“Enq: This means that you reject the philosophy of Spiritualism in toto?
Theo: If by “philosophy” you mean their crude theories, we do. But they have no philosophy, in truth. Their best, their most intellectual and earnest defenders say so. Their fundamental and only unimpeachable truth, namely, that phenomena occur through mediums controlled by invisible forces and intelligences – no one, except a blind materialist of the “Huxley big toe” school, will or can deny.
With regard to their philosophy, however, let me read to you what the able editor of Light, than whom the Spiritualists will find no wiser nor more devoted champion, says of them and their philosophy. This is what “M.A Oxon”, one of the very few philosophical Spiritualists, writes, with respect to their lack of organization and blind bigotry:
It is worth while to look steadily at this point, for it is of vital moment. We have an experience and a knowledge beside which all other knowledge is comparatively insignificant.
The ordinary Spiritualist waxes wroth if anyone ventures to impugn his assured knowledge of the future and his absolute certainty of the life to come.
Where other men have stretched forth feeble hands groping into the dark future, he walks boldly as one who has a chart and knows his way. Where other men have stopped short at a pious aspiration or have been content with a heredity faith, it is his boast that he knows what they only believe, and that out of his rich stores he can supplement the fading faiths built only upon hope.
He is magnificent in his dealings with man’s most cherished expectations. “You hope”, he seems to say, “for that which I can demonstrate. You have accepted a traditional belief in what I can experimentally prove according to the strictest scientific method. The old beliefs are fading; come out from them and be separate. They contain as much falsehood as truth.
Only by building on a sure foundation of demonstrated fact can your superstructure be stable. All round you old faiths are toppling. Avoid the crash and get you out.
“When one comes to deal with this magnificent person in a practical way, what is the result? Very curious and very disappointing. He is so sure of his ground that he takes no trouble to ascertain the interpretation which others put upon his facts.
The wisdom of the ages has concerned itself with the explanation of what he rightly regards as proven; but he does not turn a passing glance on its researches. He does not even agree altogether with his brother Spiritualist.
It is the story over again of the old Scotch body who, together with her husband, formed a “kirk”. They had exclusive keys to Heaven, or, rather, she had, for she was “na certain aboot Jamie.” So the infinitely divided and subdivided and resubdivided sects of Spiritualists shake their heads, and are “na certain aboot” of one another.
Again, the collective experience of mankind is solid and unvarying on this point that union is strength, and disunion a source of weakness and failure. Shoulder to shoulder, drilled and disciplined, a rabble becomes an army, each a man a match for a hundred of the untrained men that they may be brought against it.
Organization in every department of man’s work means success, saving of time and labor, profit and development. Want of method, want of plan, haphazard work, fitful energy, undisciplined effort – these mean bungling failure.
The voice of humanity attest the truth. Does the Spiritualist accept the verdict and act on the conclusion? Verily, no. He refuses to organize. He is law unto himself, and a thorn in the side of his neighbors.” – Light, June 22, 1889.”
