The problem with humanities is that they are not backwards-compatible. In most other fields of human knowledge even a complete paradigm switch does not erase the basic truths that form a foundation of the science – and human experience.

Introduction of the concept of quarks or the relativity theory did not falsify the laws of gravity or chemical formulas. Should a medic spend a year in coma, his knowledge of the most recent trends will surely be crippled. However, he could still prescribe aspirin – and it will work.
