Because the newer methods of treatment are good, it does not follow that the old ones were bad: for if our honorable and worshipful ancestors had not recovered from their ailments, you and I would not be here today.
I am not a positivist. Positivism states that what cannot be observed does not exist. This conception is scientifically indefensible, for it is impossible to make valid affirmations of what people 'can' or 'cannot' observe. One would have to say 'only what we observe exists,' which is obviously false.
I've tried to be totally present, so that when I'm finished with a piece of work, I'm finished. ... The work, once completed, does not need me. The work I'm working on needs my total concentration. The one that's finished doesn't belong to me anymore. It belongs to itself.
With wavering steps does fickle fortune stray,
Nowhere she finds a firm and fixed abode;
But now all smiles, and now again all frowns,
She's constant only in inconstancy.
I don’t regret for a single moment having lived for pleasure. I did it to the full, as one should do everything that one does. There was no pleasure I did not experience.
How does it happen, Maecenas, that no one is content with that lot in life which he has chosen, or which chance has thrown in his way, but praises those who follow a different course?
[Lat., Qui fit, Maecenas, ut nemo quam sibi sortem,
Seu ratio dederit, seu fors objecerit, illa
Contentus vivat? laudet diversa sequentes.]
