We are justified in saying that they have been diverted from these sexual aims, even though there is some difficulty in giving a representation of such a diversion of aim which will conform to the requirements of metapsychology. Moreover, those instincts which are inhibited in their aims always preserve some few of their original sexual aims; even an affectionate devotee, even a friend or an admirer, desires the physical proximity and the sight of the person who is now loved only in the 'Pauline' sense. If we choose, we may recognise in this diversion of aim a beginning of the _sublimation_ of the sexual instincts, or on the other hand we may fix the limits of sublimation at some more distant point. Those sexual instincts which are inhibited in their aims have a great functional advantage over those which are uninhibited. Since they are not capable of really complete satisfaction, they are especially adapted to create permanent ties; while those instincts which are directly sexual incur a loss of energy each time they are satisfied, and must wait to be renewed by a fresh accumulation of sexual libido, so that meanwhile the object may have been changed. The inhibited instincts are capable of any degree of admixture with the uninhibited; they can be transformed back into them, just as they arose out of them. It is well known how easily erotic wishes develop out of emotional relations of a friendly character, based upon appreciation and admiration, (compare Molière's 'Embrassez-moi pour l'amour du grec'), between a master and a pupil, between a performer and a delighted listener, and especially in the case of women. In fact the growth of emotional ties of this kind, with their purposeless beginnings, provides a much frequented pathway to sexual object-choice. Pfister, in his _Frömmigkeit des Grafen von Zinzendorf_,[72] has given an extremely clear and certainly not an isolated example of how easily even an intense religious tie can revert to ardent sexual excitement. On the other hand it is also very usual for directly sexual tendencies, short-lived in themselves, to be transformed into a lasting and purely tender tie; and the consolidation of a passionate love marriage rests to a large extent upon this process.
