Do you know where in the Meditations this quote arises? I tried searching for "worth" in a couple online versions, but all I found was from the end of Book Seven here:

What object soever, our reasonable and sociable faculty doth meet with, that affords nothing either for the satisfaction of reason, or for the practice of charity, she worthily doth think unworthy of herself.

...which, in this version, reads:

Whatever the rational and political (social) faculty finds to be neither intelligent nor social, it properly judges to be inferior to itself.
