"While Fichte's middle Berlin period is one of the more important and productive sets of years in his career, there is no other book in English that provides as comprehensive and meticulous an account of the period as Matthew Nini does here. This project certainly will motivate further scholarship on this time in Fichte's career." - C. Jeffery Kinlaw, McMurry University and University of North Carolina at Pembroke"In this brilliant work of scholarly reconstruction, which is sure to become a critical touchstone, Nine's clear prose and lucid explanation of Fichte's Berlin lectures on the science of knowing will spark renewed interest in Fichte. His well-researched annotations also furnish fascinating glimpses into Fichte's battles with Schiller, Jacobi, and Schelling. Essential." - Choice
