Coincidences, in general, are great stumbling blocks in the way of that class of thinkers who have been educated to know nothing of the theory of probabilities- that theory to which the most glorious objects of human research are indebted for the most glorious of illustration.
Edgar Allan PoeAnd because our reason violently deters us from the brink, therefore, do we the more impetuously approach it. There is no passion in nature so demoniacally impatient, as that of him, who shuddering upon the edge of a precipice, thus meditates a plunge. To indulge for a moment, in any attempt at thought, is to be inevitably lost; for reflection but urges us to forbear, and therefore it is, I say, that we cannot. If there be no friendly arm to check us, or if we fail in a sudden effort to prostrate ourselves backward from the abyss, we plunge, and are destroyed.
