Single Idea 7144

[filed under theme 5. Theory of Logic / A. Overview of Logic / 3. Value of Logic ]

Full Idea

Logic assumes identical cases exist; to think and conclude logically, the fulfilment of this condition must first be feigned. That is: the will to logical truth cannot realise itself until a fundamental falsification of all events has been undertaken.

Gist of Idea

Logic must falsely assume that identical cases exist

Source

Friedrich Nietzsche (Writings from Late Notebooks [1887], 40[13])

Book Ref

A Reaction

Interesting. This implies that the particularism espoused by virtue theorists (there are no principles, as each case is slightly different) should be extended to other branches of human understanding. So arithmetic is impossible??
