“Anything dead tends to remain within the three ordinary dimensions, while anything living constantly transcends them” (Rudolf Steiner).

The point, line, plane and solid objects represent the first three dimensions, but a kind of reversal of space is involved in the ascent to a fourth dimension. Steiner leads us to the brink of this new perspective—as nearly as it can be done with words, diagrams, analogies, and examples of many kinds. In doing so, he continues his life-long project of demonstrating that our objective, everyday thinking is the lowest rung of a ladder that reaches up to literally infinite heights.

The talks in this series and the selections from the question-and-answer sessions on many mathematical topics over the years are translated into English for the first time in The Fourth Dimension. They bring us to tantalizing new horizons of awareness where Steiner hoped to lead his listeners:

“Part of the charm of the fourth dimension is that it is a geometrical concept that interests popular culture as much as it does mathematicians. In both its popular and scientific applications, the fourth dimension has had both gnostic and agnostic exponents” (from the Introduction).
