This reflection examines the semantic and ontological distinction between the terms "discovery" and "invention," which are often conflated in everyday language. The author points out that the Czech language lacks an etymologically precise term for invention that would clearly signify the creation of something entirely new, as opposed to merely finding something already extant. The text defines discoveries as facts or entities that have existed in the world since time immemorial, merely waiting to be revealed and presented to others. In contrast, inventions are the products of active human creative activity, construction, or cultivation. These are entities that did not exist prior to human intervention, and their existence is contingent upon the specific actions of their creator. Thus, an invention represents an active shaping of reality, whereas a discovery is a passive recognition of a pre-existing state. The article emphasizes that while discovered things are permanent parts of the world, the existence of inventions is temporally limited and depends on their physical integrity, as they can perish or be destroyed. This distinction is crucial for precise discourse on the nature of human knowledge and creation.
