'This book's title perfectly captures its content … This is certainly a niche work and will largely interest historical specialists. But the scholarship is solid and will give readers a vivid sense of the lively debates on practical philosophy that informed and reacted to the better-known works of Kant and Hegel … Recommended.' S. E. Forschler, Choice
'The conceptual richness, the fruitfulness of the themes addressed, just like the attention paid to underage authors, constitute the main merits of this collection, which allows to take little-explored paths within German classical philosophy.' Sabina Tortorella, Archives de philosophie (translated from French)
