Psychology.
Motion and light are not concomitant in the case of bodies of a lower order. A piece of stone, for instance, though illuminated and hence visible, is not endowed with self-initiated movement. As we rise, however, in the scale of being, we find higher bodies, or organisms in which motion and light are associated together. The abstract illumination finds its best dwelling place in man. But the question arises whether the individual abstract illumination which we call the human soul, did or did not exist before its physical accompaniment. The founder of Ishrāqī Philosophy follows Avicenna in connection with this question, and uses the same arguments to show, that the individual abstract illuminations cannot be held to have pre-existed, as so many units of light. The material categories of one and many cannot be applied to the abstract illumination which, in its essential nature, is neither one nor many; though it appears as many owing to the various degrees of illuminational receptivity in its material accompaniments. The relation between the abstract illumination, or soul and body, is not that of cause and effect; the bond of union between them is love. The body which longs for illumination, receives it through the soul; since its nature does not permit a direct communication between the source of light and itself. But the soul cannot transmit the directly received light to the dark solid body which, considering its attributes, stands on the opposite pole of being. In order to be related to each other, they require a medium between them, something standing midway between light and darkness. This medium is the animal soul—a hot, fine, transparent vapour which has its principal seat in the left cavity of the heart, but also circulates in all parts of the body. It is because of the partial identity of the animal soul with light that, in dark nights, land-animals run towards the burning fire; while sea-animals leave their aquatic abodes in order to enjoy the beautiful sight of the moon. The ideal of man, therefore, is to rise higher and higher in the scale of being, and to receive more and more illumination which gradually brings complete freedom from the world of forms. But how is this ideal to be realised? By knowledge and action. It is the transformation of both understanding and will, the union of action and contemplation, that actualizes the highest ideal of man. Change your attitude towards the Universe, and adopt the line of conduct necessitated by the change. Let us briefly consider these means of realisation:—
A. Knowledge. When the Abstract illumination associates itself with a higher organism, it works out its development by the operation of certain faculties—the powers of light, and the powers of darkness. The former are the five external senses, and the five internal senses—sensorium, conception, imagination, understanding, and memory; the latter are the powers of growth, digestion, etc. But such a division of faculties is only convenient. "One faculty can be the source of all operations."[142:1] There is only one power in the middle of the brain, though it receives different names from different standpoints. The mind is a unity which, for the sake of convenience, is regarded as multiplicity. The power residing in the middle of the brain must be distinguished from the abstract illumination which constitutes the real essence of man. The Philosopher of illumination appears to draw a distinction between the active mind and the essentially inactive soul; yet he teaches that in some mysterious way, all the various faculties are connected with the soul.
The most original point in his psychology of intellection, however, is his theory of vision. [142:2] The ray of light which is supposed to come out of the eye must be either substance or quality. If quality, it cannot be transmitted from one substance (eye) to another substance (visible body). If, on the other hand, it is a substance, it moves either consciously, or impelled by its inherent nature. Conscious movement would make it an animal perceiving other things. The perceiver in this case would be the ray, not man. If the movement of the ray is an attribute of its nature, there is no reason why its movement should be peculiar to one direction, and not to all. The ray of light, therefore, cannot be regarded as coming out of the eye. The followers of Aristotle hold that in the process of vision images of objects are printed on the eye. This view is also erroneous; since images of big things cannot be printed on a small space. The truth is that when a thing comes before the eye, an illumination takes place, and the mind sees the object through that illumination. When there is no veil between the object and the normal sight, and the mind is ready to perceive, the act of vision must take place; since this is the law of things. "All vision is illumination; and we see things in God". Berkley explained the relativity of our sight-perceptions with a view to show that the ultimate ground of all ideas is God. The Ishrāqī Philosopher has the same object in view, though his theory of vision is not so much an explanation of the sight-process as a new way of looking at the fact of vision.
Besides sense and reason, however, there is another source of knowledge called "Dhauq"—the inner perception which reveals non-temporal and non-spatial planes of being. The study of philosophy, or the habit of reflecting on pure concepts, combined with the practice of virtue, leads to the upbringing of this mysterious sense, which corroborates and corrects the conclusions of intellect.
B. Action. Man as an active being has the following motive powers:
(a). Reason or the Angelic soul—the source of intelligence, discrimination, and love of knowledge.
(b). The beast-soul which is the source of anger, courage, dominance, and ambition.
(c). The animal soul which is the source of lust, hunger, and sexual passion.
The first leads to wisdom; the second and third, if controlled by reason, lead respectively to bravery and chastity. The harmonious use of all results in the virtue of justice. The possibility of spiritual progress by virtue, shows that this world is the best possible world. Things as existent are neither good nor bad. It is misuse or limited standpoint that makes them so. Still the fact of evil cannot be denied. Evil does exist; but it is far less in amount than good. It is peculiar only to a part of the world of darkness; while there are other parts of the Universe which are quite free from the taint of evil. The sceptic who attributes the existence of evil to the creative agency of God, presupposes resemblance between human and divine action, and does not see that nothing existent is free in his sense of the word. Divine activity cannot be regarded as the creator of evil in the same sense as we regard some forms of human activity as the cause of evil.[145:1]
