 Of course, there is no reason why the Lokāyata philosophers should say that the body is changeless. It might precisely be the changes that appear in the body, for example in the brain, which are responsible for cognition. Dharmakīrti argues that if cognition required the support of the body, there is no reason why it should not arise everywhere where there exists a body or matter [PV 37–38]. The obvious objection to this argument is that not any form of matter supports cognition. It has to be a particular kind of matter, ordered in a particular way, as is the case in human beings and many animals.
