“The stars are the apexes of what wonderful triangles! What distant and different beings in the various mansions of the universe are contemplating the same one at the same moment!” (H.D. Thoureau)
Thoreau probably did not have in mind stellar parallax in relation towards distance computation, and his imagined use of triangulation is more a heartfelt outreach to find resonance with another, be it of this world or otherwise. Still, there may be something in Thoreau’s words that transcends their initial appearance and speaks more directly to Mr Watson’s musings.
Thoreau continues from the above: “Nature and human life are as various as our several constitutions. Who shall say what prospect life offers to another? Could a greater miracle take place than for us to look through each other’s eyes for an instant? We should live in all the ages of the world in an hour; ay, in all the worlds of the ages. History, Poetry, Mythology! — I know of no reading of another’s experience so startling and informing as this would be.”
Paraphrasing and taking enormous license with the inimitable Thoreau and one contemporary other, perhaps the inspiring lines above may be reduced to the more familiar and definitely modern – “a latticework of mental models.”
Mr Watson rightly postulated “internal, mental” parallaxes predicated upon by any number of possible variables. But one fears that trying to elucidate error terms in any single mental construct may necessitate recourse to never-ending phenomenological reduction and render any resulting “cognition” and perceived derivative error to be indeed, in doubt.
The unkindest and yet most impersonal a priori parallax may come from the observer himself, delivered through the remorselessly agnostic Observer Effect. In the context of the markets, presupposing that the state of a market system exists independently of its observer/participant will surely be unwise and inevitably, loss-making.
But here is a naive yet hopeful thought — perhaps singular errors from any one mental construct matters less from the perspective of the whole. If every man holds in his mind (and inherently all men do, to a greater or lesser degree), a “latticework of mental models”, then in a mind where the structural tensions and forces remain basically stable, it follows that individual mental disjoints/errors have mitigated and largely damped themselves out.
Perhaps a healthy dose of History, Poetry, Mythology! shall prove to be rather profitable…
