Passing from the villages to the towns, we may note that at the time of the Norman Conquest there were only about eighty towns in England, and that most of these towns were distinguishable from the villages only by the earthen mounds which surrounded them. Even a town of the first rank cannot have had more than 7,000 or 8,000 inhabitants. Until the second half of the twelfth century, the majority of the burgesses still occupied themselves principally in the cultivation of the common fields, and only a minority specialised in trade or handicraft.[124] Meredith distinguishes four stages in the evolution of a town, but he also makes the important proviso that though the majority of the towns passed through these various stages, yet it cannot be said that any one type of organisation prevailed in any given half-century. Certain factors might combine to make a particular town of great importance and to facilitate its rapid progress; hence the stage of development reached by one town early in the twelfth century might not be attained by another town until a century or more later. The stages are:-- (1) The embryo municipality is but slightly differentiated from a manorial village. (2) The inhabitants increase in number and in wealth and are able to purchase self-government. At this stage a gild merchant is formed. (3) The gild merchant loses its importance; its legislative and judicial work is undertaken by the municipality, whilst the separate craft gilds look after the interests of the various trades. (4) The clear demarcation between town and country breaks down. The capitalist and wage-earning classes emerge and the central government makes inroads into the legislative powers of the municipality and gradually dispenses with the executive work of the crafts. Is it possible to trace a connection between a social and economic condition such as we have described as existing in the manors and towns, and education? It is obvious that there could be little or no demand for education, because, before education is demanded, its value must be perceived. During this period there could not exist any idea of the culture value of education, the value of education for its own sake. Those who held official positions as bailiffs or stewards in connection with manorial estates might find a certain amount of education of value, but neither the demands of commerce nor the amenities of social life were sufficiently insistent to create a wish for education.
