Not done Sir, but doing.

"....the physicalist doctrines of present-day behaviourists are based not so much on the empirical study of the brain or of conscious behaviour as on purely a priori considerations. [Thus] originated Watson's famous manifesto, which declared that henceforth the genuinely scientific psychologist should banish 'metaphysical' terms like consciousness, sensation and mind, because they were not part of the 'accepted scientific framework'. Watson, he tells us, was brought up on the late-nineteenth-century textbook of Tait and Thompson (later Lord Kelvin) which put forward a simple and attractive monistic theory of the universe. There was only one type of substance, namely matter; one type of agency, namely energy (capable of transformation); both were strictly 'conserved'; space and time were absolute; and all action was to be pictured in terms of a mechanical model.... [However] as a universally valid world-view, this nineteenth-century conception has now been rendered wholly out of date by the revolutionary changes in twentieth-century physics-by the theory of relativity, the quantum theory, and above all by researchers into the inner structure of the atom.... The alleged causal laws turn out to be merely approximate statistical laws. Neither space nor time is absolute. Matter is not indestructible. The observer can no longer be ignored. And the principle of indeterminacy is universally accepted."
