 However, when deductions are “complex and involved” (AT 10: 408, CSM 1: 37) and “we infer a proposition from many disconnected propositions”, then “our intellectual capacity is often insufficient to enable us to encompass them all in a single intuition” (AT 10: 389, CSM 1: 26). Fortunately, the scope of intuition can be expanded by means of an operation Descartes terms “enumeration”.
