Finitism? Really ? What about induction? And more importantly ,who

gets to decide how large a number is 'enough'?And by what criteria?

This is the most important question regarding finitism . You can't

just wish it away . Should we play "who can think of the largest

number"?

If reality were finite , then our infinite mathematics would certainly

be enough to model it , as it includes all finite models .

On the other hand , if reality were infinite , only an infinite

mathematics would suffice for it .

"If the doors of perception were cleansed every thing would appear to

man as it is, infinite. For man has closed himself up, till he sees

all things through narrow chinks of his cavern." -William Blake
