Context

“Vain people, on the other hand, are fools and ignorant of themselves, and that manifestly; for, not being worthy of them, they attempt honourable undertakings, and then are found out; and tetadorn themselves with clothing and outward show and such things, and wish their strokes of good fortune to be made public, and speak about them as if they would be honoured for them. But undue humility is more opposed to pride than vanity is; for it is both commoner and worse. Pride, then, is concerned with honour on the grand scale, as has been said.
4
There seems to be in the sphere of honour also, as was said in our first remarks on the subject, a virtue which would appear to be related to pride as liberality is to magnificence.” source
