not believe to be true, only to keep themselves in reputation and esteem amongst those who are persuaded of their obligation.  But it is not to be imagined that a whole society of men should publicly and professedly disown and cast off a rule which they could not in their own minds but be infallibly certain was a law; nor be ignorant that all men they should have to do with knew it to be such:  and therefore must every one of them apprehend from others all the contempt and abhorrence due to one who professes himself void of humanity:  and one who, confounding the known and natural measures of right and wrong, cannot but be looked on as the professed enemy of their peace and happiness.  Whatever practical principle is innate, cannot but be known to every one to be just and good.  It is therefore little less than a contradiction to suppose, that whole nations of men should, both in their professions and practice, unanimously and universally give the lie to what, by the most invincible evidence, every one of them knew to be true, right, and good.  This is enough to satisfy us that no practical rule which is anywhere universally, and with public approbation or allowance, transgressed, can be supposed innate.—­But I have something further to add in answer to this objection.

12.  The generally allowed breach of a rule proof that it is not innate.

The breaking of a rule, say you, is no argument that it is unknown.  I grant it:  but the generally allowed breach of it anywhere, I say, is a proof that it is not innate.  For example:  let us take any of these rules, which, being the most obvious deductions of human reason, and conformable to the natural inclination of the greatest part of men, fewest people have had the impudence to deny or inconsideration to doubt of.  If any can be thought to be naturally imprinted, none, I think, can have a fairer pretence to be innate than this:  “Parents, preserve and cherish your children.”  When, therefore, you say that this is an innate rule, what do you mean?  Either that it is an innate principle which upon all occasions excites and directs the actions of all men; or else, that it is a truth which all men have imprinted on their minds, and which therefore they know and assent to.  But in neither of these senses is it innate.  First, that it is not a principle which influences all men’s actions, is what I have proved by the examples before cited:  nor need we seek so far as the Mingrelia or Peru to find instances of such as neglect, abuse, nay, and destroy their children; or look on it only as the more than brutality of some savage and barbarous nations, when we remember that it was a familiar and uncondemned practice amongst the Greeks and Romans to expose, without pity or remorse, their innocent infants.  Secondly, that it is an innate truth, known to all men, is also false.  For, “Parents preserve your children,” is so far from an innate truth, that it is no truth at all:  it being a command,
