I've been using the term "definition" loosely in my statements. No, I agree, when people respond to new experiences they don't worry about putting together a theory and testing it against a set of axioms they've chosen according to some set of rules they've been taught. But neither do they just respond in some random manner. There's a built-in bias for people to act in a particular manner given a particular situation. The universe is infinite; we aren't. There are an innumerable amount of ways to, say, categorize the variety of objects on my lawn, but people are immediately able to pick out the rabbits there as important objects, rather than discussing the rabbit ears on my lawn, or the rabbit feet, or the individual hairs of rabbit fur. Those are all valid objects out there, but we, by default, generally consider an animal as a unit, separate from the world around it. If we didn't, it would be much harder for us to deal with the world around us! Anyway, I'm just saying we have some amount of instinct in us.
