Principal Figure
After all, our exploration of the concept of abstraction simply shed some light from a different angle on exactly that what we previously called “act of knowing”. All knowledge is, in some ways, abstraction. Or, more generally, representation. It is always about some extraction of what is deemed essential, and its projection onto another plane, into another space, into another dimension. What, as previously shown, can be illustrated as a pyramid.
Another way of achieving knowledge is called “perception”. And this too can perfectly be described with almost the same words, so that the same pattern becomes recognizable — the principal figure of knowledge, so to speak.
