For more than sixty years, Deligny has built a body of work around children on the fringes. A work that inextricably links theory and practice, opportunities and attempts, writing and cinema. By a thought of both the immutable and the circumstantial; by a look that turns out – in an unusual sense – to be deeply and differently political.

In hegelian french-speaking litterature, only partial studies about Iena's period are available. The present book attempts to consider the whole of hegelian thinking of this time, and to question its transformations, as well in the field of logic as in those of philosophy of nature or philosophy of spirit.
