 The trine brain theory, the reptilian mind, paleo-mamalian mind, the neo-mamalian brain. According to the theory of evolution, we're actually high-functioning apes. May pag-animalistic ng nature natin. Sa reptilian mind. For example, nag-valable ka or nag-basketball ka. Puna rin nasagay kang ganun. Automatic ang response mo ganun ka din. Animalistic instinct, paleo-mamalian mind, dun naman responsible yung ating empathy. Kahit mga aso, mga pusa, they have that. Cannot fully call it love kasi instinctive siya. Dun papasok yung choice sa third one, sa neo-cortex. Abstract reasoning, logic, morals. Our actions are often influenced by our reptilian mind, paleo-mamalian mind. So kaya tayo nagiging li-active. Minsan. Right. And that's why we need the neo-cortex. That's what separates us. We learn to love with reason.
