All men have an equal right to the free development of their faculties; they have an equal right to the impartial protection of the state; but it is not true, it is against all the laws of reason and equity, it is against the eternal nature of things, that the indolent man and the laborious man, the spendthrift and the economist, the imprudent and the wise, should obtain and enjoy an equal amount of goods.
Adults interfere with a natural biologic development of the child's motor, visual, mental, and artistic abilities when they try to influence the child's work in the early years.

Knowledge is not a series of self-consistent theories that converges toward an ideal view; it is rather an ever increasing ocean of mutually incompatible (and perhaps even incommensurable) alternatives, each single theory, each fairy tale, each myth that is part of the collection forcing the others into greater articulation and all of them contributing, via this process of competition, to the development of our consciousness.
A new vision of development is emerging. Development is becoming a people-centered process, whose ultimate goal must be the improvement of the human condition.
Inventions reached their limit long ago, and I see no hope for further development.
