In part, Arthur Schopenhauer was depressive, as was his father, whom he believed to have self-murdered. As despressive, his anima, projected as blind force-mothering of world as will, became his philosophical opinion based on Kantian phenomenalism, Schopenhauer reductively rejecting Kantian God Noumenalism for simpler if illogical atheism.
His mother took the opposite polarity of the feminine, being vivacious and lively; she and Arthur agreed they disliked each other. As for further expression of masculinity, Arthur would bed lower-class females, as a kind of forceful, masculine overcoming of his own non-vivacious anima as projected upon the hapless, temporarily vivacious female. He wrote "Marrying means to grasp blindfolded into a sack hoping to find an eel amongst an assembly of snakes," very perceptive of him. On the other hand, he was successfully sued by one Caroline Marquet, who Schopenhauer, in court, testified that he believed had deliberately talked loudly outside his door (he pushed her to the #MeToo ground). After she died, he, no longer having to pay her damages awarded by the court, wrote on a copy of her death certificate, "Obit anus, abit onus," "The old woman dies, the burden is lifted." When Arthur's mother reviewed his "On the Fourfold Root of the Principle of Sufficient Reason" as "incomprehensible," he accurately informed her that his work would be read long after the rubbish she wrote was forgotten. He kept a series of poodles, replacing one after another when necessary, always naming them eitber Atman or Butz.
Concluding unscientific postscript: His spirit animal may have been Eeyore.
p.s. To answer your question, Kant stated he learned moral law literally at the knee of his beloved mother; of that, the Categorical "golden rule" Imperative arose--good will to mankind. Schopenhauer did not absorb his mother's vivacity, but followed his father's pessimism; per that, lower-class females could be bonked, but kept at lust's length; living alone for the last 27 years of his earthly life does not indicate as much good will as the bachelor Kant showed during his later days.
