In all thinking we are interpreting signs. In obvious cases this is readily admitted. In the more complex cases of mathematics and grammar more complicated forms of the same activity only are involved.
This is hidden from us by an uncritical use of symbols, favouring analyses of 'meaning' and 'thinking' which are mainly occupied with mirages due to 'linguistic refraction.'
We must begin therefore with Interpretation.
- Our Interpretation of any sign is our psychological reaction to it, as determined by our past experience in similar situations, and by our present experience.
If this is stated with due care in terms of causal contexts or correlated groups we get an account of judgment, belief and interpretation which places the psychology of thinking on the same level as the other inductive sciences, and incidentally disposes of the 'Problem of Truth.'
A theory of thinking which discards mystical relations between the knower and the known and treats knowledge as a causal affair open to ordinary scientific investigation, is one which will appeal to common-sense inquirers.
Sign-situations are always linked in chains and the simplest case of such a sign-chain is best studied in Perception.
- Throughout almost all our life we are treating things as signs. All experience, using the word in the widest possible sense, is either enjoyed or interpreted (i.e., treated as a sign) or both, and very little of it escapes some degree of interpretation. An account of the process of Interpretation is thus the key to the understanding of the Sign-situation, and therefore the beginning of wisdom. It is astonishing that although the need for such an account has long been a commonplace in psychology, those concerned with the criticism and organization of our knowledge have with few exceptions entirely ignored the consequences of its neglect.
