Summary
It is a common view in some fields that logic has little to do with search. For example, Paul Thagard (2005) in Mind: Introduction to Cognitive Science states on page 45: “In logic-based systems, the fundamental operation of thinking is logical deduction, but from the perspective of rule-based systems, the fundamental operation of thinking is search.”
Similarly, Jonathan Baron (2008) in his textbook Thinking and Deciding writes on page 6: “Thinking about actions, beliefs and personal goals can all be described in terms of a common framework, which asserts that thinking consists of search and inference. We search for certain objects and then make inferences from and about the objects we have found.” On page 97, Baron states that formal logic is not a complete theory of thinking because it “covers only inference”.
