The "figurative system of human knowledge", sometimes known as the tree of Diderot and d'Alembert, was a tree developed to represent the structure of knowledge itself, produced for the Encyclopédie by Jean le Rond d'Alembert and Denis Diderot.

The tree was a taxonomy of human knowledge, inspired by Francis Bacon's Advancement of Knowledge. The three main branches of knowledge in the tree are: "Memory"/History, "Reason"/Philosophy, and "Imagination"/Poetry.

Notable is the fact that theology is ordered under 'Philosophy'. The historian Robert Darnton has argued that this categorization of religion as being subject to human reason, and not a source of knowledge in and of itself (revelation), was a significant factor in the controversy surrounding the work. Additionally notice that 'Knowledge of God' is only a few nodes away from 'Divination' and 'Black Magic'.

The original version, in French, can be seen in the graphic on the right. Below is a version of it rendered in English as a bulleted outline.
