Four-Philosophy Ensemble

This is a trope applying to the dynamics of groups of four. While the Four-Temperament Ensemble seeks to classify members by their personality, this trope classifies members by their outlook, or life philosophy, especially as demonstrated when the Group is faced by a problem or challenge. Keep in mind that this trope crops up in more character-driven works and will probably be absent from a work where the group of heroes are more cohesive or single-minded. That is to say, if there isn't much argument within the group, then they never have much chance to demonstrate the differing traits making up this trope. The dynamics for this trope are very effective because it combines the best parts of a Good Cop/Bad Cop or a Red Oni, Blue Oni binary (The Cynic vs The Optimist) and a Power Trio, (The Cynic - The Realist - The Optimist) placing The Realist in between the two opposing views, along with a fourth member (The Apathetic) to contrast all of them at once, including a fourth dimension to the argument, and even the potential for a fifth to be conflicted over the issue, often resulting in a Three Plus Two. All of this in a package that can even be coupled with the Four-Temperament Ensemble for double the fun. This is some serious Cast Calculus.
