Read it through once

To avoid, as much as possible, this embarrassment, I shall carefully distinguish that of which I have experience, from that of which I have not; and, in the former, I shall content myself with reporting accurately my own sensations. From such reports I hope to deduce certain general rules; and in the exposition of these rules I shall endeavour to be plain, not proud of subtilty; to display, rather than to create surprizes; and to seek only after the light of nature, not after the ornaments of philosophy.
