...there is need for a person to be generally educated. Otherwise you shrivel up much too soon. Whether this means reading the bible (I read the New Testament every few years) or reading the great 19th century novelists (the greatest and shrewdest judge of people and of society who ever lived), or classical philosophy (which I cannot read--it puts me to sleep immediately), or history (which is secondary). What matters is that the knowledge worker, by the time he or she reaches middle age, has developed and nourished a human being rather than a tax accountant or a hydraulic engineer.
