This originates from a sort of "subjectivism" and "mental escape from realities" and "resorting to fancy" which is proved today in psychoanalysis. The sense does not appertain to this case. Rather, all cases in which man's desires are not satiated outwardly, and retreat to unconscious inner sense as repressed, man seeks for visionary and fanciful substitutes in order to fill the vacuum created in that respect.

Sometimes, he seeks them in the dreamy world (a part of dreams are the effect of this cause). And sometimes he seeks them in the world of "poetic imaginations" and "dreams in wakefulness", and for this reason, the able poets in whose poems there are affection, enthusiasm, influence and mirth, are those who in addition to poetic talent, have faced disappointments, loss and failures, fiery kindness' and unsuccessful loves, and have sought their lost and beloved one in the world of imaginations among the poetic masterstrokes and literary niceties, and thereby their imagination power has extremely developed.

In brief, "mental escape towards fancy" is the source of a lot of mental events, including suspicion, pessimism and mistrust. 2- Sometimes, the source of suspicion is impurity and taint of man, as too much optimism originates from the purity and serenity of a man. That is to say a man assumes the others good or bad based on the principle of "self comparison". This is particularly apparent in low knowledge and simple persons.

3- Excusing or reducing one's own punishment in the court of conscience is also one of the other causes of suspicion, because in this way he tries to create some partners for his offences, and suspects on the others for justifying his own ill deeds, and showing them less effective and more usual, and saying that I am not the only one being involved in this state.

4- Suspicion may originate from pride and selfishness, because such people intend to show themselves superior to the others in any way, and so try to create some weak points for the others in the environment of their mind, and devaluate them through different probabilities, and elevate their own value. 5- Educational environment and suggestions of parents and teacher are also important causes of pessimism and suspicion.
