If the journal is online, I will read with interest and if it is not, might
you provide a pdf,

I was starting from the cane and hammer examples, for which the glasses
metaphor does
not work well, at least for me.

When the blind man picks up the cane, it is not transparent and the mind, in
Bateson's rendering of the
discussion, stops at the fingers and palm of the hand. But with habitual
use, the "mind" or the "mind's eye"
moves to the end of the stick, to the sidewalk at its tip, and then even
further outward when walking on a
habitual path.... I can find an electronic version of the example if it is
not familiar. I would need to go to
the library to get Heiddeger.

What is it that makes the stick, as it were, become transparent, or the
handle of the hammer? Or, in the
case of the spike, that it is "seen through" to its source?
