speaking of the unconscious
We all know in point of fact our minds have diffeent layers and Freud did the marvelous job indeed and he was the first one, maybe there others previous to him, to analyze human minds and their different layers so profoundly and scientifically.
In fact literature must be inspired by what is within, something lying ultold for a variety of reasons, like taboos and moral censorships in a particular social setting. Mostly all we do is we screen and filter all that wells up within the mind and things can not come spontaneously. You may love someone secretly and which is biologically justifiable and religiously or culturally tabooed. That desire lays seated there indefinitely.
A writer if he is bold enough must express something like that. A man may have , any morally right or so called men of dignity and disciplines may have something gin hiding, some urged pushed down.
Therefore writing must be frank and open.
There were many writers who emboldened themselves to express things that I said yet few could do fully and daringly.
