KANTIAN ACTIVE SYNTHESIS AS THE BASIS OF HUMAN KNOWLEDGE
1. Introduction
Knowledge in Kant‟s critical philosophy cannot be explained as the passive reception
of impressions because experience becomes intelligible only when sensory material
is organised by the mind (University of South Africa, 2010:3). The central idea of
active synthesis therefore concerns the way receptivity and spontaneity work
together, rather than the replacement of experience by pure thought. Human
sensibility supplies a manifold of intuition, while the understanding actively combines
and orders that manifold through concepts and rules, which gives cognition a unified
and objective form (Land, 2006:189–220). This position was developed to overcome
the opposing weaknesses of rationalism and empiricism while also explaining how
necessary and universal knowledge can relate to objects of experience. The

discussion below explains the main stages of this synthesis, including space and
time, imagination, categories and transcendental apperception, before evaluating its
strengths and difficulties. The argument defended is that active synthesis gives a
powerful account of the conditions under which experience can count as knowledge,
although the scope of conceptual activity and the status of Kant‟s fixed a priori
framework remain disputed (Kant, 1998:A50/B74–A51/B75).
2. The epistemological problem behind active synthesis
2.1 Rationalism, empiricism and the need for synthesis
The need for synthesis arises from the limits Kant identified in both rationalism and
empiricism, because neither approach could independently explain the full structure
of human knowledge (University of South Africa, 2010:3). Rationalism gives priority
to concepts and reason, but without sensory content it struggles to explain how
thought reaches actual objects in the world. Empiricism begins from impressions and
therefore respects the role of experience, yet it has difficulty explaining necessity,
objectivity and the lawful unity through which different perceptions are understood as
one experience (Ginsborg, 2006:59–106). The critical alternative does not simply
place the two schools side by side. It claims that cognition requires two distinct but
cooperating powers, since objects must be given through sensibility and thought
through the understanding. Active synthesis is therefore a structural relation between
