Some excel in rhyme who reason foolishly. [ Boileau ]

It is altogether vain to learn wisdom, and yet live foolishly. [ Proverb ]

A sick man acts foolishly for himself who makes his doctor his heir.

It is wiser to run away when there is no remedy, than to stay and die in the field foolishly. [ Proverb ]

The use we make of our fortune determines its sufficiency. A little is enough if used wisely, and too much if expended foolishly. [ Bovee ]

That which we foolishly call vastness is, rightly considered, not more wonderful, not more impressive, than that which we insolently call littleness; and the infinity of God is not mysterious, it is only unfathomable, not concealed, but incomprehensible: it is a clear infinity, the darkness of the pure, unsearchable sea. [ Ruskin ]

Living authors, therefore, are usually bad companions. If they have not gained character, they seek to do so by methods often ridiculous, always disgusting; and if they have established a character, they are silent for fear of losing by their tongue what they have acquired by their pen - for many authors converse much more foolishly than Goldsmith, who have never written half so well. [ Colton ]
