thrown
across from one convolution to another of the brain; a very slight
alteration would open up to our consciousness the present existence of
the future. The prime perceivable difference between our brains and
those of the Apes and lower animals is the larger number of
enfoldments, or convolutions, that are developed by the Human. Each
new line of thought, or sequence of thoughts, requires, and is
provided with, a new wrinkle or small convolution, and it probably
only requires the attention of the human race to be fixed, for a time,
on the consideration of this subject, to evolve the slight alteration,
or bridge, necessary to enable us to see that the future, as also the
past, does actually exist and is included in the Now. It may make this
a little clearer to consider that if you maintain that, in traversing
the duration of time, the future does not exist until you arrive
there, you should also in fairness insist that, in travelling through
the extension of Space, your destination, say Rome, does not exist
until you get there and can see it with your senses.

As we have, in the former six Views, been gradually mounting above the
mists and illusions of our everyday thoughts, and can look through our
Window with, I hope, a clearer vision, I shall venture in this present
View to carry the subject of the _Future_ still further, and show
that, just as we have now before us and can read the papyri which were
written 5000 years ago, so it is possible to conceive that books,
written and being written and printed 5000 years hence, are _at
present_ in existence, and that it is even possible the human race has
actually already read them; whether we shall be able to see them and
read them in our own lifetime may be open to question; that may again
depend upon the development of special cross-circuiting of brain
filaments. Meanwhile, in order to carry our present View to the utmost
limit of our conception, in a manner somewhat similar to what we did
for Space, I will again ask you to join me in a thought-flight
towards the appreciation of this second great Mystery.

With this object in view we will first consider the human senses of
sight and hearing, commencing with sound, or the vibrations which
affect the tympanum of the human ear. Sound travels in air at about
1130 feet per second, and if the vibrating body, giving out the sound,
oscillates sixteen times in one second, it follows that, spreading
over this 1130 feet, there
