Descartes's so-called dualism is often taken to represent a fundamental revolution in ideas and the starting point of modern philosophy. ...but in substance his work is... better understood as an attempt to conserve the old truths in the face of new threats. His dualism was in essence an armistice... between the established religion and the emerging science of his time. ...isolating the mind from the physical world... ensured that many of the central doctrines of orthodoxy-immortality of the soul, the freedom of will, and, in general, the "special" status of humankind-were rendered immune to any possible contravention by the scientific investigation of the physical world. ... For men such as Descartes, Malebranche, and Leibniz, solving the mind-body problem was vital to preserving the theological and political order inherited from the Middle Ages... For Spinoza, it was a means of destroying that same order and discovering a new foundation for human worth.

The physicist needs a facility in looking at problems from several points of view. The exact analysis of real physical problems is usually quite complicated, and any particular physical situation may be too complicated to analyze directly by solving the differential equation. But one can still get a very good idea of the behavior of a system if one has some feel for the character of the solution in different circumstances. Ideas such as the field lines, capacitance, resistance, and inductance are, for such purposes, very useful. ... On the other hand, none of the heuristic models, such as field lines, is really adequate and accurate for all situations. There is only one precise way of presenting the laws, and that is by means of differential equations. They have the advantage of being fundamental and, so far as we know, precise. If you have learned the differential equations you can always go back to them. There is nothing to unlearn.

We are... bound to attach the greatest importance to the preliminary step taken by Lavoisier, who is even more justly called the father of modern chemistry than Kepler is called the father of modern astronomy. The exact claims of Lavoisier to this important place in the history of chemistry have been variously stated: ...since his time, and greatly through his labours, the quantitative method has been established as the ultimate test of chemical facts; the principle of this method being the rule that in all changes of combination and reaction, the total weight of the various ingredients-be they elementary bodies or compounds-remains unchanged. The science of chemistry was thus established upon an exact, a mathematical basis. By means of this method Lavoisier, utilising and analysing the results gained by himself and others before him, notably those of Priestley, Cavendish, and Black, succeeded in destroying the older theory of combustion, the so-called phlogistic theory.

The Soviet Union does not allow any church of any kind to interfere with education, and religion is not taught in public schools. It seems to me that this is the greatest gift of the Russian Revolution to the modern world. Most educated modern men no longer believe in religious dogma. If questioned they will usually resort to double-talk before admitting the fact. But who today actually believes that this world is ruled and directed by a benevolent person of great power who, on humble appeal, will change the course of events at our request? Who believes in miracles? Many folk follow religious ceremonies and services and allow their children to learn fairy tales and so-called religious truth, which in time the children come to recognize as conventional lies told by their parents and teachers for the children's good. One can hardly exaggerate the moral disaster of the custom. We have to thank the Soviet Union for the courage to stop it.

For, strange as the statement will appear at first sight, modern metaphysics, and to a large extent modern physical science, have been groping for centuries blindly after knowledge which occult philosophy has enjoyed in full measure all the while. Owing to a train of fortunate circumstances, I have come to know that this is the case; I have come into some contact with persons who are heirs of a greater knowledge concerning the mysteries of Nature and humanity than modern culture has yet evolved; and my present wish is to sketch the outlines of this knowledge, to record with exactitude the experimental proofs I have obtained that occult science invest its adepts with a control of natural forces superior to that enjoyed by physicists of the ordinary type, and the grounds there are for bestowing the most respectful consideration on the theories entertained by occult science concerning the constitution and destinies of the human soul.

I cannot believe that in the twentieth century the British people are by their deliberate vote going to constitute this assembly – a fraction of whom no doubt are men of real eminence and dignity, but the great majority of whom are quite ordinary people of the well-to-do class with all the narrowest prejudices and special interests of that class – I cannot believe that you by your votes are going to constitute them the main foundation on which the governing power in our land is reposed. I cannot believe the middle classes and the working classes, who after all have only to use their voting strength to get their own way, are going to degrade and cast away their own voting powers which their fathers won for them in the past...I cannot believe that the electors are going obsequiously to hand over their most vital constitutional right, namely, to choose the Chamber that governs the Government, to an antiquated body of titled persons utterly beyond their control.
