A Philosophical Explanation of Narrations about the Effect of Natural Environment on Man’s Cognitive Perceptions, According to Ibn Sina's Psychology

In narrative sources, there are some hadiths that somehow express the direct or indirect effects of human habitat and geographical location on the formation of his perceptions. Moreover, some narrations have directly mentioned the effect of foods on human function and perceptual ability. Based on Ibn Sina's rational explanation of the effect of nature on the soul, the reason for the effect of these factors on the perceptual ability and human soul is the elemental similarity of the human body and the elements of nature. According to Ibn Sina, the key role of the brain in human perceptions as well as the elemental similarity of all these things with each other are other causes of the effect of nature on the soul. The effect of the brain on perception and the effect of elements on the brain causes changes in perceptual ability in such a way that the difference in elements causes the difference in brain function and the difference in brain function causes strength and weakness or diversity and difference in perception and knowledge.
