 Rh make discoveries for himself; with the death of the discoverer the discovery also becomes extinct, and each has to start anew from the very beginning. It is only through society that the experience and knowledge of former generations can be preserved, perpetuated, and developed. In a group or body a few may die, but the group, as such, does not. It remains. Knowledge in the use of tools is not born with man, but is acquired later. Mental tradition, such as is possible only in society, is therefore necessary.

While these special characteristics of man are inseparable from his social life, they also stand in strong relation to each other. These characteristics have not been developed singly, but all have progressed in common. That thought and language can exist and develop only in common is known to everyone who has but tried to think of the nature of his own thoughts. When we think or consider, we, in fact, talk to ourselves; we observe then that it is impossible for us to think clearly without using words. Where we do not think with words our thoughts remain indistinct and we can not combine the various thoughts. Every one can realize this from his own experience. This is because so-called abstract reason is perceptive thought and can take place only by means of perceptions. Perceptions we can designate and hold only by means of names. Every attempt to broaden our minds, every attempt to advance our knowledge must begin by distinguishing and classifying by means of names or by giving to the old ones a more precise meaning. Language is the body of the mind, the material by which all human science can be built up.

The difference between the human mind and the animal mind was very aptly shown by Schopenhauer.
