Could you help me with rephrase the hightlighted sentence, which I am not sure I understand it correctly.
Psychology as the behaviorist views it is a purely objective experimental branch of natural science. Its theoretical goal is the prediction and control of behavior. Introspection forms no essential part of its methods, nor is the scientific value of its data dependent upon the readiness with which they lend themselves to interpretation in terms of consciousness. The behaviorist, in his efforts to get a unitary scheme of animal response, recognizes no dividing line between man and brute. The behavior of man, with all of its refinement and complexity, forms only a part of the behaviorist's total scheme of investigation
here is my work :
Introspection does not form any essential part of its methods
Introspection is not the scientific value of its data dependent upon the readiness with which they lend themselves to interpretation in terms of consciousness.
yeah I stuck in these words a bit.I couldn't figure out which sense the word readiness was used? and what could "they lend themselves" mean?
