“A fox knows many things, but a hedgehog knows one big thing.”

For there exists a great chasm between those, on one side, who relate everything to a single central vision, one system, less or more coherent or articulate, in terms of which they understand, think and feel — a single, universal, organising principle in terms of which alone all that they are and say has significance — and, on the other side, those who pursue many ends, often unrelated and even contradictory, connected, if at all, only in some de facto way, for some psychological or physiological cause, related to no moral or aesthetic principle.

These last lead lives, perform acts and entertain ideas that are centrifugal rather than centripetal; their thought is scattered or diffused, moving on many levels, seizing upon the essence of a vast variety of experiences and objects for what they are in themselves, without, consciously or unconsciously, seeking to fit them into, or exclude them from, any one unchanging, all-embracing, sometimes self-contradictory and incomplete, at times fanatical, unitary inner vision. The first kind of intellectual and artistic personality belongs to the hedgehogs, the second to the foxes.

Its been over a decade since I read this essay, so I cannot remember, but wikipedia assures me that Isaiah Berlin said Tolstoy was, by nature, a fox, but by conviction a hedgehog.

Maybe I need to reread it.

I wonder if he offers any examples of poor souls who were, by nature, a hedgehog, but by circumstance, the foxiest of foxes.

There is a fine and blurry line between cognitive impairments and a sense of purpose in life.

Behind one species of hedgehog — let’s call it the involuntary hedgehog — there is a small set of highly developed abilities, organized as a methodology. Part of the methodology is seeing the world that reveals applications for the methodology.

This hedgehog can do all sorts of things with this methodology — as long as he is allowed his methodology. Take the methodology away, the hedgehog’s quills are plucked and he looks like a shaved runt fox. Tragically, one of the methods in the methodology is not providing itself the conditions needed to apply the methodology. If the hedgehog’s quills are plucked, the hedgehog cannot defend itself long enough to restore or regrow them.

I can use design to solve all kinds of problems — but only if I have conditions to design.

If I am prevented from designing, I am well and truly fucked.
