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

To give each person his/her due is providing justice to everyone by ensuring the wellbeing of all.

The idea of providing justice to everyone i.e. providing all their due is the integral part of present day life. It has continued to be an important part of our present day understanding of justice.

However, the idea has changed from the time of Plato (Political Thinker), today the notion of what is just is closely linked to providing justice to everyone as a human being.

A German philosopher Immanuel Kant argued, that if all person are granted dignity, then what is due to them is the opportunity to develop their talents.
