The Lee-Yang Circle Theorem

Question

Slosson describes his discovery of pragmatism as realizing he had been a pragmatist "all his life without knowing it." How would you explain pragmatism as Slosson seems to understand it, using his experiences in journalism and chemistry to illustrate its core principles to someone entirely unfamiliar with the philosophy?

Synthesized answer

Slosson understood pragmatism as a way of thinking where actions and truths are valued based on their consequences and practicality, rather than their causes or precedent [1]. He believed that to determine if something is true, one must try it and observe how it works [2]. If it consistently works well for many people, it possesses some truth. Conversely, if it leads to wrong outcomes, it is false, at least in part [2]. If a concept cannot be tested, it has no meaning and makes no difference if believed or not [2].

His background in journalism and chemistry informed this view. In science, this "pragmatic mode of thinking is universal and unquestioned" [1]. This led him to naturally apply the same approach to other areas like politics and ethics, evaluating them by their results [1]. He saw thought as a tool, a means to an end, essential for action and for understanding the world's meaning to oneself [4]. The need for thought arises when asking "Why?" or "Which?" to achieve an objective [4].

From the book

journalist through the study of chemistry, and in science the pragmatic mode of thinking is universal and unquestioned. So when I went to writing about other things,—politics, law, ethics, history, religion, and the like,—I naturally used my brains in the same way as in science, that is, I persisted in the valuation of all acts by their consequences instead of their causes and in the validation of all truths by practicality instead of precedent. But when I found how this way of thinking shocked, annoyed, or amused people I began to fear that I should have to drop it as I had other evidences…

by a Chinaman. Even Herbert Spencer once condescended to translate his famous definition of evolution into Anglo-Saxon. Since I am obliged to use the word "pragmatism" more than once in this book I may forestall criticism by putting here my ​ Monosyllabic Definition of Pragmatism The one way to find out if a thing is true is to try it and see how it works. If it works well for a long time and for all folks, it must have some truth in it. If it works wrong it is false, at least in part. If there is no way to test it, then it has no sense. It means naught to us when we cannot tell what odds it…

n a way that we make truth for our own use. What we think must be of use to us in some way, else why should we think it? The truth is what is good for us, what helps us, what gives us joy and strength, what shows us how to act, what ties up fact to fact, so the chain will hold, what makes us see all things clear and straight, and what keeps us from stray paths that turn out wrong in the end. Thought is a tool, a means to an end. Man has to act, and so he must think. In this way he asks the world what it means to him. The need for thought first comes when man asks "Why?" or "Which?" so that he…

Poincaré I unearthed in a Paris flat, James I heard in a Columbia lecture room; Ostwald I found in a Saxon village; Schiller I caught in an Oxford quad. I was thinking of going to China to see Wang Yang-ming , but fortunately before I had bought my steamer ticket or learned Chinese I discovered that he had been dead for three centuries. Some who have read or tried to read what I said about Bergson and Poincaré have complained that I used too many big words, and one man…
