This is a textbook (or better, a workbook) in modern philosophy. It combines readings from primary sources with two pedagogical tools. Paragraphs in italics introduce figures and texts. Numbered study questions (also in italics) ask students to reconstruct an argument or position from the text, or draw connections among the readings. The introductory chapter, Minilogic and Glossary, are designed to present the basic tools of philosophy and sketch some principles and positions.
