In time each instant is, only in so far as it has effaced the preceding one, its generator, to be itself in turn as quickly effaced. The past and the future (considered apart from the consequences of their content) are empty as a dream, and the present is only the indivisible and unenduring boundary between them. The substance of this doctrine is old: it appears in Heraclitus when he laments the eternal flux of things; in Plato when he degrades the object to that which is ever becoming, but never being; in Spinoza as the doctrine of the mere accidents of the one substance which is and endures. Kant opposes what is thus known as the mere phenomenon to the thing in itself. Lastly, the ancient wisdom of the Indian philosophers declares:
It is Mâyâ, the veil of deception, which blinds the eyes of mortals, and makes them behold a world of which they cannot say either that it is or that it is not: for it is like a dream; it is like the sunshine on the sand which the traveller takes from afar for water, or the stray piece of rope he mistakes for a snake.
These similes are repeated in innumerable passages of the Vedas and the Puranas. But what all these mean, and that of which they all speak, is nothing more than what we have just considered.
Artur Schopenhauer – The World As Idea. First Aspect
Thought experiment: the brain is closed in the dish and stimulated by an apparatus connected to receive stimuli. This apparatus (or scientist through it) creates a perfectly coherent illusion of the existence of persons, objects of everyday experience (however, all experiences are actually the result of electrical impulses sent by the computer). You can go ahead and assume that all people (all sensory organisms) are the brains (nervous systems) in the vessels connected to the system that generates a collective hallucination.
The age of volatile belief is intimately linked with the impact of the technetronic revolution on existing ideologies and outlooks on life. What man thinks is closely related to what man experiences. The relationship between the two is not causal but interacting: experience affects thought, and thought conditions the interpretation of experience.
Today the dominant pattern seems increasingly to be that of highly individualistic, unstructured, changing perspectives. Institutionalized beliefs, the result of the merger of ideas and institutions, no longer appear to many as vital and relevant, while the skepticism that has contributed so heavily to the undermining of institutionalized beliefs now clashes with the new emphasis on passion and involvement. The result for many is an era of fads, of rapidly shifting beliefs, with emotions providing for some the unifying cement previously supplied by institutions and with the faded revolutionary slogans of the past providing the needed inspiration for facing an altogether different future.
