“Educazione e criminalità” is the title of the third chapter. The human brain is an organic mechanism, similar (but with numerous exceptions) to an inorganic mechanism in this, that it is subject to the great law of the conservation of energy, which manifests itself, among other ways, in inertia. From which it comes that man at all times has had an irresistible tendency to make use of a general principle as a basis for his logical structures. Without this he would always be forced to build each new structure from the ground up, which would involve the waste of too much cerebral energy. Opposed to this law is another which teaches us that life is impossible in a state of absolute repose, but that it requires a perpetual changing of the organic and physio-psychic materials. Hence it comes that eternal and absolute truths change at different epochs, and that they seem stable only when compared with the secondary truths, which are subject to the fashions of the time.

According to the author, then, there are truths that are more general and nearly inalterable, but there are others which, though general also, are more secondary, only retain their force during several generations, and end by being changed. Such, for example, are the views concerning human life, formulated by the great thinkers, then accepted by the majority, and finally supplanted by other truths. This is why science makes progress by dogmas. It is modern science that has made the great step in recognizing that these dogmas are relative and alterable.

Against this reasoning two objections can be alleged. First, that Spencer has given the name “hypothesis” to his doctrine of evolution, while Professor Ferri calls it a dogma. The author on the other hand thinks that his opinions and those of Spencer are exactly alike, [[119]]for he calls the doctrine in question a relative and alterable dogma, and Spencer says of it: what I have given is an hypothesis; but so long as there is nothing better, that will explain a greater number of facts, I have a right to consider it as the image of the knowable truth, until the contrary is proved. In the second place, it may be asked: “Does man always oscillate between truth and error; will he never know an absolute and eternal truth?” According to Professor Ferri the answer to this question is not difficult. The origin as well as the aim of faith is the effort to give to men a relatively stable support, which they cannot find elsewhere. All discussion with the adherents of a theological opinion is excluded; and as for the others, ought they not to recognize that the life of human thought is just the constant proof of the continual modification of the so-called eternal verities?

After this introduction the author enters upon the subject itself. At the beginning of the 19th century the dogma was dominant, that instruction was the panacea for all crimes. Later many of the publicists, including the socialists, advanced the opinion that the true remedy for criminality was education. Just as the first theory was incorrect, Professor Ferri would show that the second is equally so.

The question is, can education lead man to good or to evil; and if it can, how far can it lead him? The scientific pedagogues have not treated this question, as far as the author knows. Without furnishing proofs the socialists admit that education can modify man in many respects. Owen, for example, says: “every child may be brought up to have in his later life only good habits, or bad, or a mixture of the two, according to his education.”

It is necessary to distinguish three kinds of education—physical, intellectual, and moral. First, a general observation applicable to all kinds of education. In his physical, intellectual, and moral make-up, each individual is the product of a countless number of ancestors, to whom he is bound by unchangeable laws of heredity. From this it is clear that the power of education, which acts only during a limited number of years, is small compared to that of the influences to which a man’s ancestors have been subjected for thousands of years. The question becomes, then: “what are the limits of such modification?” Further it is necessary to determine just how far this modification is due to education, and how far to environment. For education, properly so called, i.e. the direct and methodical influence of the educator upon his pupil, differs in many respects from that of the physical and social environment. This is why the author treats this latter in a special chapter, and limits himself now [[120]]to education alone. The question is therefore reduced to this: “how far can a man (the educator) modify the constitution of another man (the pupil)?”

One more observation should precede the study of the question, namely that a force, or a complexus of forces, can be influenced only by other homogeneous forces. Now when we examine how far physical or biological education can make its influence felt, we see that this influence may be very great, though naturally limited, in proportion to the knowledge we have of the structure and functioning of the organs which it is attempted to modify. As to intellectual education, the results are much less, since the knowledge of the organs involved is much smaller. As to moral education, the following question is one to which pedagogues have given little attention: “how far do morality or immorality, good or bad character, depend upon the education received at home and in school?”

Spencer lays down the fundamental rule that the moral conduct of man can be studied scientifically only on condition of being considered as forming part of the conduct in general, and also of the activity in general, of all living beings. Sergi is of the same opinion. And this is correct, Professor Ferri thinks, if, as these two authors do, one studies the conduct and character of man in their constituent elements, in their genesis and development, without taking into consideration the variability of the character, and consequently of the conduct, of man because of his education. In our case, in studying the constituent elements, the genesis, the development, and the variability of the moral part of the character and conduct of man, it is necessary to separate these parts, and to limit ourselves to a special study of one of them.

All psychologists are agreed that the moral conduct of a man (including criminal conduct) although having naturally a certain relationship with his muscular and intellectual condition, depends directly and intimately upon the condition of his feelings, emotions, and passions in their moral aspect. Hence it is clear that the problem is: “how far can these feelings be modified by education?”

Let us first of all note that the expression, “a man of good (or bad) birth”, does not imply that there are persons who are totally good or totally bad, for these two qualities always appear in combination. It only indicates whether the good or the bad qualities predominate.
