What is dialectical thinking?

Dialectical thinking is a concept in personal epistemology: When two ideas contradict each other, both cannot be fully true in the same sense — the tension between them is informative, not a problem to suppress.

Example: In the 1990s, Intel simultaneously held two contradictory beliefs: that their core business depended on memory chips, and that microprocessors were the future. Andy Grove described the moment he asked Gordon Moore, 'If we got kicked out and the board brought in a new CEO, what do you think he would do?' Moore answered without hesitation: 'He would get us out of memories.' The contradiction between what Intel was and what Intel needed to become was not a sign of confused thinking. It was a signal — one that, once surfaced and examined rather than suppressed, enabled one of the most consequential strategic pivots in technology history. Intel exited the memory business and became the dominant microprocessor company for three decades.

This concept is part of Phase 13 (Relationship Mapping) in the How to Think curriculum, which builds the epistemic infrastructure for relationship mapping.
