What does it mean to give each person his/her due? How has the meaning of “giving each his due” changed over time?

Giving each person his/her due means providing justice by ensuring the well-being of all the people.

In contemporary time, the concept of “giving each his due” has changed to the understanding of what is due to each person as a human being.

The German philosopher Immanuel Kant argued that if all persons are granted dignity then what is due to each of them is the opportunity to develop their talents and pursue their chosen goals.
