A prolific and versatile writer, he wrote more than five hundred books, pamphlets and journals on various topics (including politics, crime, religion, marriage, psychology and supernatural). He was also a pioneer of economic journalism. Second Thoughts are Best is Defoe's philosophical work on various subjects.
