Originally published in 1925, this book contains three lectures delivered by the British theologian F. R. Tennant (1866–1957) at the University of London during 1924. The three lectures, all of which relate to the nature of miracles, are titled as follows: 'Miracle and the Reign of Law', Natural and Supernatural Causation', and 'Credibility and Alleged Actuality of Miracle'. Notes are included at the end of the text. This book will be of value to anyone with an interest in the works of Tennant and theology.
