Why cannot a computer replace a textual critic’s judgment when reconstructing a text?

In the field of textual criticism, a computer cannot replace a critic’s judgment because the process of reconstructing a text is fundamentally a historical and discriminatory undertaking that requires human intelligence, common sense, and the ability to evaluate unique, unpredictable circumstances.123

While computers are valuable for mechanical tasks—such as collation, generating concordances, or analyzing stylistic and metrical patterns—they lack the versatility to resolve the complex, "tangled skein" of textual transmission. The primary reasons include:13

• The Necessity of Discrimination: The term "critic" derives from the Greek word for "judge." A critic must constantly discriminate between variants and evaluate the authenticity of readings, a function that cannot be abrogated to a machine.23
• Unique Historical Contexts: Each textual tradition is unique and unpredictable, shaped by a combination of purpose and accident. Because every case is special, there is no universal formula or statistical model that can account for the vast range of human error—such as inattention, ignorance, or deliberate correction—that occurs during transmission.423
• Limitations of Objectivity: Attempts to apply purely objective or mechanical methods to recension often prove illusory. Treating all variants without regard for their literary, stylistic, or historical quality can lead to confusion rather than clarity.3

Ultimately, the best texts are produced by the best scholars, as the work requires the application of reason and experience to bridge the gap between surviving approximations and the original text.125
