jects about which our senses have been conversant; whereof having settled ideas in our minds, we can revive, repeat, and add them one to another as often as we will, and consider the space or distance so imagined either as filled with solid parts, so that another body cannot come there without displacing and thrusting out the body that was there before, or else as void of solidity, so that a body of equal dimensions to that empty or pure space may be placed in it without the removing or expulsion of any thing that was there.

But in this every one has liberty: I propose it only for the more clear and distinct way of speaking.
Men differ little in clear simple ideas.§ 28. The knowing precisely what our words stand for, would, I imagine, in this as well as a great many other cases, quickly end the dispute: for I am apt to think that men, when they come to examine them, find their simple ideas all generally to agree, though in discourse with one another they perhaps confound one another with different names.
