But in proceeding to the next point on which he ventures to offer some suggestions, that of BOOKS and STUDIES, we shall do well to take with us that general doctrine of _cure_, founded upon the nature of things, which he produces under the head of the cure of the body, with a distinct allusion to its proper application here. And it is well to observe how exactly the tone of the criticism in _this department_, chimes in with that of the criticism already reported here. 'In the consideration of the _cures of diseases_, I find a deficiency in the receipts of _propriety_ respecting the _particular_ cures of diseases; for the physicians _have frustrated the fruit of tradition, and experience_, by their _magistralities_ in _adding and taking out_, and changing _quid pro quo_ in their receipts _at their pleasure_, COMMANDING SO OVER THE MEDICINE, as the medicine _cannot command over the disease_:' that is a piece of criticism which appears to belong to the general subject of cure; and here is one which he himself stops to apply to a different branch of it. 'But, lest I grow more particular than _is agreeable_, either to my intention or _proportion_, I will conclude this part with the note of one deficiency more, which seemeth to me of GREATEST consequence, which is, that the _prescripts_ in use are too COMPENDIOUS TO ATTAIN THEIR END; for, to my understanding, it is a vain and flattering opinion to think any _medicine_ can be so sovereign, or so happy, as that the receipt or use of it can work any great effect upon the body of man: it were a strange _speech_, which spoken, or spoken oft, should reclaim a man from a vice to which he were _by nature subject_; it is _order, pursuit, sequence, and interchange of application_ WHICH IS MIGHTY IN NATURE,' (and it is _power_ we are inquiring for here) 'which, although it requires more exact _knowledge_ in prescribing, and more precise _obedience_ in observing, yet it is recompensed with the magnitude of effects.' Possessed now of his general theory of cure, we shall better understand his particular suggestions in regard to these medicines and alteratives of the mind and manners, which are here under consideration.
