 ANALYSIS OF THE ADVANCEMENT OF LEARNING. . Pure mathematics cure many intellectual defects. / the wit be too dull, they sharpen it ; if too wandering, they fix it .- // too inherent in the sense, they obstruct it. -So that as tennis is a g&amp;lt;t me of no use in itself, but of great use in respect it maketh a {/uick eye and a body ready to put itself into all postures, so in the mathematics, that use which is collateral and intervenient is no less worthy than that which is principal and intended. Mixed Mathematics 199 . Its subject is some axioms or points of natural phi losophy, and considers quantity determined, as auxiliary and incident to them, as perspective, music, architecture, &c. . They will increase as nature is more disclosed. OPERATIVE NATURAL PHILOSOPHY. . It is the production of effects. . Division. . Experimental. . Philosophical. . Magical. .

The voice of nnfure will consent, wh thcr the voice of man do or not. And us A/exan der Borgia was wont to say of the expeditioi of the French for Naples, that they came wit) chalk in their hands to mark up their lodging* and not with weapons to fight : so I like bet ter that entry of truth which comet h peace a dy, with chalk to mark up those mina which are capable to lodge and harbour i than that which Cometh with pugnacity an contention.

That use of wit and knowledge is to be lowed, which luboureth to moke doubtfi things certain, and nut those which labo make certain things doubtful. Of a Calendar of Popular Errors. General doubts, or those differences of opinions, touc ing the principles of nature which have cause the diversities of sects 2( Thus have we now dealt with two of t thru, beams of man s knowledge,- that &quot;Radius directus,&quot; which is referred to nature, &quot;Radius refrucfits,&quot; which is referred to God,- and cannot report truly bf cause of the inequa lity of the medium; there rexteth &quot; Radius reflexux&quot; whereby man belioldeth and contem- plateth himself. DGE OV The knowledge of men deserves more accurate in vestigiUion, because it touches us more nearly. The knowledge of man is to man the end of all knowledge: but of nature herself a portion only. All partitions of knowledge should be ac cepted rather for lines and veins, than for sections and separations ; that the. continuance and entireness of knowledge be preserved. Division of human philosophy. . Man as an individual. . Man as a member of society. MAN AS AN INDIVIDUAL. . Division. . The undivided state of man. . Discovery. . Impression. . The divided state of man. Discovery. The art of ascertaining the state of the mind from the appearance of the body, as physiognomy, &c. !. The art of ascertaining the state of the body from the appearance of the mind, as exposition of dreams, &c. Physiognomy ............ 201 . The discovery of the mind from the appearance of the body. . Aristotle has laboured physiognomy as far as relates to the countenance at rest; but not when in motion. . The lineaments of the body disclose the general in clinations of the mind : the motions its present dispositions. A number of subtle persons, whose eyes do dwell upon the faces and fashions of men, do well know the advantage of this observation, as being most part of their ability. Impression. . It is the science of the relative action of the body and mind upon each other. . Of the action of the body on the mind. . This has been inquired as a part of medicine. 2. The doctrine that the body acts upon the mind does not derogate from the sou. s dignity. The infant in the mother s womb is com patible with the mother and yet separable , and the most absolute monarch is fome/imea led by his servants and yet without subjection. . The action of the mind on the body. . Physicians have ever considered &quot; acciden- tia animi,&quot; as of great importance. . The power of imagination as well to help as to hurt is a subject neglected, but de serving inquiry. It cannot be concluded that because there be pestilent airs, able suddenly to kill a man in See note (P) at the end of this Treatise
