Final answer:
Schopenhauer's advice is to rely on our conscience and use reason to deal with our animal instincts.
Step-by-step explanation:
Schopenhauer's advice about how to deal with our animal instincts is most consistent with the idea that our conscience becomes the supreme judge and monitor.
While we may be influenced by the praise or blame of others, our habitual convictions, controlled by reason, provide us with a safe rule.
Schopenhauer also recognizes that the first foundation of the moral sense lies in the social instincts, including sympathy.
Therefore, to deal with our animal instincts, we should rely on our conscience and use reason to guide our actions.
