The excellent qwuote above is from Thomas Browne, not Bacon, and in context it supports the wide admission of variable qualities of effort:

It is the common wonder of all men, how, among so
many millions of faces, there should be none alike:
now, contrary, I wonder as much how there should be
any.  He that shall consider how many thousand
several words have been carelessly and without study
composed out of twenty-four letters; withal, how many
hundred lines there are to be drawn in the fabrick of
one man; shall easily find that this variety is necessary:
and it will be very hard that they shall so concur as to
make one portrait like another.  Let a painter carelessly
limn out a million of faces, and you shall find them all
different; yes, let him have his copy before him, yet,
after all his art, there will remain a sensible distinction:
for the pattern or example of everything is the perfectest
in that kind, whereof we still come short, though we
transcend or go beyond it; because herein it is wide,
and agrees not in all points unto its copy.  Nor doth
the similitude of creatures disparage the variety of
nature, nor any way confound the works of God.
