And in order to the restraining it we may consider, what a loss of Time and Study such irregular and useless Thoughts occasion, what a Reproach they are to our Reason, how they cheat us with a _shew_ of Knowledge, which so long as we are under the power of this giddy Temper will inevitably escape us. And if to this we add a serious perusal of such Books as are not loosly writ, but require an Attent and Awakened Mind to apprehend, and to take in the whole force of ’em, obliging our selves to Understand them throughly, so as to be able to give a just account of them to our Selves, or rather to some other Person intelligent enough to take it and to correct our mistakes, it is to be hop’d we shall obtain a due poise of Mind, and be able to direct our Thoughts to the thorow discussion of such Subjects as we wou’d Examine. Such Books I mean as are fuller of Matter than Words, which diffuse a light through every part of their Subject, do not Skim, but Penetrate it to the bottom, yet so as to leave somewhat to be wrought out by the Reader’s own Meditation; such as are writ with Order and Connexion, the Strength of whose Arguments can’t be sufficiently felt unless we remember and compare the whole System. ’Tis impossible to prescribe absolutely, and every one may easily find what Authors are most apt to stay their Attention, and shou’d apply to them. But whenever they Meditate, be it on what Object it may, let ’em fix their Minds stedily on it, not removing till it be throughly Examin’d, at least not until they have seen all that’s necessary to their present purpose.
