'Blind thought' is reasoning without recognition of the ingredients of the reasoning
|
|
|
|
Full Idea:
Leibniz invented the concept of 'blind thought' - reasoning by a manipulation of characters without being able to recognise what each character stands for.

We can assign a characteristic number to every single object
|
|
|
|
Full Idea:
The true principle is that we can assign to every object its determined characteristic number.

A reaction:
I add this as a predecessor of Gödel numbering. It is part of Leibniz's huge plan for a Universal Characteristic, to map reality numerically, and then calculate the truths about it. Gödel seems to allow metaphysics to be done mathematically.

Everything is subsumed under number, which is a metaphysical statics of the universe, revealing powers
|
|
|
|
Full Idea:
There is nothing which is not subsumable under number; number is therefore a fundamental metaphysical form, and arithmetic a sort of statics of the universe, in which the powers of things are revealed.

A reaction:
I take numbers to be a highly generalised and idealised description of an aspect of reality (seen as mainly constituted by countable substances). Seeing reality as processes doesn't lead us to number. So I like this idea.
