People have expressed interest in deep topics, so this list focuses on philosophical questions.

If freedom is simply being able to do what you want, are animals freer than humans?

Animals are more free than humans to choose their actions based on whatever they want, whereas most humans are greatly limited by laws, expectations, and other cultural factors. However, animals are more ruled by instincts than humans, which curtails what animals want and choose; humans can (but often don't) decide to overrule their instincts.
