d heat in argument are the surest proofs of folly
Obstinate in growing worse
Occasion to La Boetie to write his "Voluntary Servitude"
Occasions of the least lustre are ever the most dangerous
Occupy our thoughts about the general, and about universal cause
Of the fleeting years each steals something from me
Office of magnanimity openly and professedly to love and hate
Oftentimes agitated with divers passions
Old age: applaud the past and condemn the present
Old men who retain the memory of things past
Omit, as incredible, such things as they do not understand

Our extremest pleasure has some sort of groaning
Our fancy does what it will, both with itself and us
Our judgments are yet sick
Our justice presents to us but one hand
Our knowledge, which is a wretched foundation
Our qualities have no title but in comparison
Our will is more obstinate by being opposed
Over-circumspect and wary prudence is a mortal enemy
Overvalue things, because they are foreign, absent
Owe ourselves chiefly a
