sources of motivation

[Доброгнева]

It may be able to continue with other, though less vital, sources of motivation. Помогите с переводом этого предложения.

Контекст такой:
As we will see with Benjamin Franklin and many others, the ethic can take on a secular life of its own. It may be able to continue with other, though less vital, sources of motiva¬tion. It remains for us to see what this new secular vision and motivation will be.
