The remark by Descartes is indeed profound because the saying might be obvious but its implication is undeniably thought-provoking. The usage of the term, ‘think’ before ‘am’ is significant in the sense that it establishes the supremacy of the need to indulge in critical thinking and introspection before accepting anything. According to Descartes, the mere condition of breathing is not a sufficient proof of my existence but it is the ability to think and hence doubt, which establishes the proof of the existence of the mind.
