Humanism isn’t the worship of humans. It doesn’t hold that humans are of supreme importance.
Humanism is a philosophy of life made by humans for humans about humans. It is about being good without God.
Humanism is a philosophy made by humans. It is not a revelation from God. And because it is made by humans, it is flawed and open for revision as we gain new evidence.
Humanism is about environmental responsibility. It is not humans over Nature but humanity living in harmony with Nature.
Humanity has to learn to work together for the common good based on science and reason, not scripture and divine revelations.
