Maimonides on the Influence of Negative Emotions on the Imagination
”We have thus described three kinds of perfection: mental perfection acquired by training, perfection of the natural constitution of the imaginative faculty, and moral perfection produced by the suppression of every thought of bodily pleasures, and of every kind of foolish or evil ambition.
These qualities are, as is well known, possessed by the wise men in different degrees, and the degrees of prophetic faculty vary in accordance with this difference.
Faculties of the body are, as you know, at one time weak, wearied, and corrupted, at others in a healthy state. Imagination is certainly one of the faculties of the body. You find, therefore, that prophets are deprived of the faculty of prophesying when they mourn, are angry, or are similarly affected.
Our Sages say, Inspiration does not come upon a prophet when he is sad or languid. This is the reason why Jacob did not receive any revelation during the period of his mourning, when his imagination was engaged with the loss of Joseph. The same was the case with Moses, when he was in a state of depression through the multitude of his troubles, which lasted from the murmurings of the Israelites in consequence of the evil report of the spies, till the death of the warriors of that generation. He received no message of God, as he used to do, even though he did not receive prophetic inspiration through the medium of the imaginative faculty, but directly through the intellect.
There were also persons who prophesied for a certain time and then left off altogether, something occurring that caused them to discontinue prophesying. The same circumstance, prevalence of sadness and dullness, was undoubtedly the direct cause of the interruption of prophecy during the exile: for can there be any greater misfortune for man than this: to be a slave bought for money in the service of ignorant and voluptuous masters, and powerless against them as they unite in themselves the absence of true knowledge and the force of all animal desires? Such an evil state has been prophesied to us in the words, “They shall run to and fro to seek the word of God, but shall not find it” (Amos viii. 12).
This is a real fact, and the cause is evident; the pre-requisites [of prophecy] have been lost.
