?? ????? la ’adriyah

Skepticism, the doctrine that no certain knowledge is possible, for senses can deceive and reasoning may be false-a view, for example, adopted by Imam Ghazali (450-505/1053-1111 -website-) at one stage of his spiritual development. In-its extreme form, as with some of the Greek philosophers, skepticism means that one does not know anything, and not even that. See also Furun.

 ??? lams

The touch sensation: a power diffused in the skin and flesh of the animal body. When anything comes in contact with the body the nerves are stimulated and there occurs a change in the skin or flesh which leads to the sensation of touch. This is not a single sensation but one constituted of four pairs of sensations that we get from different sense-organs in the skin or flesh. These four pairs of contrary sensations are: heat and cold, dryness and wetness, roughness and smoothness, hardness and softness (see al-hawas al-zahirah). Through these sensations an animal is enabled to feel its way towards safe and profitable places and avoid those which are dangerous and unprofitable.

See also al-qadiyatan al-mutaqabilatan.
