"I am a man, I consider nothing that is human alien to me"

This quote is attributed to Terence, a Roman playwright who lived from about 185 to 159 BC. He was born in North Africa and brought to Rome as a slave, but was later freed and became a famous writer and actor.

The quote reflects Terence's belief in the essential unity of human nature, and suggests that he believed that all people share common experiences and emotions, regardless of their social status, background, or beliefs. He placed great emphasis on the importance of empathy and understanding, and believed that it was essential to be able to see oneself in another person's position in order to truly understand them.

The quote has been widely used in discussions of human rights, social justice, and the importance of empathy and compassion. It has been seen as a call to recognize the essential humanity of all people, and to work towards greater understanding and cooperation across cultural, racial, and other barriers.
