Chemistry is the science which treats of the intra-atomic or the intra-molecular changes which material things undergo under various influences. Mental is defined as "of or appertaining to the mind, including intellect, feeling, and will, or the entire rational nature." Science is knowledge gained and verified by exact observation and correct thinking. Mental chemistry is, therefore, the science which treats of the changes which material conditions undergo through the operations of the mind, verified by exact observation and correct thinking. - From "Mental Chemistry" ----THERE is, and always has been, a widespread belief in Fate, or Destiny, that is, in an eternal and inscrutable Power which apportions definite ends to both individuals and nations. This belief has arisen from long observation of the facts of life. Men are conscious that there are certain occurrences which they cannot control, and are powerless to avert. Birth and death, for instance, are inevitable, and many of the incidents of life appear equally inevitable. - From "The Mastery of Destiny" ---- Enjoy these classic works of New Thought from two of its most famous writers.
