Socrates, Plato, and Aristotle were ancient Greek philosophers whose teachings on ethics still influence business ethics today. The Socratic method encourages independent thinking and questioning beliefs. Plato saw education as important for a healthy society and believed ethics could be cultivated from a young age. Aristotle thought virtue was the highest goal and could not be taught directly, but rather through creating the right environment. Modern philosophers like Kant and Bentham also shaped business ethics with principles like treating people as ends rather than means and considering outcomes. Cultural values from the Philippines like utang na loob (reciprocity), filial piety, and bahala na (fatalism) also impact how business is conducted, especially regarding ethical issues.
