Arnold Toynbee has described our western civilization in the twentieth century as a rationalistic and secular culture. In the sense that an awareness of the importance of science is the starting point of the thinking of our day the generalization seems true. We prize the realism of the objective, analytical approach of science. In a turbulent and swiftly moving age we have substituted relativism for older values once confidently assumed to have universal validity. We have seen scepticism, born of twentieth-century events, erode an old and dynamic belief in progress. We observe Protestantism, its old orthodoxy shaken, striving to make the Christian tradition meaningful and significant for a materialistic generation. We watch the protagonists of democracy striving to hold fast to essential human values and to protect basic freedoms in an age of fear and power.
