Life

Physically, life is breathing, drinking, eating, staying warm in the winter, cold in the summer; avoiding oncoming traffic, and not eating yellow snow.

Philosophically, life is being. "I have been, I am, I will be... at least until !!!

Psychologically, life is thinking, acting, feeling, making/finding purpose and meaning, learning self control, shaping and living by principles and values, honesty with your self and others, freely given charitability, and ....

Liberty

Without life, there can be no liberty or it's opposite, slavery.

Whereas life "is," liberty is a behavior identified by human consciousness at the conceptual level.

The concept is best described in the founding documents of my country America. The specific document being The Declaration of Independence.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness.

Happiness

Without life and liberty, there can be no genuine happiness, as it comes from the uniqueness of each individual the freedom to make personal choices.
