One of the great inventions of the post-industrial revolution era is the steel I-beam. The I-beam works because it leverages pieces that face in different and opposite directions. Two thin steel “flanges” run parallel with each other, with a perpendicular steel “web” connecting the two and running the distance between them. It gets its name because when viewed in a cross section the metal pieces make an “I”. The I-beam is such an ingenious piece of engineering because compared to traditional steel beams the I-beam is made up of much less steel without sacrificing any of its strength. This means I-beams can be used in large construction projects, spanning vast distances and supporting weight that would otherwise be impossible.
Tolerance plays a similar role. In our democracy there are as many different viewpoints and opinions as there are participants. Although these differences have notably been the source of friction in our society, they are what gives our democracy strength.
