The ‘Conclusion’ reviews the mission of John Locke's philosophy. For Locke, the task of a philosopher was to prove that the truth was independent of human desires and tastes, and that at least part of it lay within the reach of human understanding. He understood the bearing that this had on the way that men live. His conviction that truth could be found and was worth seeking inspired the way he lived, and is an example of intellectual courage. Although such a belief is harder to defend today, some still live as though it were true.
