For an overview you can take a look at the Tower of Babel and New Age articles on wikipedia.
"Then they said, 'Come, let us build ourselves a city, and a tower with its top in the heavens, and let us make a name for ourselves; otherwise we shall be scattered abroad upon the face of the whole earth.'" (Genesis 11:4)
The New Age (also known as the New Age Movement, New Age spirituality, and Cosmic Humanism) is a decentralized Western social and spiritual movement that seeks "Universal Truth" and the attainment of the highest individual human potential.
Just a little something to thinhk about. Many of the secular movements (Communism, Secular Humanism, Cosmin Humanism) place man at the center and rely on man's ability. So "how's that working for you?".
