19.  Conclusion.

Having thus given an account of the original, sorts, and extent of our ideas, with several other considerations about these (I know not whether I may say) instruments, or materials of our knowledge, the method I at first proposed to myself would now require that I should immediately proceed to show, what use the understanding makes of them, and what knowledge we have by them.  This was that which, in the first general view I had of this subject, was all that I thought I should have to do:  but, upon a nearer approach, I find that there is so close a connexion between ideas and words, and our abstract ideas and general words have so constant a relation one to another, that it is impossible to speak clearly and distinctly of our knowledge, which all consists in propositions, without considering, first, the nature, use, and signification of Language; which, therefore, must be the business of the next Book.
