And that is that we all in this room learned how to walk, how to talk, not by being taught how to talk, or taught how to walk, but by interacting with the world, by having certain results as a consequence of being able to ask for something, or being able to stand up and reach it.
Isto é, todos nós nesta sala aprendemos a andar, a falar, não por alguém nos ter ensinado a falar ou a andar, mas por interagirmos com o mundo, por termos certos resultados em virtude de conseguirmos pedir algo, ou de conseguirmos levantar-nos e alcançá-lo.
