It needs a minimal argument to convince the average thinking person of the great importance of memory. Although even then, very few begin to realise just how important the function of the mind is, that has to do with the retail of mental impressions
The first thought of an average person, when asked to consider the importance of memory, is its use in everyday happenings along developed and cultivated lines, as contrasted with the lesser degrees of its development.
In short, one generally thinks of memory in its phase of a "good memory" as contrasted with the opposite phase of a "poor memory." But there is a much broader and fuller meaning of the term than that of even this significant phase.
