| As formulated, the account would appear to admit of counterexamples. |
| And more counterexamples are coming in over the transom all the time. |
| In Proofs and Refutations, Lakatos gave several basic rules for finding proofs and counterexamples to conjectures. |
| I suppose there must be plenty of counterexamples to such a sweeping statement, but none occur to me offhand. |
| The inadequacy of the correlation coefficient is illustrated with two counterexamples. |
| That is, it is necessary to check whether a run is Zeno so as to avoid presenting Zeno runs as counterexamples. |
