He whose faith never doubted, may justly doubt of his faith.

I use the Scriptures, not as an arsenal to be resorted to only for arms and weapons, but as a matchless temple, where I delight to be, to contemplate the beauty, the symmetry, and the magnificence of the structure, and to increase my awe, and excite my devotion to the Deity there preached and adored.

The veneration, wherewith Men are imbued for what they call Nature, has been a discouraging impediment to the Empire of Man over the inferior Creatures of God. For many have not only look'd upon it, as an impossible thing to compass, but as something impious to attempt.

And let me adde, that he that throughly understands the nature of Ferments and Fermentations, shall probably be much better able than he that Ignores them, to give a fair account of divers Phænomena of severall diseases (as well Feavers and others) which will perhaps be never throughly understood, without an insight into the doctrine of Fermentation.

It is not strange to me that persons of the fair sex should like, in all things about them, the handsomeness for which they find themselves most liked.

The generality of men are so accustomed to judge of things by their senses that, because the air is indivisible, they ascribe but little to it, and think it but one remove from nothing.

The inspired and expired air may be sometimes very useful, by condensing and cooling the blood that passeth through the lungs; I hold that the depuration of the blood in that passage, is not only one of the ordinary, but one of the principal uses of respiration.
