Well you have me there but can you actually explain the difference between believing in anything and believing in nothing?
Think about it. What could believing in anything actually mean. It has to mean that you have NO core beliefs - you will listen and believe anything you hear. Believing in "anything" and believing in "nothing" are not actually opposites. Believing in "something" is the opposite of believing in "nothing".
In any case, the quote above is just nonsense. If it's not then explain to me what you think it means.
What it means is that people will latch onto something, even if it is self contradicting, illogical, irrational, etc.
As history has shown, in a secular society that situation has given rise to the most destructive forces in history.
The simple reason is that most non-God based belief systems ultimately put their faith in man, who then in turn creates their own morality.
Ravi Zacharias once made an astute point that the horrors of the Holocaust were made possible in the lecture halls of German Universities, where the philosophies of the time squashed religion and elevated the self. Nietsche’s groundwork for existentialism and postmodernism are prime examples. Hegel’s work that denied the existence of absolutes also played a role. There are other examples as well.
