THe Learned Author of this Book treats in it of the Nature, Po^r- 
ers, Fund:ions,and Immortality of the foui ; delivering withal a 
folid Logick, illuftrated by various and inllruftive experiments, 
This he doth in /^?/^r parts i 
In the firjt he inquireth into the nafure^ origine and progrefs of 
knowledge in general, and fimple PercepHonm particular 5 obfer* 
ving the chief defefts of perceptions, together with their remedies. 
Attention, and Confideration, much helped by the ftudy of the Ma- 
thematicks, and by Recefs, &c. 
In the /^^-oW he treats, after the fame method, of the Judgment of 
the Mind, the height and perfeftion of humane knowledge. Where 
he difcourfes large^ly of the Cmerium and Mark of Truth, eonrifting 
principally in the clearnefs and diftinftnefs of Perception, as that, 
whereby the mind knows the congruity of its knowledge with the 
thing known. Here he taketh occalion to ^xsLmm^ Pyrrhomfme or Seep- 
tkifme, profeffed by a Sedof men that fpeak otherwife than they 
think* Which done, he endeavours to fhew not only^ whence the 
Light and Evidence of Principles flows, namely from Eternal and 
Immutable Reafons and/^(?/2'/,forming and direAing our knowledge, 
and begetting a certain and firm judgment in us j but aIfo,how we 
fliall come to fee thofe Eternal reafons or that Intrinfick Light of 
Truth. To all which he anncxeth thofe Propofitions, that are, in his 
judgment, to be efteemed for Principles and Axioms fo evident, that 
their Truth fliineth forth by themfclves, and needs no demonftration.- - 
Concluding this part with a confiderable Enumeration both oi the 
principal Caufes of Errors, (which may be refolvM into that main

In the Thlr^, he treats of Argumentmon andlts nature and brigine \\. 
of SyllogifmesandParalogifraes; and efpecially of the true way of 
Demonftratingj which latter he fo performs, that little feeras to be 
by him omitted of what hath been written by others that is. coniidera- 
bie. And lead a naked and jejune delivery of Rules fiiould prove te- 
dious to the Reader, he hath made them grateful with abundance of 
uncommon and pleafing examples • and laboured, not only in a Lo- 
gical but Phyfiological way to explain the caufc, nature, windings 
and errors of Ratiocination. Beiides,.his purpofe being to deliver 
a Logkh^ futable not only to the old Scbolaftick,but alfo to the Mo- 
dem and Experimental Philofophy he.difcourfeth copioufly and
