The greatest intellectual divide is not between those who believe one thing and those who believe another, but between those who have an emotional need to believe something fervently and those who can say, “I don´t know.”

Next, consider evolutionary psychologists. They believe that our behavior is determined by adaptations selected for tens of thousands of years ago. Yes, no, and maybe. A lot of our behavior is clearly biological in nature, which is not quite the same as evolutionary (note the discovery by adolescent boys that girls are not as yucky as they had previously supposed). Yet a lot of behavior isn´t explainable in evolutionary terms.
Examples abound: what is the reprocuctive value of suicide, masochism, sadism, schizophrenia, and so on.? Should these not be filtered from the gene pool? A Neanderthal who thought that the CIA put transmitters in his teeth and tried to shake hands with Kodiak bears might limit his reproductive opportunities.
Again, the problem is Domain Bloat, insisting thet one´s theory explain what it can explain but also what it can´t.
