These impressions are so uncertain upon several points, that I wondered if it were worth while expressing in book form the few and sparse conclusions I am able to formulate. If, finally, I decide to publish my opinions, it is because it seems incumbent upon me to do so. I am not blind to the fact that my testimony is of very little importance; but however modest it may be, it seems to me that it is my duty to offer this testimony, such as it is, to those who have undertaken to submit to scientific discipline the study of those phenomena which are, in appearance at least, so rebellious to such discipline. It might have been more convenient and advantageous for myself had I continued my researches in peace and quiet. I do not try to proselytise, and it is really a matter of indifference to me, whether my contemporaries share or do not share my views. But the sight of a few brave men fighting the battle alone is by no means a matter of indifference to me. There is a certain cowardliness in believing their teachings, whilst allowing them to bear all the brunt of the fray for upholding opinions, which require so much courage to champion. To these brave spirits I dedicate my book.
