Chirality is a super-primitive

The distinction between left and right is one of the mysteries of our universe. Certainly it is related to a line (ray of light) dividing space in two parts from the point of view of an entity, but there is no way to objectively define left as left, for example the idea of dividing the visual field in 360 degrees and assigning 0-180 to, let’s say, left, presupposes we know where left is to start numbering the angles in the right direction. It looks like chirality depends on both an inbuilt recognition mechanism, as well as a physical asymmetry that “implements” it, perhaps going all the way back to molecular chirality. In fact it seems to be a phenomenon that stretches all the way from physics into biology, as it is quite unlikely the distinction could be made without a (bicameral) asymmetric brain. In some sense chirality is a sense, that little special part of the mental world where “you know when you know”, the taste of orange being the taste of orange (I have not made up my mind if/how important it is that taste is a composite sense combining different primitives of smell and taste).
