This paper is to investigate human mind and the creative aspect of language use from the internalistic and biolinguistic perspectives. Biolinguistics examines the language faculty regarded as the internalized biological result of human mind. Accordingly, the study of human language deals with questions of language faculty, linguistic creativity, and generative creativity, and pursues the mechanisms that make language use possible. The creative aspect of language use is investigated as the central fact to any significant linguistic theory with some properties such as unboundedness, stimulus freedom, and coherence and appropriateness to circumstance. It is suggested that Chomskyan internalism deals with language faculty underlying the creative aspect of language use and provides the explanatory and fruitful scientific theory. As the standard arguments that syntax is innate, the creative aspect of language use is also innate to a large extent in humans. To conclude, the creative aspect of language use is an important aspect of the language faculty, and language users can acquire the ability to use their language creatively in language acquisition.
