Text combines scienc£o and fancy in speculation about p!urality of inhabited
worlds. Author hypothesizes that there are worlds without end of every con-
ceivable description in the universe; they are inhabited by intelligent beings
whose forms, organs, and number of senses are infinitely diverse as result of
physicai conditions peculiar to their particular worlds.

This life would be similar to man in many respects: a supporting structure,
a liquid nutrient system, a nervous system, a large brain. Two sexes seem
likely; beings would be land dwelling. Symmetry and coordination dictate pro-
bability of two arms each with multiple fingers, but there may be four legs in-
stead of two. H man were eradicated, it is likely that intelligent life would have
to evol.ve all over again since present animals have pas~eri the point of
differentiation.

In astronomy, the author says, we are facecl by contradictions. Not all the ap-
parent data of the moment can be correct; we do not know which fragments are
right and which are wrong. Because we cannot experiment with the universe,
we live in a kind of shifting uncertainty, shifting because as the years pass the
balance of certainty of a given piece of data changes.
