21. Contrary Principles in the World.
I easily grant that there are great numbers of opinions
which, by men of different countries, educations, and tempers, are received and
embraced as first and unquestionable principles; many whereof, both for their
absurdity as well as oppositions to one another, it is impossible should be
true. But yet all those propositions, how remote soever from reason are so
sacred somewhere or other, that men even of good understanding in other
matters, will sooner part with their lives, and whatever is dearest to them,
than suffer themselves to doubt, or others to question, the truth of them.
22. How men commonly come by their Principles.
This, however strange it may seem, is that which every
day’s experience confirms; and will not, perhaps, appear so wonderful, if we
consider the ways and steps by which it is brought about; and how really it may
come to pass, that doctrines that have been derived from no better original
than the superstition of a nurse, or the authority of an old woman, may, by
length of time and consent of neighbours, grow up to the dignity of PRINCIPLES
in religion or morality. For such, who are careful (as they call it) to
principle children well, (and few there be who have not a set of those
principles for them, which they believe in,) instil into the unwary, and as yet
unprejudiced, understanding, (for white paper receives any characters,) those
doctrines they would have them retain and profess. These being taught them as
soon as they have any apprehension; and still as they grow up confirmed to
them, either by the open profession or tacit consent of all they have to do
with; or at least by those of whose wisdom, knowledge, and piety they have an
opinion, who never suffer those propositions to be otherwise mentioned but as
the basis and foundation on which they build their religion and manners, come,
by these means, to have the reputation of unquestionable, self-evident, and
innate truths.
23. Principles supposed innate because we do not remember
when we began to hold them.
To which we may add, that when men so instructed are
grown up, and reflect on their own minds, they cannot find anything more
ancient there than those opinions, which were taught them before their memory
began to keep a register of their actions, or date the time when any new thing
appeared to them; and therefore make no scruple to conclude, that those
propositions of whose knowledge they can find in themselves no original, were
certainly the impress of God and nature upon their minds, and not taught them by
any one else. These they entertain and submit to, as many do to their parents
with veneration; not because it is natural: nor do children do it where they
are not so taught; but because, having been always so educated, and having no
remembrance of the beginning of this respect, they think it is natural.
24. How such principles come to be held.
This will appear very likely, and almost unavoidable to
come to pass, if we consider the nature of mankind and the constitution of
human affairs; wherein most men cannot live without employing their time in the
daily labours of their callings; nor be at quiet in their minds without SOME
foundation or principle to rest their thoughts on. There is scarcely any one so
floating and superficial in his understanding, who hath not some reverenced
propositions, which are to him the principles on which he bottoms his
reasonings, and by which he judgeth of truth and falsehood, right and wrong;
which some, wanting skill and leisure, and others the inclination, and some
being taught that they ought not to examine, there are few to be found who are
not exposed by their ignorance, laziness, education, or precipitancy, to TAKE
THEM UPON TRUST.
25. Further explained.
This is evidently the case of all children and young
folk; and custom, a greater power than nature, seldom failing to make them
worship for divine what she hath inured them to bow their minds and submit
their understandings to, it is no wonder that grown men, either perplexed in
the necessary affairs of life, or hot in the pursuit of pleasures, should not
seriously sit down to examine their own tenets; especially when one of their
principles is, that principles ought not to be questioned. And had men leisure,
parts, and will, who is there almost that dare shake the foundations of all his
past thoughts and actions, and endure to bring upon himself the shame of having
been a long time wholly in mistake and error? Who is there hardy enough to
contend with the reproach which is everywhere prepared for those who dare
venture to dissent from the received opinions of their country or party? And
where is the man to be found that can patiently prepare himself to bear the
name of whimsical, sceptical, or atheist; which he is sure to meet with, who
does in the least scruple any of the common opinions? And he will be much more
afraid to question those principles, when he shall think them, as most men do,
the standards set up by God in his mind, to be the rule and touchstone of all
other opinions. And what can hinder him from thinking them sacred, when he
finds them the earliest of all his own thoughts, and the most reverenced by
others?
26. A worship of idols.
It is easy to imagine how, by these means, it comes to
pass that men worship the idols that have been set up in their minds; grow fond
of the notions they have been long acquainted with there; and stamp the
characters of divinity upon absurdities and errors; become zealous votaries to
bulls and monkeys, and contend too, fight, and die in defence of their
opinions. Dum solos credit habendos esse deos, quos ipse colit. For, since the
reasoning faculties of the soul, which are almost constantly, though not always
warily nor wisely employed, would not know how to move, for want of a
foundation and footing, in most men, who through laziness or avocation do not,
or for want of time, or true helps, or for other causes, cannot penetrate into
the principles of knowledge, and trace truth to its fountain and original, it
is natural for them, and almost unavoidable, to take up with some borrowed
principles; which being reputed and presumed to be the evident proofs of other
things, are thought not to need any other proof themselves. Whoever shall
receive any of these into his mind, and entertain them there with the reverence
usually paid to principles, never venturing to examine them, but accustoming
himself to believe them, because they are to be believed, may take up, from his
education and the fashions of his country, any absurdity for innate principles;
and by long poring on the same objects, so dim his sight as to take monsters
lodged in his own brain for the images of the Deity, and the workmanship of his
hands.
27. Principles must be examined.
By this progress, how many there are who arrive at
principles which they believe innate may be easily observed, in the variety of
opposite principles held and contended for by all sorts and degrees of men. And
he that shall deny this to be the method wherein most men proceed to the
assurance they have of the truth and evidence of their principles, will perhaps
find it a hard matter any other way to account for the contrary tenets, which
are firmly believed, confidently asserted, and which great numbers are ready at
any time to seal with their blood. And, indeed, if it be the privilege of
innate principles to be received upon their own authority, without examination,
I know not what may not be believed, or how any one’s principles can be
questioned. If they may and ought to be examined and tried, I desire to know
how first and innate principles can be tried; or at least it is reasonable to
demand the MARKS and CHARACTERS whereby the genuine innate principles may be
distinguished from others: that so, amidst the great variety of pretenders, I
may be kept from mistakes in so material a point as this. When this is done, I
shall be ready to embrace such welcome and useful propositions; and till then I
may with modesty doubt; since I fear universal consent, which is the only one
produced, will scarcely prove a sufficient mark to direct my choice, and assure
me of any innate principles.
From what has been said, I think it past doubt, that
there are no practical principles wherein all men agree; and therefore none
innate.[1]
