The man whose whole activity is diverted to inner meditation becomes insensible to all his surroundings. If he loves, it is not to give himself, to blend in fecund union with another being, but to meditate on his love. His passions are mere appearances, being sterile. They are dissipated in futile imaginings, producing nothing external to themselves.
David Emile Durkheim (April 15, 1858 - November 15, 1917) is known as one of the originators of modern sociology. He founded the first European university department of sociology in 1895, and one of the first journals devoted to social science, L'Anne Sociologique in 1896.
