F all the human Sciences, that concerning Man, is certainly the moft worthy of Man, and the moft neceffary Part of Knowledge. We find ourfelves in this World furrounded with a Variety of Objects; we have Powers and Faculties fitted to deal with them, and are happy or miferable in proportion as we know how to frame a right Judgment of Things, and shape our Actions agreeably to the Circumftances in which we are placed. No Study therefore is more important than that which introduces us to the Knowledge of ourselves. Hereby we become acquainted with the Extent and Capacity of the human Mind, and learning to diftinguish what Objects it is fuited to, and in what manner it must proceed, in order to compafs its Ends, we arrive by degrees at that Juftnefs and Truth of Understanding, which is the great Perfection of a rational Being.
Importance of the Kno ledge of ourfelves.
II. If we look attentively into Things, and furvey them in their full Extent, we fee them rifing one above another in various Degrees of Eminence. Among the inanimate Parts of Matter fome exhibit nothing worthy our Attention, their Parts feem as it were jumbled together by mere Chance,
nor can we difcover any Beauty, Order, or Regularity in their Compofition. In others we difcern the finest Arrangement, and a certain Elegance of Contexture, that makes us affix to them a Notion of Worth and Excellence. Thus Metals, and precious Stones, are conceived as far furpaffing thofe unformed Mafics of Earth, that lie every where expofed to view. If we trace Nature onward, and pursue her through the vegetable and animal Kingdoms, we find her ftill multiplying her Perfections, and rifing by a juft Gradation, from mere Mechanifm to Perception, and from Perception in all its various Degrees, to Reafon and Understanding.
III. BUT though Reafon be the Boundary, by Usefulness of Culture, and which Man is diftinguifhed from the other Creaparticularly tures that furround him, yet we are far from of the Study finding it the fame in all. Nor is this Inequality of to be wholly afcribed to the original Make of Men's Minds, or the Difference of their natural Endowments. For if we look abroad into the feveral Nations of the World, fome are over-run with Ignorance and Barbarity, others flourish in Learning and the Sciences; and what is yet more remarkable, the fame People have, in different Ages, been diftinguished by thefe very oppofite Characters. It is therefore by Culture, and a due Application of the Powers of our Minds, that we increase their Capacity, and carry humart Reafon to Perfection. Where this Method is followed, Knowledge and Strength of Understanding never fail to enfue; where it is neglected, we remain ignorant of our own Worth and thofe latent Qualities of the Soul, by which the is fitted to furvey this vaft Fabrick of the World, to scan the Heavens, and fearch into the Caufes of Things, lie buried in Darkness and Obfcurity. No Part of Knowledge therefore yields a fairer Profpect of Improvement, than that which takes account of the Understanding, examines its Powers and Faculties, and fhews the Ways by which it comes to attain its various Notions of Things. This is properly the Defign of Logick, which may be juftly filed the Hiftory of the human Mind, inafinuch as it traces the Progrefs of our Knowledge, from our first and fimple Percepfions, through all their different Combinations, and all thofe numerous Deductions that refult from variously comparing them one with another. It is thus that we are let into the natural Frame and Contexture of our own Minds, and learn in what manner we ought to conduct our Thoughts, in order to arrive at Truth, and avoid Error. We fee how to build one Difcovery upon another, and by preferving the Chain of
