Bygone Beliefs: being a series of excursions in the byways of thought

THESE Excursions in the Byways of Thought were undertaken at different times and on different occasions; consequently, the reader may be able to detect in them inequalities of treatment. He may feel that I have lingered too long in some byways and hurried too rapidly through others, taking, as it were, but a general view of the road in the latter case, whilst examining everything that could be seen in the former with, perhaps, undue care. As a matter of fact, how ever, all these excursions have been undertaken with one and the same object in view, that, namely, of understanding aright and appreciating at their true worth some of the more curious byways along which human thought has travelled. It is easy for the superficial thinker to dismiss much of the thought of the past (and, indeed, of the present) as mere superstition, not worth the trouble of investigation: but it is not scientific. There is a reason for every belief, even the most fantastic, and it should be our object to discover this reason. How far, if at all, the reason in any case justifies us in holding a similar belief is, of course, another question
