1. The document discusses three potential traits that define humanity: understanding and language, freedom and self-responsibility, and unlimited desire. 2. It argues that unlimited desire, which drives humans to constantly search for meaning, happiness, and fulfillment through questions, choices, love and communion, may be the most fundamental human trait. 3. This trait of unlimited desire can justify fundamental personal rights like the right to life, freedom, and due process, which in turn other rights are derived from, in order to ensure humans can fulfill their desires. However, recognizing another's humanity ultimately requires choice and acknowledgement of their desires too.
