According to Peripatetic thought, Specially Avicenna, material particulars are known through two minor ways: sometimes through perceptual organs and the other whiteout getting help from perceptual organs. The perception that occurs through perceptual organs is called sense perception. And the other without getting help from perceptual organs and is occurred by object causes is called perception of particulars in universal or general mode. Some of the latter perception's characteristics are: mediation of perception of general causes in knowing the unique general example and its effect, obtaining knowledge without object known and consequently the knower's ignorance of sensual object known. Avicenna used this perception in three places: first the knowledge of soul to her perceptional and moving tools. Second a prior knowledge to particulars (materials) which is obtained intellectually by its causes and third God's a prior knowledge to changing particulars (materials). Peripatetic thought in man a prior knowledge to particulars is functional however there are some problems in the two others.
