00:00Do you need anything other than the purely physical world?
00:04Yes, we do need something beyond the brain to be declared conscious,
00:11but that's not a big need because that's something that pre-exists this question.
00:20If I am asking, what is it that is needed for an entity to be called sentient or conscious?
00:30Then by virtue of existence of the questioner, the question has already been answered.
00:38The one asking the question is the one that is needed for the entity to be called conscious.
