Kant claims that there are 2 different styles of judgements, which happen to be polarities. There are judgments caused by one's perception and judgments caused by one's experience. Judgments from perception are simple impressions usually brought on by the senses and are synthetic a posteriori. Hume feels these certain judgments act as the centerpiece of one's knowledge as they do not do any further investigative research. This would mean that a perceptive judgment is noncontroversial to the empiricist while judgments brought on through experience are controversial. Kant states that judgments through experience is the separation of sensory information into categories, which also is synthetic a priori.
