It is an established opinion among some men that there are in the understanding certain innate principles --- some primary notions , koinai ennoiai¹, characters , as it were , stamped upon the mind of man , which the soul receives in its very first being and brings into the world with it. It would be sufficient to convince unprejudiced reader of the falseness of this supposition , if i should only show ( as i hope i shall in the following parts of this discourse  ) how men , barely² by the use of their natural faculties, may attain to all the knowledge they have without the help of any innate impressions, and may arrive at certainty without any such original notions or principles . For I imagine anyone will easily grant that it would be impertinent to suppose the ideas of colors innate in a creature to whom God has given sight and a power to receive them by the eyes from external objects.And no less unreasonable would it be to attribute several truths to the impressions of nature and innate characters ,  when we may observe in ourselves faculties fit to attain as easy and certain knowledge of them as if they were originally imprinted on the mind.
    But because a man is not permitted without censure to follow his own thoughts in the search of truth when they lead him ever so little out of the common road , i shall set down the reasons that made me doubt of the truth of that opinion , as an excuse for my mistake , if i be in one --- which i leave to be considered by those who, whit me, dispose themselves to embrace truth wherever they find it.

koinai ennoiai¹ : common conceptions (Greek). [ D.C.Abel ]
