According to Karl Barth, conscience plays an important function in interpreting life. Conscience is that inner voice that guides a person's ethical decision-making process. It is the voice of reason that helps us recognize what is ideal or wrong, excellent or bad. It is a natural sense of justice, which helps us see the fact amidst clashing concepts, feelings, and viewpoints. Barth thinks that by listening to our conscience, we can make sound decisions and lead a meaningful life. Conscience, therefore, is the ideal interpreter of life as it assists us understand our purpose and meaning, enabling us to make ethical options that line up with our worths and beliefs.
"Life is life - whether in a cat, or dog or man. There is no difference there between a cat or a man. The idea of difference is a human conception for man's own advantage"
