But the human consciousness of self transcends, I suggest, all purely biological thought. I may put it like this: I have little doubt that animals are conscious, and especially that they feel pain and that a dog can be full of joy when his master returns. But I conjecture that only a human being capable of speech can reflect upon himself. I think that every organism has a programme. But I also think that only a human being can be conscious of parts of this programme, and revise them critically.
Most organisms, if not all, are programmed to explore their environment, taking risks in doing so. But they do not take these risks consciously. Though they have an instinct for self preservation, they are not aware of death. It is only man who may consciously face death in his search for knowledge.
A higher animal may have a character: it may have what we may call virtues or vices. A dog may be brave, affable, and loyal; or it may be vicious and treacherous. But I think that only a man can make an effort to become a better man: to master his fears, his laziness, his selfishness; to get over his lack of self control.
In all these matters it is the anchorage of the self in World 3 that makes the difference. The basis of it is human language which makes it possible for us to be not only subjects, centres of action, but also objects of our own critical thought, of our own critical judgement. This is made possible by the social character of language; by the fact that we can speak about other people, and that we can understand them when they speak about themselves.
The social character of language together with the fact that we owe our status as selves – our humanity, our rationality – to language, and thus to others, seems to me important. As selves, as human beings, we are all products of World 3 which, in its turn, is a product of countless human minds.
I have described World 3 as consisting of the products of the human mind. But human minds react, in their turn, to these products: there is a feedback. The mind of a painter, for example, or of an engineer, is greatly influenced by the very objects on which he is working. And he is also influenced by the work of others, predecessors as well as contemporaries. This influence is both conscious and unconscious. It bears upon expectations, upon preferences, upon programmes. In so far as we are the products of other minds, and of our own minds, we ourselves may be said to belong to World 3. [!!!]
