Read it through once

What follows from the admission? It establishes no new truth, it gives us no additional insight into our hidden nature, neither its action nor itself. Philosophy, impatient as it may be to build, has much work yet remaining, as pioneer for the overgrowth of ages. It makes one step towards this object; it destroys error, and the roots of error. It leaves, what it is too often the duty of the reformer in political and ethical questions to leave, a vacancy. It reduces the mind to that freedom in which it would have acted, but for the misuse of words and signs, the instruments of its own creation. By signs, I would be understood in a wide sense, including what is properly meant by that term, and what I peculiarly mean. In this latter sense, almost all familiar objects are signs, standing, not for themselves, but for others, in their capacity of suggesting one thought which shall lead to a train of thoughts. Our whole life is thus an education of error.
