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
     On all occasions to contradict and oppose
     One door into life, but a hundred thousand ways out
     One may be humble out of pride
     One may more boldly dare what nobody thinks you dare
     One may regret better times, but cannot fly from the present
     One must first know what is his own and what is not
     Only desire to become more wise, not more learned or eloquent
     Only secure harbour from the storms and tempests of life
     Only set the humours they would purge more violently in work
     Open speaking draws out discoveries, like wine and love
     Opinions they have of things and not by the things themselves
     Opinions we have are taken on authority and trust
     Opposition and contradiction entertain and nourish them
     Option now of continuing in life or of completing the voyage
     Order a purge for your brain, it will there be much better
     Order it so that your virtue may conquer your misfortune
     Ordinances it (Medicine)foists upon us
     Ordinary friendships, you are to walk with bridle in your hand
     Ordinary method of cure is carried on at the expense of life
     Others adore all of their own side
     Ought not only to have his hands, but his eyes, too, chaste
     Ought not to expect much either from his vigilance or power
     Ought to withdraw and retire his soul from the crowd
     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 and mostly to ourselves
     Passion has a more absolute command over us than reason
     Passion has already confounded his judgment
     Passion of dandling and caressing infants scarcely born
     Pay very strict usury who did not in due time pay the principal
     People are willing to be gulled in what they desire
     People conceiving they have right and title to be judges
     Perfect friendship I speak of is indivisible
     Perfect men as they are, they are yet simply men
     Perfection:  but I will not buy it so dear as it costs
