Locke-Chapter I- Introduction

I think this pertains to Method- Locke explains how we as people know what we are capable of doing. In paragraph 6 he says and when we have well surveyed the powers of our own mind, and made some estimate what we may expect from them, we shall not be inclined either to sit still....I think he is saying if you know your capabilities and the use of your, go to the extent in using it since you have those capabilities.
