I Refute it Thus! The ‘faculty of reason’ is a perfectly intelligible expression, and the idea that humans alone possess it fully developed, and some animals only in very rudimentary forms, ought hardly need to be stated. — Wayfarer
I am familiar with this common argument and it has always left me somewhat cold. I don't have anything devastating against this view just some random thoughts. And yes, I'll be using reason.
Your wording seems very biased when you write things like "fully developed" and "very rudimentary forms" Surely that's a contingent viewpoint based on a series of assumptions?
This view is entirely predicated on
us identifying
ourselves as special - humans seem to have an innate ability to determine that we are favoured creatures of gods, and better/smarter than everything else on the planet. Is this not also one of our great blind spots - putting ourselves at the centre? Our reasoning is often indistinguishable from monomania. Perhaps this is why we have worked very hard to destroy the world and its wildlife. Reasoning often takes us to oblivion.
Is the line between us and animals so special because we have atom bombs and iPhones? Are our more complex adaptations and affectations a sign of superiority or really a kind of deficit?
It might even be argued that our particular brand of reasoning makes us inferior to animals who have and can find and do everything they need much more simply and elegantly than humans. They need no internet, no space programs, no Vogue magazine, schools or social media to thrive and live in harmony with nature. I'm not convinced that complexity equals superiority.
Our reasoning produces some useful and remarkable things (to us), but much reasoning is weak and bias ridden, and poorly inferred and dependent upon heuristics and simplifications. Humans have epic limitations on using reason which suggest we are simple and confused. (Yes, I know, this is your cue for something about higher actualization.)
Isn't one of the key arguments in Evan Thompson's
Mind in Life: Biology, Phenomenology, and the Sciences of Mind (2007) that consciousness is enactive? That is, it arises from dynamic interactions between the body and the world rather than being an intrinsic property or essentialist trait? This isn’t my area, but that sounds fascinating and I wonder what this says about animals.
