You know, when we talk about a 'concept,' it feels so simple, right? It's just an idea, a thought in our head. But dig a little deeper, and it gets fascinatingly complex, especially when you look back at how thinkers wrestled with this very notion centuries ago.
Imagine trying to explain how words connect to the world. That's where concepts come in. For medieval philosophers, concepts were the crucial bridge. They weren't just abstract notions; they were seen as the fundamental building blocks of meaning. Think of them as natural signs, like a footprint naturally signifies that an animal has passed by. Words, on the other hand, were like conventional signs – they only meant something because we agreed they did, like a traffic light. These spoken or written words were essentially marks for concepts, and concepts, in turn, were the direct link to reality.
This idea wasn't born in a vacuum. It was heavily influenced by ancient thinkers like Aristotle and Augustine. Aristotle, for instance, had this powerful idea that our minds are like a 'tabula rasa' – a blank slate. Everything we know, all our concepts, ultimately come from our senses. We experience the world, and our minds, with their innate cognitive powers, abstract from those experiences to form general ideas. So, a concept isn't just plucked from thin air; it has a natural, almost causal, connection to the thing it represents. It's like the concept of 'dog' is naturally linked to actual dogs through our sensory experiences and cognitive processing.
This natural link is key. It means a concept has a direct, law-like relationship with the things it signifies. Conventional signs – the words we use – get their meaning indirectly. They are linked to concepts, and it's through those concepts that they ultimately point to the world. John Buridan, a medieval thinker, put it quite neatly: words signify things 'by the mediation of their concepts.' The things we ultimately refer to are the 'ultimate significata,' while the concepts themselves are the 'immediate significata.'
It’s a bit like a chain reaction of meaning. You hear a word, that word triggers a concept in your mind, and that concept connects you to the actual thing or idea in the world. And this whole system of signification, how words relate to things and how propositions come to mean what they do, was fundamental to how medieval thinkers understood truth and reasoning. It’s a rich tapestry of thought, showing that even something as seemingly simple as a 'concept' has a deep and intricate history.
