At A Glance
If we comprehend and represent a temporal series of events or stages, a process, as a whole, then these stages come to lie side by side, establishing a spatial dimension, so to speak.
That’s all there is to it. That way we get the whole process at a glance. We know what happens, what did happen and will happen.
Spatial arrangement is the expression of knowledge, space is always a space of knowledge, and knowledge is always spatial. Knowledge is the ultimate dimension (of space).
