For religion has been distinguished from superstition not only by philosophers but by our 72 ancestors. Persons who spent whole days in prayer and sacrifice to ensure that their children should outlive them were termed ‘superstitious’ (from superstes, a survivor), and the word later acquired a wider application. Those on the other hand who carefully reviewed and so to speak retraced all the lore of ritual were called ‘religious’ from relegere (to retrace or re-read), like ‘elegant’ from eligere (to select), ‘diligent’ from diligere (to care for), ‘intelligent’ from intellegere (to understand); for all these words contain the same sense of ‘picking out’ (legere) that is present in ‘religious.’a Hence ‘superstitious’ and ‘religious’ came to be terms of censure and approval respectively.
