  According to Haslanger, in trying to be objective about our world and function within it, we go about trying to discover things’ natures. An object’s nature is essential to it, and any change to it will inevitably destroy it. An object cannot exist without those properties that constitute its nature. Discovering an object’s nature enables us to explain the behaviour of that object under normal circumstances. This means that in practical decision-making, we must be attentive to objects’ natures (Haslanger 1993, 103, 105). She writes: “It won’t do to try to fry an egg on a paper plate; there is no point in trying to teach a rock how to read. Because the world is not infinitely malleable to our wants or needs, reasonable decision making will accommodate ‘how things are’, where this is understood as accommodating the natures of things, the background conditions constraining our actions” (Haslanger 1993, 105).
