The debate concerning the origin of our minds stems back to the diverging opinions of Darwin (1871) and Wallace (1870). When Charles Darwin first discussed the evolution of our seemingly unique cognitive faculties, he proposed that there is “no fundamental difference between man and the higher mammals in their mental faculties.” (Darwin, 1871, pg. 66). Conversely, Wallace was suspicious of whether natural selection alone could have shaped the human mind, writing: “[…] that the same law which appears to have sufficed for the development of animals, has been alone the cause of man’s superior mental nature, […] will, I have no doubt, be overruled and explained away. But I venture to think they will nevertheless maintain their ground, and that they can only be met by the discovery of new facts or new laws, of a nature very different from any yet known to us.” In the intervening years, the debate surrounding the degree of continuity between animal and human minds still rages on in contemporary discussions (Bolhuis & Wynne, 2009; Penn, Holyoak & Povinelli, 2009).
Having handed in my disseration and, with the notable exception of graduation, all but completed my course, I’m now free to spend much more time working on this blog. From now on I’m hoping to post at least an article a day — varying from research-related posts to just my reading for the day. Probably the most pertinent thing to write about is what I have been working on over these past few months, but being a precocious topic-hopper I’m going to provide a video of Nassim Nicholas Taleb, an economist who appears to hold a lot of sensible views about the economy.
N.B. The video I was watching doesn’t appear to be compatible with wordpress. So, here is the link to that video, and the video below is a far shorter segment from Newsnight. It’s dumbed down to the extreme, but you get the gist of Mr Taleb’s stance. Enjoy.
When exploring the etiology of schizophrenia, a feat that has mostly eluded understanding for over 100 years, a common denominator emerges in that associated deficiencies are rooted in cognitively demanding tasks. One suggestion is that, where schizophrenic individuals are involved, disorganised thoughts, abnormal speech, auditory hallucinations and paranoid delusions are symptomatic consequences of our haphazardly evolved brains. It might not seem revelatory, nor is it a particularly new thought on the matter, yet this disorder clearly has ties with human-specific, recently evolved behaviours, such as language and social relationships. And it is here in which our problem emerges: we don’t even know how language or social relationships evolved. In fact, the evolution of the human brain is still very much an enigma, despite the whole host of literature having you believe otherwise. As Darwin put it: “Ignorance more frequently begets confidence than does knowledge[…]”.
