"Faith may be defined briefly as an illogical belief in the occurrence of the improbable"

In this quote, H. L. Mencken is suggesting that faith is an illogical belief in something that is unlikely to occur. He is implying that faith is not based upon reasoning or factor, however rather on a strong conviction that something will take place, even if it is extremely improbable. This could be interpreted as a criticism of faith, as it indicates that faith is not based on evidence or realities, but rather on a strong belief in something that is not likely to happen. However, it might likewise be seen as a favorable statement, as it suggests that faith is a powerful force that can cause the realization of the improbable. Eventually, this quote suggests that faith is an effective force that can result in the realization of the improbable, even if it is not based upon logic or factor.
