Nothing invigorates and exalts the mind equally with pride and vanity; though at the same time love or tenderness is rather found to weaken and infeeble it. The same difference is observable betwixt the uneasy passions. Anger and hatred bestow a new force on all our thoughts and actions; while humility and shame deject and discourage us. Of these qualities of the passions, it will be necessary to form a distinct idea. Let us remember, that pride and hatred invigorate the soul; and love and humility infeeble it.
