Descartes was an eighteenth-century mathematician and musician, He believed that all problems could be solved using mathematical logic. In this book which was published in 1701 after his death, he outlines the four main rules: (1) accept nothing as true that is not self-evident, (2) divide problems into their simplest parts, (3) solve problems by proceeding from simple to complex, and (4) recheck the reasoning.

The Cambridge Descartes Lexicon is the definitive reference source on René Descartes, 'the father of modern philosophy' and arguably among the most important philosophers of all time. Examining the full range of Descartes' achievements and legacy, it includes 256 in-depth entries that explain key concepts relating to his thought. Cumulatively they uncover interpretative disputes, trace his influences, and explain how his work was received by critics and developed by followers. There are entries on topics such as certainty, cogito ergo sum, doubt, dualism, free will, God, geometry, happiness, human being, knowledge, Meditations on First Philosophy, mind, passion, physics, and virtue, which are written by the largest and most distinguished team of Cartesian scholars ever assembled for a collaborative research project - 92 contributors from ten countries.

Change happens to us. It's measured in gains or losses: you find a spouse or lose a loved one; you receive a promotion or lose a job. Change happens around us. It's marked by natural and social factors: a good harvest, a natural disaster; an economic boom, a stock market plunge. Change is initiated by us. It's weighed by its outcome: you make a decision that improves your life; you make a choice that shatters your dreams. Transitional tides-whether personal or cultural-can bring on stress, confusion, and even panic. Only a small percentage of people respond to change in truly effective ways. Yet how we deal with change determines whether it will ultimately be a positive or negative force in our lives. Best-selling author Dr. Myles Munroe explains how we can tap into the positive power of change-no matter what the source of that change-enabling us to thrive while fulfilling our God-given purposes in life.

Descartes submitted his manuscript to many philosophers, theologians and a logician before publishing the Meditations. Their objections and his replies (many of which are quite extensive) were included in the first publication of the Meditations.
