“Where is the boundary for the single individual in his concrete existence between what is lack of will and what is lack of ability; what is indolence and earthly selfishness and what is the limitation of finitude?”

Drawn and Quartered (1983)

The Inferno (1917), Ch. XIV
Context: Where are the words that will light the way? What is humanity in the world, and what is the world?
Everything is within me, and there are no judges, and there are no boundaries and no limits to me. The de profundis, the effort not to die, the fall of desire with its soaring cry, all this has not stopped. It is part of the immense liberty which the incessant mechanism of the human heart exercises (always something different, always!).

Quoted in Christopher B. Ricks and Leonard Michaels, The State of the Language, p. 60

Quotes 1960s-1980s, 1980s
Context: From a comparative perspective, the United States is unusual if not unique in the lack of restraints on freedom of expression. It is also unusual in the range and effectiveness of methods employed to restrain freedom of thought... Where the voice of the people is heard, elite groups must insure their voice says the right things… The less the state is able to employ violence in the defense of the interest of the elite groups that effectively dominate it, the more it becomes necessary to devise techniques of ‘manufacture of consent’… Where obedience is guaranteed by violence, rulers may tend towards a ‘behaviourist’ conception; it is enough that people obey; what they think does not matter too much. Where the state lacks means of coercion, it is important to control what people think.

Song lyrics, I'm with Stupid (1995)
Context: I don't know how to break the news, but
It's pretty clear you'll be asked to choose between
What you lack and what you excuse
In this tug of war
You can't say that they didn't warn you
Though you'd rather that they just ignore you
Cause your devices are not working for you anymore What you want, you don't know
You're with stupid now

Variant: We seldom speak of what we have but often of what we lack.
