  We have already discussed Kant’s view of the mind’s handling of space and time, so we can proceed directly to his doctrine of synthesis. As Kant put it in one of his most famous passages, “Concepts without intuitions are empty, intuitions without concepts are blind” (A51=B75). Experience requires both percepts and concepts. As we might say now, to discriminate, we need information; but for information to be of any use to us, we must organize the information. This organization is provided by acts of synthesis.
