Oak trees don't reason. Lobsters wander into baited traps. So how is Humankind capable of asking... "Why?" Subjectivity offers the human organism a point-of-view on its own internal operations.

To experience the "Me Mechanism" that reliably develops in all seven billion of our planet's: "Beings In Time."
