What this quote means

Hilary Putnam overturns the traditional conception of meaning. According to him, the meaning of words does not reside solely in our minds, but depends on social context and environment. For example, the word 'water' has a meaning fixed by physical reality, not by our thoughts. This idea has profound implications for philosophy of language and mind: our understanding of the world is anchored in a shared reality, not just our subjectivity.

How to apply it daily

In a conversation, become aware that the words you use have meanings shaped by your culture. Try to clarify important terms to ensure you are indeed talking about the same thing.
