pretentious type of speculative metaphysics which often parades as profound philosophy.
