German idealism first introduced the creativity of thought into philosophy

Evidence

Until classical German philosophy, philosophy was conceived as a receptive, or at the most an ordering activity, i.e. as knowledge of a mechanism that functioned objectively outside man. Classical German philosophy introduced the concept of “creativity” of thought, but in an idealistic and speculative sense. — Antonio Gramsci, Selections from the Prison Notebooks, 1242
