Liberty'''.that Condition Of Man In Which Coercion

Ever Since The Beginning Of Modern Science, The Best Minds Have Recognized That "the Range Of Acknowledged Ignorance Will Grow With The Advance Of Science." Unfortunately, The Popular Effect Of This Scientific Advance Has Been A Belief, Seemingly Shared By Many Scientists, That The Range Of Our Ignorance Is Steadily Diminishing And That We Can Therefore Aim At More Comprehensive And Deliberate Control Of All Human Activities. It Is For This Reason That Those Intoxicated By The Advance Of Knowledge So Often Become The Enemies Of Freedom.

This Means That To Entrust To Science - Or To Deliberate Control According To Scientific Principles - More Than Scientific Method Can Achieve May Have Deplorable Effects.

Socialist Thought Owes Its Appeal To The Young Largely To Its Visionary Character; The Very Courage To Indulge In Utopian Thought Is In This Respect A Source Of Strength For Socialism Which Traditional Liberalism Sadly Lacks. Speculation About General Principles Provides An Opportunity For The Play Of The Imagination Of Those Who Are Unencumbered By Much Knowledge Of The Facts Of Present-day Life. Their Ideas Suffer From Inherent Contradictions, And Any Attempt To Put Them Into Practice Must Produce Something Utterly Different From What They Expect.

The Credit Which The Apparent Conformity With Recognized Scientific Standards Can Gain For Seemingly Simple But False Theories May, As The Present Instance Shows, Have Grave Consequences.

It Is Because Every Individual Knows Little And, In Particular, Because We Rarely Know Which Of Us Knows Best Best That We Trust The Independent And Competitive Efforts Of Many To Induce The Emergence Of What We Shall Want When We See It.
