Abstract

Only those who seek science for the sake of science are interested in issues such as making comparisons between Mulla Sadra's theories and those of contemporary scientists. That is, those contemporary scientists, who are inclined to philosophy.According to modem sciences, the changes in chemical substances are resulted from reactions in molecular level, and molecules, consist of atoms, which in turn, contain many constituents. We will not discuss this issue here. If we consider the constituents of atom and quanta of light, certain cases can be seen which refer to Mulla Sadra's trans - substantial motion.Light, when in motion, has neither a corpuscular structure nor a wavy one. We do not consider such a thing as a material one, (hough it has material effects, that is, imparts influences 'on our measuring devices.
