Stirring the hornets nest

In his magnum opus, World as will and idea, on the topic of heredity, Arthur Schopenhauer claims a person’s character is inherited from the father and intellect from the mother.

He further argues, that for a while women had not the opportunity for intellectual pursuits thus depriving the world of monuments/ literary works by women. Were it for this restriction, he argues his claim about intellectual inheritance would be much more pronounced. He proposes as proof that you look for examples around you.

Is there any truth to his claims? I will do an audit of my family and report in future.
