# The Computer Metaphor Cannot Explain the Brain by Robert Provine > “My response to the inquiry about questions that are no longer asked is to reframe it and suggest instead a common class of missing questions, those associated with obsolete and inappropriate metaphors. Metaphor is a powerful cognitive tool, which, like all models, clarifies thinking when appropriate, but constrains it when inappropriate. Science is full of them. My professional specialties of neuroscience and biopsychology has mind/brain metaphors ranging from Locke's ancient blank slate (tabula rasa), to the more technologically advanced switchboard, and the metaphor de jour, the computer. None do justice to the brain as a soggy lump of wetware, but linger as cognitive/linguistic models. Natural selection in the realm of metaphors is slow and imperfect. Witness the reference to DNA as a "blueprint" for an organism, when Dawkins' "recipe" metaphor more accurately reflects DNA's incoding of instructions for organismic assembly.” > **— Robert Provine**, *2001, Edge Annual Question, “What Questions Have Disappeared?”* ## Sources and Context - **Direct Edge response and surrounding essay:** [Obsolete and Inappropriate Metaphors](https://www.edge.org/response-detail/12033) — Edge published this exact passage in its 2001 Annual Question collection, *WHAT QUESTIONS HAVE DISAPPEARED?*.
