masses; they are each shielding the other from
Ether pressure, in its own direction, with an obstructive force equal
to its mass. The reason why the earth appears to attract us, is that
it is shielding us from a certain amount of pressure in its direction;
and we know that we are also apparently attracting every particle of
the earth with a force proportionate to our mass, because we are,
however slightly, shielding the earth from pressure in our direction;
if this is the true explanation, Gravitation is a phenomenon of the
Ether; it will be seen to be a movement of matter in the line of least
pressure, and is therefore a push and not a pull.

Let us now come down to what we understand better concerning the
subject of this View.

The question, "What is Truth?" "What is the Reality?" goes to the very
root of the Riddle of the Universe. We are all trying in one direction
or another to answer this question. As knowledge increases, old
theories become untenable and have to be discarded, and, in their
place, fresh ones are formulated to account for new phases of
phenomena. There seems a general impression, among even thinking
people, that scientists are wedded to, and always trying to find
proofs for, their last theories, but this is not the case. The
endeavour of the true seeker after truth is not so much to discover
fresh facts which coincide with existing theories, as to find
phenomena which cannot be explained thereby; there is indeed more joy
over one fact which does not agree with preconceived theory, than over
ninety-nine facts which are found to fall under that heading. In our
everyday life we have become so accustomed to take for granted that
what we see, hear, or feel by touch must be real, that it is difficult
for the man in the street to realise that our senses woefully deceive
us; that perception without knowledge often leads us astray into false
concepts, and these false concepts lead us into difficulties which
require fresh concepts to be formed, and these again demand further
and more exact knowledge to be applied to perceived phenomena. This
necessity for overcoming difficulties is the greatest incentive we
have for gaining fresh knowledge of our surroundings. Owing to the
fact, as already pointed out, that our sense perceptions are based
upon the appreciation of change or motion, and must therefore be
limited in Time and Space, and that the trueness of our conceptions of
the Reality is dependent upon the
