What does Victor say about his temper and vehement passion when he was young?

Althoughsays that his parents provided
nothing but a lovingfor him and that he and Elizabeth enjoyed only "harmony" in their
relationship, he admits that he personally has a flaw in his temperament:

My temper was sometimes violent, and my passions vehement; but by
some law in my temperature they were turned not towards childish pursuits but to an eager desire
to learn, and not to learn all things indiscriminately. (Chapter 2)

Victor seeks a depth of knowledge even from childhood. This passion
to understand the laws of nature which govern the world around him are sometimes consuming,
leading him to become agitated in his quests. He longs to understand the "physical
secrets" of the world, and it is this part of his character which drives him to contemplate
the possibility of creating a human(like) figure. It likely also drives his reaction tohe
constructs, leading him to respond in this "violent" temper to the creature's various
requests.

With his family, Victor is patient. In scientific quests and
learning, he is so passionate that his personality leans toward violence in spirited quests for
understanding.
