From the most ancient times down to our own era, all the ideologies created/believed by humanity have eventually reached a crisis-point. This crisis of confidence occurs when it becomes obvious to the majority that the benefits of any particular ideology to it's adherants are outweighed by the disadvantages inflicted by that same ideology.
Since European Civilization's high water mark in the Victorian Age, progressive thinkers have encouraged us to abandon the 'old religious attitudes' that underpinned that era's achievements. An 'enlightened' aetheist/socialist ideology developed from the ideas of Darwin, Marx and Freud has been substituted on the promise that when allied to modern technology, this scientific world-view would create a 'New Jerusalem'; amidst which all our spiritual and material needs would be provided for in abundance. As we survey the social wreckage of our 'modern' Western World, it seems clear that this aetheist/socialist ideology upon which orthodox Western thought is now based, has reached that crisis-point.
Far from creating world peace, the 'dog eat dog' attitudes of Darwinism led to the mass slaughters of the 20'th Century as unfettered by religious constraint, but driven by quasi-religious fervour; rival Imperialist, Marxist, Fascist/Nazi, Nationalist and Capitalist factions mercilessly attempted to eradicate each other worldwide. Similarly the egalitarian socialism of Marx led not to the predicted 'Utopia' but to 'Red Terror' and the soulless tyrannies predicted by George Orwell.
Socially, the aetheistic, non-judgemental 'liberal' attitudes promoted by Freud have also failed to deliver as promised; creating obscene differences of weath and power in which tiny 'elites' exist alongside immense multitudes known as the 'underclass'; crime, drug abuse, abortion, family breakdown, mental illness and class/racial hatreds have all vastly increased. This fraught situation can only be compared to Ancient Rome's final years and then as now, many within a deeply troubled population turned to traditional and/or militant religion.
Today's aetheism versus faith, democracy versus totalitarianism, and egalitarianism versus meritocracy debates amongst others, are just symptoms of this far greater crisis; the failure of orthodox Western thought and will not be decided by logic or science alone, but by the outcome of this greater crisis.
