Progress in physics has been marked by bold hypotheses dealing with imponderable forces, and by experiments disclosing hidden properties of matter. The hypothetical ether has been as fruitful in the liberation of thought as the demonstration of the existence of the X-rays.
We may dispute the conclusions of M. Hannequin, but no one will refuse to recognise, as he does, that atomic theories occupy a preponderating part in the doctrines of physics; and the position which they have thus conquered gives them, in a way, the right of saying that they rest on a real principle.
Pascal’s treatise, while still retaining so much of the old traditional physics, was made an object of lively attack by the Jesuit Rector of the College of Paris, Stephen Noël.
If there is any truth in the received doctrines of physics, that contrast between living and inert matter, on which Bichat lays so much stress, does not exist.
No balloon, as we have already seen, should be entirely inflated at the beginning of a journey. Blanchard had a narrow escape from being the victim of his ignorance of physics, and it is a wonder he was not left to the mercy of fate in a burst balloon, at several thousand feet above the earth.
All that we can know empirically is approximate and liable to exceptions; the exact laws that are assumed in physics are known to be somewhere near the truth, but are not known to be true just as they stand. The laws that we actually know empirically have the form of the traditional causal laws, except that they are not to be regarded as universal or necessary.
In fact, attempts have been made, by the help of deductions from the data of physics, to lay down an approximate limit to the number of millions of years which have elapsed since the earth was habitable by living beings. If the conclusions thus reached should stand the test of further investigation, they will undoubtedly be very valuable.
What can we learn by observation and experiment? Nothing, so far as physics is concerned, except immediate data of sense: certain patches of colour, sounds, tastes, smells, etc., with certain spatio-temporal relations.
The resolute worker resumed his indefatigable labours with an ardour greater than ever, for now he was haunted by a noble ambition, that of becoming a teacher of the superior grade, and of "talking plants and animals" in a chair of the faculty. With this end in view he added to his two diplomas those of mathematics and physics a third certificate, that of natural sciences.
At the end of our journey it is time to return to the question from which we set out, namely: What is it that characterizes mind as opposed to matter? Or, to state the same question in other terms: How is psychology to be distinguished from physics?
