is our definitions of words based in properties ? for example we have a banana.We define banana from its image? but if this true if we find something that looks like banana but smells like hot dog then it is a banana? but even if we give banana some properties these properties come arbitrary..so how we define something ?
A definition describes the area which collects risk and opportunity in relation to a given goal. The properties included in a definition depend on the definition's purpose.
If the purpose is to illustrate a children’s book of colors, it is sufficient to show how a banana has a certain shape and is yellow. If the purpose is to place a banana scientifically among all plants, it is necessary to say that one banana tree species is, for example, Musa acuminata. If the purpose is to ship bananas from the forest to the store, it is necessary to describe the degree of ripeness before the banana can be harvested and sold.
