What is defined as the will to stand up for what is right, regardless of the personal cost?

The concept being described is moral courage, which refers to the ability to stand up for what one believes is right, even when it may come at a personal cost. This type of courage involves making ethical choices and taking actions that align with one's values, despite facing potential backlash or difficulties. It emphasizes a commitment to integrity and the moral principles that guide one's behavior. People exhibiting moral courage are willing to confront injustice, advocate for others, and uphold their beliefs in the face of opposition.

In contrast, resilience pertains to one's ability to recover from setbacks and adapt to adversity, rather than making choices about right and wrong. Physical courage refers specifically to the bravery shown in the face of physical danger or threat, which does not encompass the moral decision-making aspect. Hardiness of spirit typically describes a broader psychological resilience, focusing on a person's overall mental fortitude. Moral courage, therefore, distinctly captures the essence of standing for ethical principles, making it the correct answer in this context.
