Perhaps it is human nature to take things for granted, especially when it is at our disposal. Or perhaps it is a by-product of us not recognizing the true value of things. Maybe it is an unintentional lack of intelligence. If intelligence is the ability to apply or acquire knowledge, where knowledge is the theoretical or practical understanding of a subject would it not stand to say that those who have the best understanding of a subject are the most intelligent. As we define appreciation as understanding a situation fully, we can now recognize the relationship between intelligence and appreciation. If intelligence is knowledge and knowledge is understanding which is pure appreciation, then intelligence is directly linked to appreciation. Therefore, when we take something for granted we are demonstrating a lack of appreciation and therefore a lack of intelligence.
