We are not satisfied to be right, unless we can prove others to be quite wrong. - William Hazlitt

We never do anything well till we cease to think about the manner of doing it.

We all wear some disguise — make some professions — use some artifice to set ourselves off as being better than we are; and yet it is not denied that we have some good intentions and praiseworthy qualities at bottom, though we may endeavour to keep some others that we think less to our credit as much as possible in the background…

The origin of all science is in the desire to know causes; and the origin of all false science and imposture is in the desire to accept false causes rather than none; or, which is the same thing, in the unwillingness to acknowledge our own ignorance.
