The Poetics of Space
by Gaston Bachelard is a classic.
He talks about the
spaces in the home, its intimacy and cosiness, and of being enclosed (but not
shut in).
He refers to the way
that cupboards, wardrobes, boxes, shells, fruit skins, etc
both protect and make
cosy what's inside, but also arouse human
exploratory behaviour
by partly hiding their contents.

These two would have co-evolved –
'hiding' and 'exploring' driving each other's emergence.
And while this would have happened long before
humans came on the scene,
there is a theory now that a key feature
of human evolution required the
ability to find treasure where no other animal could.

As a scavenger Homo habilis would have arrived on the scene of a kill
after most of the flesh had gone, eaten by lions and hyenas.
But inside the bones there was bone marrow,
a rich source of food. But not
accessible unless one has strong jaws and teeth –
or the ability to use tools.

Chimpanzees today can be seen
opening large nuts, cracking them on a stone ‘anvil’ with another stone
- primitive tools. Homo habilis did the same for bone marrow.
Fortunately refrigerators, cash registers and
Christmas presents are easier…
