I agree that we could question more what the perspectives that other living creatures have but the question then becomes how we go about doing that? Science and technology are getting pretty close to being able to "read" what goes on in the brains of humans including individual thoughts, etc. and it would be cool to also apply that (somewhat still future) tech to other animals and plants to better understand how they experience their subjective/individual lives and to what degrees they are sentient and thinking about life. Fun stuff to think about. :)
