y and perfection in the union,
otherwise imperceptible by him, there is no reason why this difference
in faith should make him despise or quarrel with his materialist
co-worker, for the latter may do as good service to science, may be as
true a man, and live as holy a life, although from other motives.

The differences between religious sects are mainly of faith, not of
works, and the wise of all denominations are gradually coming to the
conviction that they will all do God more service by toleration and
co-operation than by animosity and disunion. And so I hold that, until
the spiritualist feels himself able to demonstrate to the unbeliever the
existence of spirit and of God, as convincingly as a mathematical
proposition, there should be no hard words or feelings upon these
points. For the present they are immaterial in every sense of the word;
and so long as he bows to the facts and the laws of Nature, and deals
with his fellow men as he would be done by, so long will I work with
him, side by side, knowing, even though I cannot tell him so, that
whether or not he joins me in this world, we shall meet in the other
world to come, where his eyes will be opened, and where his lips will at
least acquit me of bigotry and intolerance."

CHAPTER XV.

THE HUMAN TEMPERAMENTS.

Organization implies vital energy, since there can be no organization
without it. The sperm cell, as we have previously seen, exists before
the initiation of the life of every individual organism. The early
history of this fertilizing cell, which is composed of infinitesimal
molecules which contain the embryo powers of life, is only partially
written. It is a fact, authenticated by Faraday, that one drop of water
contains, and may be made to evolve, as much electricity as, under a
different mode of display, would suffice to produce a lightning-flash.
Chemical force is of a higher order than physical, and vital force is of
a still higher order. Within the microscopic compass of the sperm cell
are a great number of forces acting simultaneously, which require the
answering conditions of a germ cell, and are so blended as to occupy a
minimum of space. The union of these subtle elements through the agency
of their physical, chemical, and vital forces, constitutes the
initiation of life. Elementary matter is transformed into chemical and
organic compounds, by natural forces, upon the cessation of which, it
