 On this interpretation, al-Ghazālī’s skeptical argument merely denies that the evidence of repeated observation shows that natural bodies are the sole causes of change. So, that argument is compatible with the claim that the evidence of repeated observation indicates that natural bodies are among the causes of change. Averroes, however, suggests that al-Ghazālī denies the latter claim. So, his argument from natural science does not succeed against al-Ghazālī’s skeptical argument. On the other hand, to allow that natural bodies are among the causes of change may not be sufficient to avoid a problem raised by Averroes’ argument from natural science. Averroes’ argument involves the idea that repeated observation of bodies gives us insight into their natures. By “nature” is meant an intrinsic principle of motion and coming to rest. So, the argument demands more than the concession that natural bodies make some causal contribution to change. It demands that the causality of natural bodies is rooted in and explained by their natures.
