Greg MacDonald leaves no stone unturned as he places the complexity of second-plane observation into one coherent vision that includes the fundamentals of self-construction, the essential field of observation (freedom of work within the prepared environment), the role of the human tendencies, the construction of developmental facets, and the importance of the elementary child's weekly conference with the teacher. The article reveals an integrated worldview. He suggests that we observe for progress and avoid placing obstacles in the way of the child's true self-construction, and to do this we must be humble and non-judgmental, create with the right degree of difficulty or opportunity, see the physical evidence, and understand the psychical manifestations. The comprehensive nature of this article shows us why observation is an integrating mechanism in building an understanding of human development.
