Russell's Hypothesis

There is no logical impossibility to suppose

that all of life is a dream,

in which we ourselves

create all that comes before us.

But although this is not logically impossible,

there is no reason whatever to suppose that it is true;

and it is, in fact, a less simple hypothesis,

viewed as a means of accounting for the facts of our own life,

than the common-sense hypothesis

 that there really are objects, and living beings,

 independent of us,

whose action causes our sensations.
