But, you may say, this is very interesting, but it is not clairvoyance. Certainly, good student, but still clairvoyance plays an important part even in this elementary form of prevision and future-seeing. You must remember that by clairvoyant vision the real thoughts and feelings of a person may be perceived. But, unless the attention of the clairvoyant is specially directed to this, the conscious mind does not note it, and the matter reaches the subconscious faculties without interference or conscious knowledge on the part of the clairvoyant. This being so, it will be seen that the subconscious mind of the clairvoyant is able to reason deductively, in such cases, far beyond the power of even the subconscious mind of the ordinary person--it has fuller data and more complete material to work upon, of course. It has become a proverb of the race that "coming events cast their shadows before"; and many persons frequently have little flashes of future-time seeing without realizing that they are really exercising elementary clairvoyant powers. The combination of even a simple form of clairvoyance and an active subconscious mind will often produce very wonderful results--although not of course the more complex phenomena of full clairvoyance and prevision. Some persons have claimed that even this form of prevision implies something like fate or predestination, but this is not fully true, for we must remember the fact that in some cases it is possible to so act in accordance with a clairvoyant warning of this kind that the impending calamity may be escaped. But, on the other hand, we must also remember that every event is the result of certain preceding events, without which it could not have happened, and which existing it must happen unless some new element intervenes. There is such a thing as cause and effect, we must remember--and if we can reason clearly from one to the other with sufficient clearness, then we may actually prophesy certain things in advance, always making allowance for the intervention of the unexpected.
