Of this vice, as of all others, every man who indulges it is conscious: we all know our own state, if we could be induced to consider it, and it might perhaps be useful to the conquest of all these ensnarers of the mind, if, at certain stated days, life was reviewed. Many things necessary are omitted, because we vainly imagine that they may be always performed; and what cannot be done without pain will for ever be delayed, if the time of doing it be left unsettled. No corruption is great but by long negligence, which can scarcely prevail in a mind regularly and frequently awakened by periodical remorse. He that thus breaks his life into parts, will find in himself a desire to distinguish every stage of his existence by some improvement, and delight himself with the approach of the day of recollection, as of the time which is to begin a new series of virtue and felicity. No. 156. SATURDAY, SEPTEMBER 14, 1751. _Nunquam aliud Natura, aliud Sapientia dicit_. Juv. Sat. xiv. 321. For Wisdom ever echoes Nature's voice. Every government, say the politicians, is perpetually degenerating towards corruption, from which it must be rescued at certain periods by the resuscitation of its first principles, and the re-establishment of its original constitution. Every animal body, according to the methodick physicians, is, by the predominance of some exuberant quality, continually declining towards disease and death, which must be obviated by a seasonable reduction of the peccant humour to the just equipoise which health requires. In the same manner the studies of mankind, all at least which, not being subject to rigorous demonstration, admit the influence of fancy and caprice, are perpetually tending to errour and confusion. Of the great principles of truth which the first speculatists discovered, the simplicity is embarrassed by ambitious additions, or the evidence obscured by inaccurate argumentation; and as they descend from one succession of writers to another, like light transmitted from room to room, they lose their strength and splendour, and fade at last in total evanescence. The systems of learning therefore must be sometimes reviewed, complications analyzed into principles, and knowledge disentangled from opinion. It is not always possible, without a close inspection, to separate the genuine shoots of consequential reasoning, which grow out of some radical postulate, from the branches which art has ingrafted on it. The accidental prescriptions of authority, when time has procured them veneration, are often confounded with the laws of nature, and those rules are supposed coëval with reason, of which the first rise cannot be discovered.
