Luck, if it mean nothing more than an event of which the cause is not apparent, is a term that may be employed without error; but if it means, as it generally does, an event which has no cause at all, a mere chance, it is a bad word, a heathen term; drop it from your vocabulary; trust nothing to luck, nor expect anything from it; avoid all practical use or dependence upon this or its kindred words, fate, chance, fortune.
