Carl Sagan je sugerirao da se moramo fokusirati na reptilski mozak, jer od tamo dolaze ovi primitivni nagoni, za agresijom i teritorijalnosti, pogotovo u doba kada vodimo brojne ratne sukobe.
Carl Sagan suggested that we need to actually focus on the reptilian brain because that's where these primitive urges of aggression and territorialism come from, especially in an age where we're involved with a lot of war and conflict.
