Disability taken as a concept is a perfect Boolean figure. If X = the abnormal body, and Y = the normative body, then one may consider the negation of embodied logic this way:

In other words, all embodiment is disjunction.

When I was a boy I watched a neighbor’s cat patiently eat a fish down to the bone. The cat allowed me, a legally blind usurper, to lie next to her as she took care of the material implications of endurance. Even before I knew the proper term, I understood algebra.

Leap: I love those lines by Dorothy Allison, from her memoir One or Two Things I Know for Sure:
“My sisters’ faces were thin and sharp, with high cheekbones and restless eyes, like my mama’s face, my aunt Dot’s, my own. Peasants, that’s what we are and always have been. Call us lower orders, the great unwashed, the working class, the poor, proletariat, trash, lowlife and scum.”

The associativity of “scum” is what’s called a “monotone” law in Boolean Algebra. Just thought this worth sharing…

We are old friends, the crippled body and I.
I’m counting all the distributive names of identity while sailing to my star.
