Abstract
Within a weak system $${{{\sf WKVS}}}$$WKVS of intuitionistic analysis one may prove, using the Weak Fan Theorem as an additional axiom, a completeness theorem for intuitionistic first-order predicate logic relative to validity in generalized Beth models as well as a completeness theorem for classical first-order predicate logic relative to validity in intuitionistic structures. Conversely, each of these theorems implies over $${{{\sf WKVS}}}$$WKVS the Weak Fan Theorem.
