"To search for the human scale, for human function, is to define human needs. ... The whole machine is there, the structure, the nervous system, the arterial system, and this applies to every single one of us exactly and without exception." (32) Once again, the body is viewed as a machine, and somewhat of an equation, where human scale and human function defines human needs. Not all humans have the same scale or functions, so their needs are different, creating a range of human needs that need to be considered.
"If our spirits vary, our skeletons are alike, our muscles are in the same places and perform the same functions: dimensions and mechanism are thus fixed ... human limb objects are in accord with our sense of harmony in that they are in accord with our bodies." (32) Human bodies range in scale, function and needs. While there are groups of people that are very similar with their scale, function, and needs, others do not necessary relate as closely. Bodies in general function similarly to one another, but they are not all the same. No two are identical to one another, and this idea needs to be expressed when understanding that human needs vary and the variation needs to be taken into account.
