To some extent Berkeley removed this radical inconsistency, but in his philosophical work it may be said with safety there are two distinct aspects, and while it holds of Locke on the one hand, it stretches forward to Kantianism on the other.
It effected a revolution in his mode of thinking; so completely did the Kantian doctrine of the inherent moral worth of man harmonize with his own character, that his life becomes one effort to perfect a true philosophy, and to make its principles practical maxims. At first he seems to have thought that the best method for accomplishing his object would be to expound Kantianism in a popular, intelligible form.
This doctrine is derived from Berkeley and Hume on the one hand and from Kantianism on the other, and embodies the principle that nothing can exist for the mind save itself.
The remarks made above would not apply to the coherent system of idealism which may be evolved from Kant's writings, and which many would consider alone to deserve the name of Kantianism or Criticism.
