Courage is not a virtue of value among other personal values like love or fidelity. It is the foundation that underlies and gives reality to all other virtues and personal values. Without courage our love pales into mere dependency. Without courage our fidelity becomes conformism.
One does not become fully human painlessly.
Many people feel they are powerless to do anything effective with their lives. It takes courage to break out of the settled mold, but most find conformity more comfortable. This is why the opposite of courage in our society is not cowardice, it's conformity.
