“A work in which there are theories is like an object which still has its price-tag on.”

“A work of art that contains theories is like an object on which the price tag has been left. ”

“We had all opted to take City's financial reporting course work, which, in theory, meant we wanted to write about stock prices and corporate takeovers. That, of course, was a joke. No one still in their twenties, and broke, goes into journalism to write about money—a subject in which they still have zero practical experience.”

“The price tag that you put on your soul will determine the people and circumstances in which you find yourself.”

“I saw that "success," "failure," "poverty", "riches," were price tags, money values of the market place which had mesmerized and sidetracked me for years.”

“All rational knowledge is either material, and concerns some objects, or formal, and is occupied only with the form of understanding and reason itself and with the universal rules of thinking, without regard to distinctions among objects. formal philosophy is called logic. Material philosophy, however, which has to do with definite object objects and the laws to which they are subject, is divided into two parts. This is because these laws are either laws of nature or laws of freedom. The science of the former is called physics, and that of the latter ethics. The former is also called theory of nature and the latter theory of morals.”
