Understanding Time as the Form of Inner Sense



Abstract representation of time as an internal processing rhythm

Having established Space as the pure form of outer sense, Kant now turns inward. How do we experience our own thoughts, feelings, and the succession of events?

KEY DEFINITIONS FROM §4:

Term Plain English Kant’s Core Definition
Time
(Die Zeit)		 The processing clock of the mind. The necessary condition for experiencing “before,” “after,” or “at the same time.” An a priori intuition lying at the basis of all succession and simultaneity.
Inner Sense
(Innere Sinn)		 The mind’s capacity to observe its own internal states (thoughts, feelings). The property of our mind by which we intuit ourselves and our inner state.

The Mathematical Structure of Inner Experience

\$\$ \text{Inner Experience} \quad = \quad \underbrace{\quad \text{Time} \quad}_{\textit{a priori} \text{ Clock}} \quad \times \quad \underbrace{\quad \text{Internal States} \quad}_{\textit{a posteriori} \text{ feelings/thoughts}} \$\$

Time is not an empirical concept that has been derived from any experience… Only on the presupposition of time can we represent to ourselves a number of things as existing simultaneously or successively.
