Although Swedenborg wrote in Latin, his works have been translated into thirty-three spoken European and Asiatic languages. Since 1820, over five million copies of his theological works have been sold. His prose style is Ciceronian in its clarity. Although he is dealing with the most profound subjects, there is not the least trace of any ambiguity or confusion of thought.

Measured by the most severe tests of internal consistency, such as the criterion of coherence so dear to the heart of Rationalism, Swedenborg's consistency of statement, both over the whole time span of the twenty-seven years or by the more severe test of using deductions to test the degree of agreement or disagreement with other deductions is inerrable. His works are a completely unified system of thought, cohering not only internally but also agreeing both with Scripture and also with modern science.

His whole system is expressed in unimpassioned, cool, logical prose, since he repeatedly insisted that to evaluate and then to accept the truth of any proposition, an individual must exercise his God-given faculties of reason and of judgement. All he asks of any reader is unbiased rational appraisal.
