New Year's Address to the Nation (1990)
Context: The worst thing is that we live in a contaminated moral environment. We fell morally ill because we became used to saying something different from what we thought. We learned not to believe in anything, to ignore one another, to care only about ourselves. Concepts such as love, friendship, compassion, humility or forgiveness lost their depth and dimension, and for many of us they represented only psychological peculiarities, or they resembled gone-astray greetings from ancient times, a little ridiculous in the era of computers and spaceships.

"Le concept de l'absolu, d'où découlent, dans le domaine moral, les lois ou normes morales, constitue, le principe d'identité, qui est la loi fondamentale de la pensée; il en découle les normes logiques qui régissent la pensée dans le domaine de la science."

Preface
The Right to Be Happy (1927)
Context: It has taken us centuries of thought and mockery to shake the medieval system; thought and mockery here and now are required to prevent the mechanists from building another. Without falling into a mystical vitalism that reverences organic nature as sacred, we can at least try rather to serve than to subdue the prancing seas of life. With this in view I have taken as impulses, instincts, or needs certain driving forces in the human species as we know it at present, and argued for such social and economic changes as will give them new, free, and varied expression. To take even this first step towards a happy society is a herculean task. After it has been accomplished, generations to come will see what the creature will do next. We none of us know; and we should be thoroughly on our guard against all those who pretend that they do.
