Wallis did not become interested in mathematics till the age of thirty-one, but devoted himself to the subject for the rest of his life. One of the earliest and most important books on algebra ever written in English was his treatise published in 1685. It contains a brief historical sketch of the subject which is unfortunately not entirely accurate, but his treatment of the theory and practice of arithmetic and algebra has made the book a standard work for reference ever since.

I am not writing for those who do not believe that there is such a thing as clairvoyance, nor am I seeking to convince those who are in doubt about the matter... I am addressing myself to the better-instructed class who know that clairvoyance exists, and are sufficiently interested in the subject to be glad of information as to its methods and possibilities; and I would assure them that what I write is the result of much careful study and experiment.

My purpose in writing these essays has been to acquaint men who are interested in the bearings of modern history on public life with sundry statesmen whose time was devoted not to seeking office or to winning a brief popular fame by chicanery or pettifoggery, but to serving the great interests of modern states and, indeed, of universal humanity. I would present these statesmen and their work as especially worthy to be studied by those who aspire to serve their country in any way.

Without a doubt, the Theologico-Politicus Theological-Political Treatise is one of the most important and influential books in the history of philosophy, in religious and political thought, and even in Bible studies. More than any other work, it laid the foundation for modern critical and historical approaches to the Bible. And while often overlooked in books on the history of political thought, the Treatise also has a proud and well-deserved place in the rise of democratic theory, civil liberties, and politcal liberalism.

We shall see that the mathematical treatment of the subject [of electricity] has been greatly developed by writers who express themselves in terms of the 'Two Fluids' theory. Their results, however, have been deduced entirely from data which can be proved by experiment, and which must therefore be true, whether we adopt the theory of two fluids or not. The experimental verification of the mathematical results therefore is no evidence for or against the peculiar doctrines of this theory.

Here and there it happened in my practice that a patient grew beyond himself because of unknown potentialities, and this became an experience of prime importance to me. I had learned in the meanwhile that the greatest and most important problems of life are all in a certain sense insoluble. They must be so because they express the necessary polarity inherent in every self-regulating system. They can never be solved, but only outgrown.
