Senescence has evolved, some say, because genes that benefit the body during youth but have deleterious effects in age are not selected against until well after reproduction and the support of offspring. One wonders whether something similar has occurred in relation to the structures relating to our reasoning and our intuitions, our intuitions of transcedence for example. Our reason has evolved to solve problems in securing reproduction, and errors irrelevant to reproduction, because disconnected or so far subsequent in time, are simply not selected against or, at least, not until it is too late to matter.
