  But although intuitionists may not have confused concepts and properties, they did seem to believe that there is a certain isomorphism between the structure of our concepts and the nature of the world, such that a proper analysis of our concepts would reveal to us the nature of the corresponding property or thing. This belief is not obviously confused, but the examples of heat and water seem to show that it cannot be accepted as it stands. Intuitionists need not, however, rest their view about the property of goodness on a general thesis about the relation of concepts and properties. All they need do is identify what it is about certain concepts, like the concepts of water and heat, that provides us with reasons to think that the corresponding properties are different, and then argue that these reasons do not apply to the concept of goodness.
