We can agree with primitive man that food is a basic need, but we differ from him in our food wants because of the wide variety of food we are available compared with him; we have a wide choice. Take fruit for example, not only we enjoy the fruits in his century, but because of modern methods of transport and food preservation, we can also enjoy the more fruits from foreign countries thousands of miles away, whereas primitive man is limited in his choice to the kinds of fruit which actually grow where he lives.
    However, they differ in satisfying their hunger, primitive and civilized men both experience the basic need for food. The same is true of the second of our human need. Clothing is necessary to regulate the heat of our bodies. Since we live in a temperate climate we need more clothes than people living in tropic conditions. Likewise, our clothing needs to be changed with seasons.
    Shelter, the third of our needs, depends on the climate, the skill of the builder, one’s social position and the materials available. The simple shelter of primitive man would not do for us, and yet it satisfies his needs. The three-bedrooms suburban house of the average family would not be grand enough for a rich family, and yet the modern house contains many of the material comforts which were denied to the Kings and Queens of old.
