Morality's Missing First Principle
John Stewart Mill
Utilitarianism

Mill critiques both intuitive and inductive schools of ethics for failing to clearly define or reduce their moral precepts to a single, authoritative first principle of obligation.

...he necessity of general laws. They both agree that the morality of an individual action is not a question of direct perception, but of the application of a law to an individual case. They recognise also, to a great extent, the same moral laws; but differ as to their evidence, and the source from which they derive their authority. According to the one opinion, the principles of morals are evident à priori, requiring nothing to command assent, except that the meaning of the terms be understood.
According to the other doctrine, right and wrong, as well as truth and falsehood, are questions of observation and experience. But both hold equally that morality must be deduced from principles; and the intuitive school affirm as strongly as the inductive, that there is a science of morals. Yet they seldom attempt to make out a list of the à priori principles which are to serve as the premises of the science; still more rarely do they make any effort to reduce those various principles to one first principle, or common ground of obligation. They either assume the ordinary precepts of morals as of à priori authority, or they lay down as…
Yet to support their pretensions there ought either to be some one fundamental principle or law, at the root of all morality, or if there be several, there should be a determinate order of precedence among them; and the one principle, or the rule for deciding between the various principles when they conflict, ought to be self-evident. To inquire how far the bad effects of this deficiency have been mitigated in practice, or to what extent the moral beliefs of mankind have been vitiated or made...

Experience's Long Lesson
John Stewart Mill
Utilitarianism

The author refutes the claim that utilitarianism is impractical due to lack of time for calculation, arguing that humanity has used its entire history to learn the consequences of actions through experience.

...m great and unmerited evil, and when the withholding can only be effected by denial. But in order that the exception may not extend itself beyond the need, and may have the least possible effect in weakening reliance on veracity, it ought to be recognized, and, if possible, its limits defined; and if the principle of utility is good for anything, it must be good for weighing these conflicting utilities against one another, and marking out the region within which one or the other preponderates.
Again, defenders of utility often find themselves called upon to reply to such objections as this--that there is not time, previous to action, for calculating and weighing the effects of any line of conduct on the general happiness. This is exactly as if any one were to say that it is impossible to guide our conduct by Christianity, because there is not time, on every occasion on which anything has to be done, to read through the Old and New Testaments. The answer to the objection is, that there has been ample time, namely, the whole past duration of the human species. During all that time mankind have been learning by experience the…
People talk as if the commencement of this course of experience had hitherto been put off, and as if, at the moment when some man feels tempted to meddle with the property or life of another, he had to begin considering for the first time whether murder and theft are injurious to human happiness. Even then I do not think that he would find the question very puzzling; but, at all events, the matter is now done to his hand. It is truly a whimsical supposition, that if mankind were agreed in consi...

Happiness as Sole End
John Stewart Mill
Utilitarianism

Mill argues that because human nature is psychologically driven to desire happiness, it serves as the sole end of human action and the ultimate criterion for morality.

...he pleasure and pain seldom exist separately, but almost always together, the same person feeling pleasure in the degree of virtue attained, and pain in not having attained more. If one of these gave him no pleasure, and the other no pain, he would not love or desire virtue, or would desire it only for the other benefits which it might produce to himself or to persons whom he cared for. We have now, then, an answer to the question, of what sort of proof the principle of utility is susceptible.
If the opinion which I have now stated is psychologically true--if human nature is so constituted as to desire nothing which is not either a part of happiness or a means of happiness, we can have no other proof, and we require no other, that these are the only things desirable. If so, happiness is the sole end of human action, and the promotion of it the test by which to judge of all human conduct; from whence it necessarily follows that it must be the criterion of morality, since a part is included in the whole.
And now to decide whether this is really so; whether mankind do desire nothing for itself but that which is a pleasure to them, or of which the absence is a pain; we have evidently arrived at a question of fact and experience, dependent, like all similar questions, upon evidence. It can only be determined by practised self-consciousness and self-observation, assisted by observation of others. I believe that these sources of evidence, impartially consulted, will declare that desiring a thing an...

Morality's Unresolved War
John Stewart Mill
Utilitarianism

The author laments the lack of progress in philosophy regarding the 'summum bonum,' noting that the foundation of morality remains a subject of intense and unresolved debate despite centuries of inquiry.

...NBERG EBOOK UTILITARIANISM *** UTILITARIANISM BY JOHN STUART MILL REPRINTED FROM 'FRASER'S MAGAZINE' SEVENTH EDITION LONDON LONGMANS, GREEN, AND CO. 1879 CONTENTS. CHAPTER I. GENERAL REMARKS CHAPTER II. WHAT UTILITARIANISM IS CHAPTER III. OF THE ULTIMATE SANCTION OF THE PRINCIPLE OF UTILITY CHAPTER IV. OF WHAT SORT OF PROOF THE PRINCIPLE OF UTILITY IS SUSCEPTIBLE CHAPTER V. OF THE CONNEXION BETWEEN JUSTICE AND UTILITY UTILITARIANISM. CHAPTER I. GENERAL REMARKS.
There are few circumstances among those which make up the present condition of human knowledge, more unlike what might have been expected, or more significant of the backward state in which speculation on the most important subjects still lingers, than the little progress which has been made in the decision of the controversy respecting the criterion of right and wrong. From the dawn of philosophy, the question concerning the summum bonum, or, what is the same thing, concerning the foundation of morality, has been accounted the main problem in speculative thought, has occupied the most gifted intellects, and divided them into sects and schools, carrying on a vigorous warfare against one another.
And after more than two thousand years the same discussions continue, philosophers are still ranged under the same contending banners, and neither thinkers nor mankind at large seem nearer to being unanimous on the subject, than when the youth Socrates listened to the old Protagoras, and asserted (if Plato's dialogue be grounded on a real conversation) the theory of utilitarianism against the popular morality of the so-called sophist. It is true that similar confusion and uncertainty, and in s...

The Need for Subordinate Principles
John Stewart Mill
Utilitarianism

The author defends utilitarianism by arguing that all moral systems require secondary principles derived from human experience, and that the theory should not be blamed for the inherent complexities of human nature.

...Nobody argues that the art of navigation is not founded on astronomy, because sailors cannot wait to calculate the Nautical Almanack. Being rational creatures, they go to sea with it ready calculated; and all rational creatures go out upon the sea of life with their minds made up on the common questions of right and wrong, as well as on many of the far more difficult questions of wise and foolish. And this, as long as foresight is a human quality, it is to be presumed they will continue to do.
Whatever we adopt as the fundamental principle of morality, we require subordinate principles to apply it by: the impossibility of doing without them, being common to all systems, can afford no argument against any one in particular: but gravely to argue as if no such secondary principles could be had, and as if mankind had remained till now, and always must remain, without drawing any general conclusions from the experience of human life, is as high a pitch, I think, as absurdity has ever reached in philosophical controversy. The remainder of the stock arguments against utilitarianism mostly consist in laying to its charge the common…
We are told that an utilitarian will be apt to make his own particular case an exception to moral rules, and, when under temptation, will see an utility in the breach of a rule, greater than he will see in its observance. But is utility the only creed which is able to furnish us with excuses for evil doing, and means of cheating our own conscience? They are afforded in abundance by all doctrines which recognise as a fact in morals the existence of conflicting considerations; which all doctrines...
