If space and time are necessary for experience, then these ideas of space and time cannot be derived from experience. Our knowledge that objects must have been experienced in space and time is synthetic a priori knowledge.
Synthetic a priori knowledge: Knowledge that can be known independantly of experience but it is nevertheless not analytically true. 'Every event has a cause' (Hume does not accept that synthetic a priori knowledge is possible (hume's fork))
Suppose the mind had 3 characteristic powers:
1: Sensibility - The mind has the power to be receptive to particular objects and events in experience (which he calls intuitions)
