- Are you saying that it can be valuable to treat an open problem AS IF
- there is a proof one way or the other, even if on occasion one may turn
- out to be wrong? I don't have any objection to this. It can also be
- valuable to treat Goldbach's conjecture AS IF it were true when trying
- to solve the problem. My point is that if pressed, most mathematicians
- I think would not claim to KNOW that Goldbach's conjecture is true or
- even decidable until they see a proof. (Conversely, if they do see a
- proof most mathematicians do not hesitate to use the word "know.") I
- concede that my use of the word "nobody" was an overstatement, though.

- Analogously, naturalism may be a convenient working assumption---i.e.,
- it may be valuable to act as if it were true---but perhaps it is safest
- to admit the possibility that it is wrong until we have something like
- a "proof" that abiogenesis occurred by naturalistic means (i.e., a highly
- plausible mechanism).
