There is no space in the spiritual world but there is extense there; extension in the spiritual world can no more be questioned than “no space” there, because this also is taught in the Writings.
In a field where there should be precision in terminology “existentialism” stands out as being unusually vague. Confusion arises from the use of the term in two different ways. Existentialism refers both to a philosophic movement, including a great number of the well known philosophers since Hegel, and to a particular philosophy developed by Jean Paul Sartre and his contemporaries as a particular part of the whole movement. Indeed, the term has been stretched to the point where some proponents of existentialism have linked everyone in the modern period to the trend, including even the pragmatists. They believe that the pragmatists —who have already had, and should continue to have, far greater effect than the existentialists—are merely existentialists unable to express themselves clearly.
