‘Abd al-Latif goes on by explaining that in human knowledge there are three sorts of cognitions: those acquired by senses, frequently insufficient, those first necessary cognitions that originate with man, and those acquired by investigation and consideration. ‘Abd al-Latif asks himself what type of knowledge is most appropriate for man. Animals, too, in fact, have a body, senses, and the ability to discern how and with what to safeguard their health. They do not, however, possess the desire, provoked by wonder, to know the causes of what can be seen in the heavens and on earth.
