Lynceus (Argonaut) In Greek mythology, Lynceus or (Ancient Greek: Λυγκεύς ) was the jealous murderer of Castor, along with his brother, Idas. Idas and Lynceus murdered Castor because they all (along with Polydeuces) sought Phoebe and Hilaeira, daughters of Leucippus (who was also Idas and Lynceus' uncle in some versions). Lynceus was one of the Argonauts and he participated in the hunt for the Calydonian Boar. He was a son of Aphareus and Arene and was said to have excellent sight, even able to see through trees, walls and underground.
Atomism (social) Atomism or social atomism is a sociological theory arising from the scientific notion "atomic theory", coined by the ancient Greek philosopher Democritus and the Roman philosopher Lucretius. In the scientific rendering of the word, atomism refers to the notion that all matter in the universe is composed of basic indivisible components, or atoms. When placed into the field of sociology, atomism assigns the individual as the basic unit of analysis for all implications of social life. This theory refers to "the tendecy for society to be made up of a collection of self-interested and largely self-sufficient individuals, operating as separate atoms". Therefore, all social values, institutions, developments and procedures evolve entirely out of the interests and actions of the individuals who inhabit any particular society. The individual is the ‘atom’ of society and therefore the only true object of concern and analysis.
