It is common to find well-intentioned people showing their passionate defence of one value or another. Some political parties advocate responsibility, others equality, etc. However, the laws of nature tell us we cannot consider these values separately, as neither forces nor symmetries are available “à la carte”! We may not choose them according to our mood or inclination. All symmetries are inextricably linked, as are all forces. Therefore, equality, fairness, reciprocity, solidarity, truth, proportionality, responsibility, freedom, etc., are interdependent values which only become ethical values when acting together. A boss can not be responsible if he does not act in a proportionate manner. How can healthy relationships be maintained when reciprocal behaviour is unfair or unequal? Let us pursue our study of ethics and its multiple forms.
