Conceptual vs Perceptual

Our identities belong permanently to the conceptual world. They can’t be seen, heard, smelled, touched or tasted. They’re merely ideas. And everything else — at the start — belongs to the sensual world, the world outside us.

Gradually we reach beyond ourselves.

We encounter the sight, smell, touch, taste and sound of our own bodies.

And of the world around us.

And we discover that objects of the physical world can also cross over —

— and possess identities of their own.

Or, as our extensions —

— begin to glow —

— with the life —

— we lend to them.

We create the $data array and associate the key (name in the former case, city in the latter) with the actual element, and let ksort take care of the rest. ksort sorts an array by the key while maintaining the association.

The Happy Man

Once upon a time there was a scientist who wished to learn about the cause of complete happiness. Somehow he got his hands on a machine which could bring back people from the future. He traced the brain signatures of a number of candidates before selecting one whose aura had the radiance similar to his findings. The machine communicated to the subject in a unique fashion: it offered them the choice of going back in time while they dreamt of things that could have been.

The Time Machine

He narrowed it down to a subject who showed exemplary satisfaction with his life. The fact that the subject refused the chance to come back to make things right reinforced the scientist’s faith as to the appropriateness of his choice. After a lot of coaxing, he finally got him to visit his past: the scientist’s present.
