The Republic. Socrates stands before his troupe of Greeks and lectures at length about the perfect society.
Socrates: All fiction stories must have a strong moral in which the good is rewarded and evil punished; if not, society will decay and die.
Glaucon: Well, that’s perfectly clear, Socrates.
Socrates: And, in our state, the color blue will be outlawed, too, because the color blue represents effervescence, and, as we all know, effervescence is flighty, and that isn’t justice and we will only allow colors that represent justice.
Socrates: And our society will require a lot of electrolytes.
Glaucon: What is an electrolyte, Socrates?
Socrates: Electrolytes are essential for basic life functioning, such as maintaining electrical neutrality in cells, generating and conducting action potentials in the nerves and muscles. Sodium, potassium, and chloride are the significant electrolytes along with magnesium, calcium, phosphate, and bicarbonates. Electrolytes come from our food and fluids.
Glaucon: Wow, Socrates; it sounds like we need electrolytes in our republic.
Socrates: Yes, but not blue-colored electrolytes.
Glaucon: Of course not, Socrates; of course not blue electrolytes.
