1. The essence of justice is to be understood by its beginnings.

2. Committing injustice is naturally good and desired, but suffering injustice is naturally bad and avoided.

Hence,
3. Justice is not grounded in nature (phusis); rather, it is contrary to human nature.

Accordingly,
4. Justice is based entirely on convention (nomos), namely, a social contract that people make with one another whereby they sacrifice their attempts to perform injustices with impunity in order to avoid suffering injustices without recompense.

5. Real men, who can commit injustice with impunity, would not submit to this convention.
