The efforts of that verity, I need hardly say, display a very different sort of force after we have actually and attentively read those hundreds of extraordinary stories which, without appearing to do so, strike to the very roots of history. We soon lose all inclination to doubt. We penetrate into another world and come to a stop all out of countenance. We no longer know where we stand; before and after overlap and mingle. We no longer distinguish the insidious and factitious but indispensable line which separates the years that have gone by from the years that are to come. We clutch at the hours and days of the past and present to reassure ourselves, to fasten on to some certainty, to convince ourselves that we are still in our right place in this life where that which is not yet seems as substantial, as real, as positive, as powerful as that which is no more. We discover with uneasiness that time, on which we based our whole existence, itself no longer exists. It is no longer the swiftest of our gods, known to us only by its flight across all things: it alters its position no more than space, of which it is doubtless but the incomprehensible reflex. It reigns in the centre of every event; and every event is fixed in its centre; and all that comes and all that goes passes from end to end of our little life without moving by a hair's breadth around its motionless pivot. It is entitled to but one of the thousand names which we have been wont to lavish upon its power, a power that seemed to us manifold and innumerable: yesterday, recently, formerly, erewhile, after, before, tomorrow, soon, never, later fall like childish masks, whereas to-day and always completely cover with their united shadows the idea which we form in the end of a duration which has no subdivisions, no breaks and no stages, which is pulseless, motionless and boundless. 11 Many are the theories which men have imagined in their attempts to explain the working of the strange phenomenon; and many others might be imagined. As we have seen, self-suggestion and telepathy explain certain cases which concern events already in existence, but still latent and perceived before the knowledge of them can reach us by the normal process of the senses or the intelligence. But, even by extending these two theories to their uttermost point and positively abusing their accommodating elasticity, we do not succeed in illumining by their aid more than a rather restricted portion of the vast undiscovered land. We must therefore look for something else.
