We cannot but think of today's tendency for people to refuse to accept responsibility for their brothers and sisters. Symptoms of this trend include the lack of solidarity towards society's weakest members-such as the elderly, the infirm, immigrants, children- and the indifference frequently found in relations between the world's peoples even when basic values such as survival, freedom and peace are involved. (Papal Encyclical, Evangelium Vitae, 25 March 1995).
