[51] Again: to him who has acquired wisdom by meditation and practise, sight is given. For after the practical life of youth comes the contemplative life of old age, which is the most excellent and the most sacred, which God has sent down from above to take its place in the stern like a pilot, and has given the helm into his hand as being able to guide the course of all earthly things; for without contemplation based on knowledge, there is nothing whatever that is good done.
