This chapter introduces a constellation of thinkers who had a major influence on Fichte: Kant, Reinhold, and Maimon. It begins with Kant’s effort to defend the coexistence of freedom and causal mechanism, leading up to his thesis that a free will and a will under moral laws are ‘reciprocal concepts.’ Reinhold criticizes this thesis on the grounds that it renders free yet immoral action impossible, and he proposes a new definition of freedom as our capacity to choose between our ‘selfish drive’ and our ‘unselfish drive.’ However, as Maimon observes, this new definition gives rise to the question of what, if anything, determines the agent to act one way or the other. The solution Fichte proposes in §10 of the System of Ethics comes in the form of his Genetic Model of freedom: the idea that indeterminacy and determinacy of choice are but stages in the emergence of freedom.
