The exploration of the fourth dimension is helpful in the understanding of geomet-ric concepts of everyday use in modern physics. But it is also a valuable way of establish-ing analogies between 4D and the moves of ethical singularity in situation. This article travels through some of the different aspects of 4D, which takes us to the subjectively irrepresentable. From there, a complex analogy with the ethical act starts, and various points of contact between 4D and ethical act allow for a better comprehension of the latter.
Key words: fourth dimension – ethical act – tesseract – Charles Hinton
