THe Learned Author of this Book treats in it of the Nature, Fow- 
ers, Fundionsand Immortality of the foul ; delivering withal a 
folid Logick, illuftrated by various and inllrudive experiments. 
This he doth infopir parts 5 
In the ^r/f he inquireth into the nature, origine and progrefs of 
knowledge in generaT, and fimple Perception in particular j obfer- 
ving the chief defeds of perceptions, together with their remedies 
Attention, and Confideration, much helped by the iludy of the Ma- 
thematicks, and by Recefs, &c. 
In the fecondht treats, after the fame method, of the lodgment of 
the Mind, the height and perfedion of humane knowledge. Where 
he difcourfes largeiy of the Critermm and Mark of Truth, confifting 
principally in the clearnefs and diftindnefs of Perception, as that, 
whereby the mind knows the congruity of its knowledge with the^ 
thing known. Here he taketh occalion to examine Pj'rr/?*?^^^' or Ssep- 
ticifme, profeffed by a Sed of men that fpeak otherwife than they 
think. Which done, he endeavours to Oiew notonly^ whence the 
Light and Evidence of Principles flows, namely from Eternal and^ 
Immutable Reafons and /^^^^x, forming and direding our knowledge, 
and begetting a certain and firm judgment in us but airo,how we^ 
lhall come to fee thofe Eternal reafons or that Intriniick Light of 
Truth. To all which he anneseth thofe Propofitiom, that are, in his 
judgment, to be efteemed for Principles and Axioms fo evident, that 
their Truth Ikineth forth by themfelvcs, and needs no demonflratson ° 
Concluding this part with a confiderable Enumeration both the 
principal Caufes of Errors, (which may be refolv*d into tharmno' 
one, the Confufim of Perceptions, hrctdlng either a hafty and un advifed,, 
or a falfe judgment,;» and of the Remedies.of thefame. 
In the Third, he treats of Argnmentation and its nature and origine v 
of Syllogifmes and Paralogifraes; and efpecially ot the true way oi: 
Demonrtrating? which latter he fo performs, that little feeras to be 
by him omitted of what hath been written by others that is coniidera- 
ble. And ieaft a naked and jejune delivery of Rules Oiould prove te- 
dious tothe Reader, he hath made them grateful with abundance of 
uncommon and'pleafing examples ; and l aboured, not only in a Lo~ 
gical but Phyflological way to explain the caufc, nature, windings 
and errors of Ratiocination. Beiides, his purpofe being to deliver 
a Logick^. futabie not only to the old ScbolaiUckjbut alfo to the Mo- 
dern and Experimental Philofophy he difcourfeth copiauily and. 
inftrudively of Induction ; fliewing from the Excellent Lord of Ve- 
rPiUm^ and the Illuftrious Robert Boyle^ how Natural Fhilofophy and^ 
all ufeful Arts may be improved and advanced by the hitherto too 
much i
