## Statement

Among contemporary logicians, the distinction between psychology and logic is widely accepted. However, there are a few philosophers of logic who consider that logical laws can be regarded as constitutive of rational thought.

For example, Paul Boghossian argues that to possess a concept is, in part, a disposition to draw inferences in accordance with some basic rules. He claims that some inferential principles are constitutive of contentful thought and are part of what it means to have beliefs at all.

Robert Hanna contends that logic arises from an innate protological cognitive capacity that is necessarily shared by all rational human animals. This is a 'protologic' that is "structurally distinct from all classical and nonclassical systems, but unifies the many logics through its role in the construction of all logical systems".

Jessica Leech claims that the laws of logic can be considered to be laws of thought, understood as constitutive norms of thought.

However, none of these authors identify basic rules, protologic, or laws of thought with the "three laws".
