The Basic Formulation, Or Bare-bones Mechanics, Of

But Our Ways Of Learning About The World Are Strongly Influenced By The Social Preconceptions And Biased Modes Of Thinking That Each Scientist Must Apply To Any Problem. The Stereotype Of A Fully Rational And Objective Scientific Method, With Individual Scientists As Logical (and Interchangeable) Robots, Is Self-serving Mythology.

A Complete Theory Of Evolution Must Acknowledge A Balance Between "external" Forces Of Environment Imposing Selection For Local Adaptation And "internal" Forces Representing Constraints Of Inheritance And Development. Vavilov Placed Too Much Emphasis On Internal Constraints And Downgraded The Power Of Selection. But Western Darwinians Have Erred Equally In Practically Ignoring (while Acknowledging In Theory) The Limits Placed On Selection By Structure And Development What Vavilov And The Older Biologists Would Have Called "laws Of Form.

[evolution Is] One Of The Best Documented, Most Compelling And Exciting Concepts In All Of Science.

Throughout His Last Half-dozen Books, For Example, Arthur Koestler Has Been Conducting A Campaign Against His Own Misunderstanding Of Darwinism. He Hopes To Find Some Ordering Force, Constraining Evolution To Certain Directions And Overriding The Influence Of Natural Selection. [...] Darwinism Is Not The Theory Of Capricious Change That Koestler Imagines. Random Variation May Be The Raw Material Of Change, But Natural Selection Builds Good Design By Rejecting Most Variants While Accepting And Accumulating The Few That Improve Adaptation To Local Environments.

Facts And Theories Are Different Things, Not Rungs In A Hierarchy Of Increasing Certainty. Facts Are The World's Data. Theories Are Structures Of Ideas That Explain And Interpret Facts. Facts Do Not Go Away While Scientists Debate Rival Theories For Explaining Them. Einstein's Theory Of Gravitation Replaced Newton's, But Apples Did Not Suspend Themselves In Mid-air Pending The Outcome.
