The Edinburgh Lectures on Mental Science contains the substance of a course of lectures recently given by the writer in the Queen Street Hall, Edinburgh. Its purpose is to indicate the Natural Principles governing the relation between Mental Action and Material Conditions, and thus to afford the student an intelligible starting-point for the practical study of the subject."The addresses contained in The Dore Lectures on Mental Science include a progressive development of thought through the dozen lectures which compose this volume. They all aim at expressing the same fundamental idea, though the laws of the universe can never be broken, they can be made to work under special conditions which will produce results that could not be produced under the conditions spontaneously provided by nature. This is a simple scientific principle and it shows us the place which is occupied by the personal factor, that of an intelligence which sees beyond the present limited manifestation of the Law into its real essence, and which thus constitutes the instrumentality by which the infinite possibilities of the Law can be evoked into forms of power, usefulness, and beauty.Thomas Troward was Her Majesty's Assistant Commissioner and later Divisional Judge of the North Indian Punjab from 1869 until his retirement in 1896. It is this later period for which he is best remembered and most celebrated; in it he was at last able to devote himself to his great interest in metaphysical and esoteric studies. Troward is one of the founding fathers of Mental Science and a leading proponent of the 'New Thought' movement, a forerunner of what is now known as 'New Age' thinking.
