In the heart of Imam Khomeiniway of thinking, ethics has a [special] place, and in fact, all areas of knowledge revolve around this pivot.
According to his view, by citing a hadīth (Prophetic tradition) from the Messenger of God, all kinds of knowledge can be placed in three general categories.
It is because the human being possesses three existential presences and three types of world: one, external and sensory; another, the allegorical world; the third, the intellectual one.
Social science, juristic precepts and transactions are examples of the first category while rational sciences are instances of the third type.
Yet, what is related and complementary to the second type is called ethics. If man wants to go beyond logic and the law of instincts, then he needs ethics in its broad sense.
Ethics in this context cannot be confined to merely a number of ethical rules; instead, it is in fact a knowledge which searches for the deepest recesses of man’s existence, and which cures him.
