This text explores the nature of sense and meaningfulness within the context of language and human action. The author distinguishes between an intelligible sentence and a mere cluster of words or a child's babbling, which lacks substantive meaning. The meaningfulness of action is defined here through its purposefulness, goal-orientation, and efficiency. A significant portion of the reflection is dedicated to the nature of the symbol, emphasizing that individual signs, such as a dot or a dash in Morse code, do not constitute a symbol on their own. They only become a symbol as a whole within a specific system. The text also suggests that the practical advantage of using a symbol does not alter its fundamental meaning. This brief reflection from January 1944 represents a philosophical attempt to define the boundaries between randomness and the structured meaning that forms the basis of human communication and rational behavior. Overall, it provides a dense analysis of what makes an expression or act intelligible and functional within the human world.
