Aaron Larsen, DA

Dr. Aaron Larsen currently teaches history, Latin, logic, and rhetoric at Regents School of Charlottesville in Virginia. He previously taught at two classical schools in Pennsylvania. In 2001, Dr. Larsen joined a team led by Dr. Christopher Perrin and two other colleagues to help form Classical Academic Press. The motivation behind this endeavor was to produce exceptional Latin and logic curricula for the classical education movement. The first results of this collaboration included the publication of their logic text, The Art of Argument, and the three-volume Latin for Children series. Aaron is also a coauthor of The Discovery of Deduction: An Introduction to Formal Logic.

Aaron received his BA in history, with minors in philosophy and education, from Covenant College in Georgia. He completed his coursework for his DA in modern world history from St. John’s University in New York and went on to write his doctoral thesis on the Meiji Restoration, which, as he likes to say, is “the most important event in world history that nobody’s ever heard of.”
