Dr. Widtsoe's pen has long been active in the cause of truth all truth. His scientific papers are numerous. His articles and books crusading for better irrigation and dry-farming practice have been translated into many languages. His Church books, courses of study, and compilations go back to his early young manhood. Books and manuals written by him and published number more than a score and a half, in addition to magazine and newspaper articles, pamphlets, tracts, and encyclopedic and other writings.
As a research scholar schooled in the finest institutions of two continents, as a former president first of a state agricultural college and then of a state university, as a consulting chemist, as director of an agricultural experiment station, as a member of government commissions and of scientific societies, as a churchman of many assignments, and as a world traveler, he has the stimulating manner of a true teacher, the open mind of a true scholar, the engaging charm of a true gentleman, and the true humility of a man of God. His pen, sparing in its use of words and direct in its approach, is nevertheless colorful in expression -- and it quickly focuses attention on fact, avoiding unsupportable generalization.
With this brief glimpse of a man and his work, neither of which needs introduction, it is gratifying to bring this volume to the readers who have asked for it and to the many students, both of science and religion, who will find in it many "aids to faith in a modern day."
