an only hear these as a
musical sound; the next octave is four, then two, and then one
vibration in a second. But we do not stop there; the octave below
this is one vibration in two seconds, then in four seconds, eight
seconds, sixteen seconds, and so on, until it is possible to conceive
that even one frequency in a million years might be appreciated as a
musical sound, or even as one of the colours of the spectrum, by a
being whose time sensations were enormously extended in both
directions, but still finite.

Once more we must call a halt. Our finite minds become bewildered in
attempting even to glance at these infinities of time.

We measure space by miles, yards, feet, and inches; we measure time by
years, hours, minutes, and seconds; and by these finite units we try
to fathom these two marvellous infinities. With our greatest efforts
of thought we find, however, that we can get relatively no distance
whatever from the HERE of Space and the NOW of Time. It is true that
the present, as a mathematical point, appears to be hurrying and
bearing us with it along the line stretching from the past to future
eternity, but in reality we get no further from the one nor nearer to
the other. Let us change our view and examine this subject under a
different aspect.

First of all, look round a room and note the different objects to be
seen. Even in a small room we do not see the objects as they really
_are_ at this instant, but only as they _were_ at a certain fixed
length of time ago. The present time is common to every point in space
and each person is in the present, but only to his own perception; to
everyone else in the room, each individual is, at this moment, being
seen acting in the past; those objects which are further away are
being seen further behind in point of time than those that are nearer;
in fact, however near we are to an object, we can never see it as it
is but only as it was. We are dealing with very minute differences
here, they being based upon the rate at which light travels; but they
are differences which are known with a wonderful degree of accuracy.

We have here another example of how perception without knowledge leads
to false concepts. When anyone views an extended landscape, he thinks
that his sight shows him that the same point of Time, which he is
experiencing, is common to every man, animal, plant, or material
visible there, but we know now that he is seeing every part of that
scene in the p
