20361 | We need 'unities' for reckoning, but that does not mean they exist [Nietzsche] |
Full Idea: We need 'unities' in order to be able to reckon: that does not mean we must suppose that such unities exist. | |
From: Friedrich Nietzsche (The Will to Power (notebooks) [1888], §635) | |
A reaction: True. I takes this thought to be important in the Psychology of Metaphysics (an unfashionable branch). |
4533 | Logic and maths refer to fictitious entities which we have created [Nietzsche] |
Full Idea: Logic (like geometry and arithmetic) applies only to fictitious entities that we have created. | |
From: Friedrich Nietzsche (The Will to Power (notebooks) [1888], §516) | |
A reaction: This finds Nietzsche on the relativist wing of logical empiricism. The thing is, fictitious entities can have a close relationship with truth, as in a great novel. I believe in necessary logical truth, but there are many ways of slicing it. |
