- Obviously. I am doing some non-standard analysis myself, so I
- am not trying to ask a philosophically sceptical question along
- the lines of Descartes whether there really exists something
- called "non-standard analysis" or whether there's just an evil
- demon seducing me to believe so.
-
- What I wanted to know is under which philosophies NSA is a valid
- type of mathematics. Finitists, as mentioned above, surely will
- find it to be non-valid mathematics, and perhaps just nonsense.
- I don't care too much about them, but since I wonder a little
- about the philosophical justifications and validations for what
- I am actually doing myself, I wanted to know what was (philosophically)
- needed to say NSA is valid. It will affect both my choice of philosophy
- and my approach to NSA. [NSA Non Standard Analysis.]
