Jacobi It is true that Fourier had the opinion that the principal object of mathematics was public use and the explanation of natural phenomena; but a philosopher like him ought to know that the sole object of the science is the honor of the human spirit and that under this view a problem of numbers is worth as much as a problem on the system of the world.

Fourier 确实有过这样的看法，认为数学的主要目的是公众的需要和对自然现象的解释；但是像他这样一个哲学家应当知道，科学的唯一目的是人类精神的光荣，而且应当知道，在这种观点之下，数〔论〕的问题和关于世界体系的问题具有同等价值。
