“…either we behave like intelligent, rational animals, respecting Nature and accelerating as much as possible the process of humanization we are only just beginning, or the quality of human life will deteriorate. Some of us are starting to have doubts about the rationality of human groups. But if we do not act rationally, we will suffer the same fate as some cultures and some stupid species of animals, of whose suffering and path to extinction all that remains are fossils. Species that do not change biologically, ecologically or socially when their habitat changes are bound to perish after a period of indescribable suffering.” EvolutionRationalityRational ThinkingHuman EvolutionHuman Evolution And Tolerance Book:Teoría Y Práctica De Salud Pública Source: Teoría Y Práctica De Salud Pública
