The recollection of the past is only useful by way of provision for the future; and, therefore, in reviewing all occurrences that fall under a religious consideration, it is proper that a man stop at the first thoughts, to remark how he was led thither, and why he continues the reflection. If he is dwelling with delight upon a stratagem of successful fraud, a night of licentious riot, or an intrigue of guilty pleasure, let him summon off his imagination as from an unlawful pursuit, expel those passages from his remembrance, of which, though he cannot seriously approve them, the pleasure overpowers the guilt, and refer them to a future hour, when they may be considered with greater safety. Such an hour will certainly come; for the impressions of past pleasure are always lessening, but the sense of guilt, which respects futurity, continues the same. The serious and impartial retrospect of our conduct, is indisputably necessary to the confirmation or recovery of virtue, and is, therefore, recommended under the name of self-examination, by divines, as the first act previous to repentance. It is, indeed, of so great use, that without it we should always be to begin life, be seduced for ever by the same allurements, and misled by the same fallacies. But in order that we may not lose the advantage of our experience, we must endeavour to see every thing in its proper form, and excite in ourselves those sentiments, which the great Author of nature has decreed the concomitants or followers of good and bad actions. Μηδ' ὑπνον μαλακοισιν επ' ομμασι προσδεξασθαι, Πριν των ἡμερινων εργων τρις ἑκαστον επελθειν· Πηι παρεβην; τι δ' ερεξα; τι μοι δεον ουκ ετελεσθη; Αρξαμενος δ' απο πρωτου επεξιθι; και μετεπειτα, Δειλα μεν εκπρηξας, επιπλησσεο, χρηστα δε, τερπου. Let not sleep (says Pythagoras) fall upon thy eyes till thou hast thrice reviewed the transactions of the past day. Where have I turned aside from rectitude? What have I been doing? What have I left undone, which I ought to have done? Begin thus from the first act, and proceed; and in conclusion, at the ill which thou hast done be troubled, and rejoice for the good. Our thoughts on present things being determined by the objects before us, fall not under those indulgences or excursions, which I am now considering. But I cannot forbear, under this head, to caution pious and tender minds, that are disturbed by the irruptions of wicked imaginations, against too great dejection, and too anxious alarms; for thoughts are only criminal, when they are first chosen, and then voluntarily continued. Evil into the mind of God or man May come and go, so unapprov'd, and leave No spot or stain behind. MILTON.
