"Freud's view is that all love is sexual in its origin or its basis. Even those loves which do not appear to be sexual or erotic have a sexual root or core. They are all sublimations of the sexual instinct"

The quote is revealing Freud's theory that all kinds of love have a foundation in sexuality, even if it is not directly viewed as sexual. This sexuality is believed to be the essential driving force which is then redirected and fulfilled through various kinds of love. According to Freud, this instinctual energy can be sublimated or redirected into non-sexual expressions of love. Mortimer Adler mentions Freud's consider as the basis for understanding the origins of all types of love.
