These essays on debatable subjects have been written at different times - some of them under stress of strong feeling - and they deal with problems of permanent interest. A few have appeared in serial or other form and in their case thanks are due for permission to reprint. Lectures and Addresses on educational, psychical, and ordinary scientific subjects have been excluded, but may possibly appear in future volumes.
Sir Oliver Joseph Lodge, FRS was a physicist and writer involved in the development of key patents in wireless telegraphy. Lodge, in his Royal Institution lectures ("The Work of Hertz and Some of His Successors"), coined the term "coherer." He gained the "syntonic" (or tuning) patent from the United States Patent Office in 1898.
In many ways, Sir Oliver Lodge could have been writing these essays in this century. He challenges readers to think beyond materialism in science; encourage the role of women in political office; the need for universal arbitration rather than war; moral and ethical dilemmas in pursuit of wealth, and in using the work of many to benefit a few. Income inequality in wealthy nations is creating a great divide among citizens and contributing to social unrest in many ways - witness aspects of the recent moves of Brexit and the election in the United States, and the rise of populism. He encourages cooperation vs. the destruction of competition. This volume is well worth revisiting and versions of it are widely available on line as ebooks.
