This article examines a profound aphorism by Blaise Pascal found in his Pensées, which challenges the common proverb stating that 'habit is a second nature'. Pascal suggests a provocative inversion: that nature itself might be seen as our first or oldest habit. The text explores the philosophical depth of this idea, urging readers to look beyond the apparent absurdity and reconsider the complex relationship between innate characteristics and acquired behaviors. A significant portion of the analysis focuses on linguistic nuances, specifically comparing the Czech language's distinction between 'přirozenost' (nature as an essence or quality) and 'příroda' (the natural world) with the singular terms used in Latin 'natura' and French 'la nature'. By dismantling the rigid boundaries between what is inherent and what is learned, the document reflects on the fluid boundaries of human existence and the historical evolution of philosophical concepts regarding the natural order. This reflection, written in Písek in November 2004, emphasizes the necessity of intellectual openness when examining traditional truths and individual disposition in the context of European thought.
