Mathematical propositions have no other certainty than what belongs
to the conclusions of sense: for they are themselves derived from those
conclusions: the only advantage they have is, that they
the Ideas which form this terms of which they consist are may be
taken and therefore are taken from those objects of sense, the conclusions which can
concerning which are afford conclusions, and those taken under circumstances in which they are, least liable to error — A Mathematician
takes raises his abstract ideas of a line and a circle
from the most perfect right line & circle he ever saw, and these
placed at these distances from his eye at which he is least
liable to be mistaken in their figure: and if in these he
says any defects, any parts tending to curvature in the right
line or to streightness or a different curvature in the circle he may make
his ideal line & circle free even from these imperfections which he by
resolving not to suppose them to exist: & finally he may free
them from all possible imperfections by saying to himself,
if there are any behind, which I cannot see, be they will what
they will, I will them out of the case as I do these.
Thus it is that he purifies his ideas of all the imperfections which
existed in the impressions of which they were the copies.
