Beginners are apt to confound the notion of the whole content
Area confounded
with the Boundaries
of Figures or Area of a figure with that of the mere boundaries. The
idea I used to have of the Square of a Line (and I know in
this I was not Singular) was four times that line;
because it had four such Lines for its boundaries, and those
boundaries only are represented to the Eye. In a Circle,
in like manner, I used to consider nothing but the
circumference: so that the Ideas of the word Circle and
circumference of a Circle were the same. This is not by
any means to be wondered at: how should the Idea of
the learner be otherwise than confused, when that of the
Master is no better? Many are the instances in which
the Ideas of a Circle and its CIrcumference, and of the
boundaries of Triangles and their Areas, stand confounded,
as well by Euclid as by all his Editors.
