Fortitude comes from the Latin word fortitūdō, meaning strength, courage, firmness, or bravery.
Breaking it down:
- fortis = strong, brave, courageous
- -tūdō = a suffix meaning a state or quality
So fortitude literally means “the quality of being strong.”
In classical and Christian thought, fortitude became one of the four cardinal virtues (alongside prudence, justice, and temperance). It doesn’t just mean physical strength—it means the inner strength to endure suffering, hardship, fear, or danger for the sake of what is good.
A simple distinction:
- Courage = facing fear.
- Fortitude = enduring difficulty over time without giving up.
For example, in the philosophy of Thomas Aquinas, fortitude is the virtue that enables a person to remain steadfast in pursuing the good even when confronted with pain, danger, or death.
