In the book Out of The Silent Planet, how does Out Of The Silent Planet criticize the society of Earth, OUR society? also give examples.

This story is primarily a Christian allegory. Lewis is pointing out that man on Earth is fallen. Man (people) have been seduced by dark forces to turn away from the light of God and seek meaning in greed and endless desire. The human condition must turn away from material delights towards a higher benevolent power if it is ever to free itself from sin and temptation. Consider our own materialistic society filled with endless consumption and external validation through material possessions.
