A good deal of this rests upon the Platonic ideology, which maintained that any material object was an impure and imperfect copy of some ideal perfection. So men who wished to advance in spiritual science and philosophy strove always to formulate for themselves the Pure Idea. They tried to proceed from the Particular to the General; and this principle has been of the greatest service to ordinary science. The mathematics of 6+5=11, and 12+3=15, was all in bits. Advance only came when they wrote down their equations in general terms. X²-Y²=(X+Y)(X-Y) covers all possible cases of subtracting the sqaure of one number from the square of another. So the Meaningless and Abstract, when understood, has far more meaning than the Intelligible and Concrete.
