Furthermore, internal contents and conditions influenced by external factors can change the identity of the external factors, too. For instance, let's say we encounter a dead body. What we feel through our senses is the view of a dead person. If the dead body belongs to a close friend, it would cause sorrow, and if it belongs to an enemy it would delight us. Two different reactions to a single phenomenon; hence, how internal factors can influence our perception of external facts.

In fact, man's natural senses are justified through internal factors. In other words, phenomena that enter us through our senses are interpreted and accounted for by man's own wishes and knowledge. 2- Artificial Devices and Tools: Man has made tools and devices to help him explore nature and the universe. The invention of the telescope, the microscope, and many other devices has helped man discover phenomena he could never explore using his own senses.

No matter how powerful these devices may become, they cannot eliminate the role of the senses and internal conditions; they cannot change the mind into a mirror which passes things into humans exactly as they are. The reasons for this are: a) These tools and devices are man-made, so they are dependent upon man's selection or elimination. b) What tools and devices reflect to man is limited to certain circumstances.

For example, they reflect insect fur, the human body, mercury, leather and cement each in a different way. Any modification in the magnifying glass can influence the appearance of the observed phenomena. c) Even if the artificial tools and devices reflect facts as they are, the internal passages they must go through will affect them, for they are being received by human senses and mind.

3- Man's innate talents and powers, such as intelligence, wisdom, imagination and thought can also serve as tools of discovery. The Importance of Adjusting and Refining the Senses Intellectuals studying identification and recognition have neglected the issue of adjusting and refining knowledge in both domains of the mind and in the real world. From the mental aspect, the function of the senses must be corrected, for any fault in the senses may deform the reality.

Thus, man's internal management should take charge of adjusting the senses. Apart from adjusting and refining the senses and tools that make possible the contact between man and facts, the mind also needs adjustment and refinement.
