Relations of Place and Extension.
The relation also that things have to one another in their PLACES and distances is very obvious to observe; as above, below, a mile distant from Charing-cross, in England, and in London.

But as in duration, so in extension and bulk, there are some ideas that are relative which we signify by names that are thought positive; as GREAT and LITTLE are truly relations.

For here also, having, by observation, settled in our minds the ideas of the bigness of several species of things from those we have been most accustomed to, we make them as it were the standards, whereby to denominate the bulk of others.

Thus we call a great apple, such a one as is bigger than the ordinary sort of those we have been used to; and a little horse, such a one as comes not up to the size of that idea which we have in our minds to belong ordinarily to horses; and that will be a great horse to a Welchman, which is but a little one to a Fleming; they two having, from the different breed of their countries, taken several-sized ideas to which they compare, and in relation to which they denominate their great and their little.

Absolute Terms often stand for Relations.
So likewise weak and strong are but relative denominations of power, compared to some ideas we have at that time of greater or less power.
Thus, when we say a weak man, we mean one that has not so much strength or power to move as usually men have, or usually those of his size have; which is a comparing his strength to the idea we have of the usual strength of men, or men of such a size.
