Kantianism: when we treat people as means to themselves, as opposed to means to an end. Basically, we're not out to use them. It's pretty much the opposite of Machiavellianism, and is based on the philosophy of Immanuel Kant.
Humanism: valuing the dignity and worth of each individual person.
Faith in humanity: we believe that people are fundamentally good.
