use the criteria of instinct and intelligence to divide animals from humans

Your dog loves to curl up on the couch,but so do you,so you shoo him off and settle in for a cozy evening.After all, you're the human around here.You're an intelligent being,not a simple creature of instinct.You can plan and dream, and oh-Did your dog just outsmart you and feel happy about it?Or was he just following his instincts?Is there even a difference?What is he thinking?Well, it depends on what we mean by thinking and the criteria we use to evaluate it.Aristotle and Descartes both use the criteria of instinct and intelligence to divide animals from humans.
