A New Era of Thought

This non-fiction work was written in the 19th century by Charles Howard Hinton. The philosophical theme of the book focuses on exploring the fourth dimension and its implications on human thinking. The first part is a collection of philosophical and mathematical essays on the fourth dimension, while in the second part Hinton develops a system of colored cubes. These cubes serve as models to get a four-dimensional perception as a basis of four-dimensional thinking.
