From the Latin, Res Publica Rationis is "The Commonwealth of Reason". The commonwealth is not defined by its geographic extent; rather, it is defined by its guiding principles and the people who practice them. These principles are:

• Reason, which is the thought one gives to his action.
• Honor, which is the respect that he gives to others and to himself.
• Responsibility, the product of reason and honor, which is the knowledge that one must live his life to advance his own self-interest, to respect the right of others to do the same, and to accept the just consequences of failing to do these things.
• Liberty, which comes from reason, honor, and responsibility, and is the ability to act independently, free from outside coersion.

The motto of Res Publica Rationis is A Facta, Sum, which is "From action, existence". The commonwealth is defined not by the words of its members, but by their actions. Words are soon forgotten, but the product of action remains, to be seen by those who look upon it.

Symbology

The colors of the commonwealth's ensign are:

• Black, which symbolizes determination.
• Gold, which symbolizes the wealth of liberty.
• Red, which symbolizes honor.

Gold is flanked by black and red, symbolizing that wealth is the product of determination and honor, rather than a thing in itself.

On the coat of arms, the book symbolizes reason, and the anvil and carpenter's square symbolize hard but productive work.
