I rarely comment on these incidental aphorisms, but this one is so wrong
that it is worth pointing out. You can confirm the existence of many bugs
by
* demonstration via failing test case,
* finding the bug,
* having a plausible explanation for why it is incorrect,
* writing a fix with a plausible explanation for why it fixes the
problem, and
* demonstrating that the fix repairs the demonstrated test case.
However hard this is, it is vastly easier than confirming that there are no
bugs in your own code.
