bject matter from the point of view of Science Fiction,
the style of writing was almost always on the highest level.

Then we realized that this magazine was no menace to the
literature of Science Fiction, but a valuable addition. It
could afford the better writers and hence keep up the
quality of work of every writer. It was adopting as its own
a type of Science Fiction that the rest minimized, and that
demanded good writing--a type having a skeleton of science,
like the girders of a great building, holding it erect and
determining its shape, yet holding the skeleton of less
importance than the vision of the completed edifice. Stories
with emphasis on the fiction rather than the science.

But enough of that. Here is a hopeful thought for the
time-travelers. There is nothing in physics or chemistry to
prevent you from going into the past or future--at least,
the future--and shaking hands with yourself or killing
yourself. We will eliminate the past, for it seems that it
cannot be altered physically. But take the future: not so
very far from to-day the matter of your body will have been
totally replaced by new matter; the old will disappear in
waste. Physically, you will be a new man, and physically the
matter of to-day may destroy that of to-morrow and return in
itself unaltered. But none-the-less there will be some
limiting interval during which "you" have not been entirely
transformed to new matter, so that an atom would have to be
in two places at once.

Maybe time-traveling progresses in little jumps like
emission of light. And maybe an atom can be in two places at
once. If you are going to treat time as just another
dimension, there seems to be no reason why an object which
can be in one place at two times cannot be at one time in
two places. This is all physics. The paradoxes of
time-traveling arise more particularly from its effect on
what we call consciousness, the something that makes me
"me"--an individual. We can imagine an atom in two places at
once, but not a soul, if you will. This will not bother the
materialist who considers a living creature merely a
machine, but it will most of us. So I must be content with
offering a materialistic possibility of traveling in time.
