Sam started his journey of understanding the world as it is in the late 1970s when he first read Carl Sagan’s The Dragons of Eden: Speculations on the Evolution of Human Intelligence. He earned his Bachelors of English with a minor in History cum laude from the University of Maryland University College (now University of Maryland Global Campus) in 1992. Sam has spent the past 30+ years educating himself with countless science and other books written for the layman on subjects as diverse as cosmology, physics, biology, anthropology, psychology and philosophy. He saw a need for a book about the Tenets of Critical Thinking because of the volume of misinformation and disinformation, and now fake news and deep fakes that overwhelm us every day. Sam has been teaching adults and designing and writing instructional materials for 25+ years. Sam lives with his wife and two children in Jupiter, Florida.
