The Muscular does not mold so easily, is less suggestible, is less tractable than the Alimentive or Thoracic but is less likely to revert afterwards.
Built on the Square
¶ "On the Square" is a figurative expression usually applying to a moral tendency. In this sense it is as often possessed by one type as another. But in a purely literal sense the Muscular is actually built on the square. His whole figure is a combination of squares.
The Alimentive is built upon the circle, the Thoracic on the kite-shape but the pure Muscular always tends toward a squareness of outline.
We repeat, he is no more "square" morally than any other type, so do not make the mistake of attributing any more of this virtue to him than to others.
¶ Each type has its own weaknesses and points of strength as differentiated from other types and these are responsible for most of the moral differences between people.
No Type Superior Morally
¶ Since moral weakness comes from type weakness and since each type possesses about as many weaknesses as the others, it follows that no type is superior "morally" to any other and no type is morally inferior to any other.
