1 is not successive to 2, nor is the
to the second day of the month."Contiguous" is that which is
successive and in contact. The "continuous" is a species of the
two things continuous when their respective boundaries, by which they
are kept together in contact, become one and the same; hence clearly
the continuous belongs to the sphere of things whose nature it is to
become one by contiguity.
"successive" is the most ultimate term; for the successive need not be
in contact, but contact implies succession; and if there is continuity
there is contact, but if there is contact there is not necessarily
where there is no contact there is no coalescence. Therefore a point
is not the same as a unit; for points admit of contact, whereas units
do not, but only of succession; and between points there is something
intermediate, but between units there is not.
