"Utilitarianism" by John Stuart Mill


..
Those acts are right and good which produce the greatest happiness for the greatest number of persons.
.
An act derives its moral worth not from its form but from its utility.
.
Although it is the intrinsic worth of pleasure which gives value to acts conductive to pleasure,some pleasures are better than others in quality.
.
The proof of the value of pleasure is that it is desired,and the proof of the claim that some pleasures are better than others is that experienced,rational men prefer some pleasures to others.
.
Justice is the appropriate name for certain social utilities by which the general good is realized.

"Essay in Liberty" by John Stuart Mill,1859


..
An individual's liberty can rightfully be constrained only in order to prevent his doing harm to others.
.
Certain areas of human freedom cannot rightfully be denied :

(for any purpose not involving harm to others).
.
Open expressions of opinions should not be repressed,for if the repressed opinion is true,one loses the opportunity of discovering the truth ;
while if the repressed opinion is false,discussion of its falsity strengthens the opposing truth and makes the grounds of truth evident ;
furthermore,the truth may be divided between the prevailing opinion and the repressed one,and by allowing expression of both,one makes recognition of the whole truth possible.

"A System of Logic" by John Stuart Mill,1843


..
Terms denote only particulars,and the only particulars we can speak of significantly are those we are acquainted with.
.
The syllogism is not a form of proof which allows inference to particular statements from general statements,but a form of argument which relates inductive conclusions to present inductive generalizations.
.
Mathematical propositions are synthetic and empirical (not analytic and verbal),and the only necessity attaching to them is a psychological necessity.
.
By the methods of agreement,difference,residues,and concomitant variation inductive generalizations are possible.
.
Inductive inference is based on the principle of the uniformity of nature
-which is itself a principle established by inductive argument.
