Not Philosophy? :shock: You do know that modern philosophy crosses with science right? Anyways, I believe that it is because we have evolved this way, what we like today might have helped us survive a long time ago. For example, eating sweet stuff :P Sugar was probably scarce in the stone age lol, and our brain needs it. And now people like sugar for that reason, and as long as we don't die because of it, we will always like sugar. That's just an example, can't think of anything more right now.
