What this quote means

Guyau defines morality as a practical science, not a set of arbitrary rules. It aims to understand the conditions that allow life to flourish. This naturalistic perspective places ethics in the concrete reality of existence. It invites us to base our moral choices on knowledge of life and its needs.

How to apply it daily

When facing a moral decision, evaluate whether it promotes life, health, and growth. Use these criteria to guide your choice.
