Philosophy in the Flesh, a book about the embodied mind and how language comes from our physical experience of the world. http://www.amazon.com/Philosophy-Flesh-Embodied-Challenge-Western/dp/0465056741
This is my favorite linguistics and etymology website: http://linguisticmystic.com/
I discovered that site through looking into the etymology of peacock mantis shrimps, one of my favorite animals. His entry on the suffix -mancy is clever: http://linguisticmystic.com/2007/05/21/a-truly-divine-suffix-mancy/
i also spent several years studying "knowledge representation" which is a field within AI and cognitive science, about computers modeling how we process language. http://en.wikipedia.org/wiki/Knowledge_representation_and_reasoning
This book about Sanskrit mantras was recommended to me for my studies of "conscious language", where the graphemes and phonemes of the root syllables of a language correspond intentionally with the physics of the universe, or something like that. I can't for the life of me find an online resource for this idea, but I continually have in person conversations with esoteric scholars of various kinds about it. I suppose that's part of what is meant by a conscious language, it's simply alive and present. Quechua also feels very much like this for me when I hear it spoken, only it feels particularly interdimensionally active. http://www.amazon.com/Mantra-Yoga-Primal-Sound-Mantras/dp/0910261946
I don't even know why I get so extremely nerdy about this. I suppose I can be an incredibly literal person and I'm always curious why people choose the words they do. Also I feel like I grew up outside of language, since my experience as a superpsychic sensitive person was so out of synch with how people around me in the midwest were talking and interacting. When I went to college in Boston and was exposed to intellectual thought for the first time, I was around a bunch of math and philosophy nerds, that kinda got me started. I'd love to have another conversation with a linguist I took a class from there, who spoke over 20 different languages and he was only 26. I wrote a paper that classified language games...
Perhaps the root of it for me is that I still feel like few people speak my language, and I'm still searching for how to convey my experience. Diana Reed Slattery I'm looking forward to talking with you. People reading this, her website is incredible: http://psychedelicsandlanguage.com/
My current dorking out on this topic is largely centered around biochemistry and biophysics - how our cells, bacteria, and plants etc all communicate and interact with each other. Victor Hanson-Smith I really wanna pick your brain more about DNA mechanics.
Also I like nerding out with sound scientists who study sound waves and the nature of electricity. I'm going to do a series of interviews soon with different sound scientists coming from different perspectives and takes on it... My intention is to help people experience sound directly instead of through language. There's something profoundly spiritual and connecting about suspending the endlessly compartmentalizing language mind and just listening.
