THE FUNDAMENTAL RELATIONSHIP BETWEEN LANGUAGE AND THOUGHT -

Given 2 (or more) pieces of data or thoughts (thoughts are ultimately, data), ADD them. Given some data or thought (say, X), delete a part of X (say, x) from it. But for doing this you should first see X as being composed of x and (X-x) for removing x. So another way of putting this point is that given (A+B), remove B from it. E.g. - I don't want this tree in this painting. So rephrasing the above - Given A and B, do A+B Given (A+B), remove B The above principle applies even in the case you want to combine A and some part/aspect of B to say, draw an inference or to create something or whatever. Taking an aspect of B is (2) and adding it to A is (1). It also similarly applies if you transform A to A’ since that is only repeated subtraction and addition with itself. So any package of thinking can be explained in terms of (as a collection of) the above 2 points. You cannot do anything with just A i.e. just with one piece of data. (Typically, you have some knowledge stored in your mind to combine it with and draw an inference from A).
