Albert EinsteinThe devil has put a penalty on all things we enjoy in life. Either we suffer in our health, or we suffer in our soul, or we get fat.
Albert EinsteinI am not a positivist. Positivism states that what cannot be observed does not exist.

One would have to say 'only what we observe exists,' which is obviously false.
