See also:CONVERSION (See also:Lat. conversio, from convertere, to turn or ,See also:change) , ageneral See also:term for the operation of converting, changing, or transposing; used technically in See also:special senses in See also:logic, See also:theology and See also:law . r . In logic, See also:conversion is one of three See also:chief methods of immediate inference by which a conclusion is obtained directly from a single premise without the intervention of another premise or See also:middle term . A proposition is said to be "converted" when the subject and the predicate See also:change. places; the See also:original proposition is the "convertend," the new one the "converse." The chief See also:rule governing conversion is that no term which was not distributed" in the convertend may be distributed in the See also:con-See also:verse; nor may the quality of the proposition (affirmative or negative) be changed . It follows that of the four possible forms 1 A term is said to be." distributed " when it is taken universally: in the proposition " men are mortal " (meaning . " all men ") the term " men " is " distributed " while " mortal " is undistributed, because there are mortal beings which are not men . of propositions A, E, I and 0 (see See also:article A), E and I can be converted simply . If no A is B (E), it follows that no B is A; if some A is B, it follows that some B is A . This See also:form of con-version is called See also:Simple Conversion; E propositions convert into E, and I into I . On the other See also:hand, A cannot be converted simply . If all men are mortal, the most that can follow by conversion is that some mortals are men . This is called Con-version by See also:Limitation or Per Accidens . Only if it be known from See also:external or non-logical See also:sources that the predicate also is distributed can there be simple conversion of a universal affirmative . Neither of these forms of conversion can be applied to the particular negative proposition 0, which has to be dealt with under a secondary See also:system of conversion, as follows . The terminology by which these secondary processes are described is not altogether satisfactory, and logicians are not agreed as to the application of the terms . The following system is perhaps the most commonly used . We have seen that the converse of "all A is B" is "some B is A"; we can, in addition, derive from it another, though purely formal, proposition "no A is not-B"; i.e. an E propo ition . This See also:process is called Obversion, Permutation or Immediate Inference by Privative Conception; it is applicable to every proposition including O . A further process, known as Contraposition or Conversion by Negation, consists of conversion following on obversion . Thus from "all A is B," we get " no not-B is A." In the See also:case of the 0 proposition we get (by obversion) "some A is not-B " and then (by conversion) "some not-B is A" (i.e. an I proposition) . In the case of the I proposition the contrapositive is impossible, as infringing the See also:main rule of conversion . Another term, See also:Inversion, has been used by some logicians for a still more complicated process by the alternative use of conversion and obversion, which is applicable to A and E, and results in obtaining a proposition concerning the contradictory of the original subject; thus "all A is B becomes "some not-A is not B." Considerable discussion has centred on the problem as to whether the process of conversion can properly be regarded as inference . The essence of inference is that the conclusion should embody knowledge which is not in the premise or premises, and many logicians have contended that no fact is stated in the converse which was not in the convertend, or, in other words, that conversion is merely a transformation or verbal change of the same statement . Hence the term Eductions and See also:Equivalent Propositional Forms have been given to converse proposi tions .
It is clear, for instance, that if the universal affirmative is taken connotatively as a scientific law, and not historically, no real inference is achieved by stating as another scientific fact its converse, the particular affirmative
.
Moreover, even if the convertend is stated as an historic fact, though there is acquired a certain new significance, it may well be argued that the inference is not immediate but syllogistic

In theology, conversion (the equivalent of the Gr. o rOOew, See also:bran-00ov) is originally the acceptation of See also:Christianity by heathens
.
It is also used generally for a change from one See also:religion to another, or in a narrower sense for a See also:complete change of attitude towards See also:God, involving a deeper conviction of the ultimate religious and moral truths
.
Considerable difference of See also:opinion has always existed, and still exists, within the See also:Christian See also: The precise connexion between conversion and repentance is again a vexed question . How far and in what sense does man take an active See also:part in his own conversion ? To this it is ,frequently answered that while the initial See also:stage of conversion is and can be the See also:work of the See also:Holy Spirit alone, it lies with man to make it complete by accepting the proffered grace in repentance and faith (cf . Acts vii . 51, "Ye stiffnecked and uncircumcised in See also:heart and ears, ye do always resist the Holy See also:Ghost") . A man may of his own See also:free will avoid those surroundings which predispose him to such "resistance." The view that man cannot convert himself is clearly stated in Article X. by the Church of See also:England . " The See also:condition of man after the fall of See also:Adam is such that he cannot turn (sese convertere) and prepare himself by his. own natural strength and See also:good See also:works, to faith, and calling upon God: where-fore we have no See also:power to do good works pleasant and acceptable to God, without the grace of God by See also:Christ preventing us that we may have a good will, and working with us, when we have that good will." Further problems are connected with the possibility of repeated conversions of the same man, the See also:necessity, of a single strongly marked conversion completed in, a single process, the significance of sudden conversion of persons in a highly emotional See also:state, such as has been See also:common in revivalist meetings, especially in See also:Wales and the See also:United States of See also:America . Conversions of the last See also:kind have followed frequently on striking See also:physical phenomena, perceived in many cases only by the convert himself, such as a sudden See also:bright See also:light or a See also:noise like a clap of See also:thunder.l In all cases of conversion, however, the criterion of its, validity is generally taken to be the resultant change of a man's See also:character as manifested in his mode of life and thought, in the abstention from See also:sin, and in devotion to good works . (X.) 3 . In See also:English law, conversion is the unauthorized exercise of dominion by one person over the See also:property (other than See also:money, or chattels real) of another, in a manner inconsistent with his rights of See also:possession, or the unauthorized See also:assumption by another of the See also:powers of the true owner of goods . The See also:history and exact See also:definition of this form of actionable' wrong have occupied the See also:attention of many learned writers, and the incidents of. actions to assert the rights of the true owner form a considerable part of See also:treatises on the rules and forms of See also:civil See also:pleading . There are many ways in which the wrong may be committed .
In some cases the exercise of the dominion may amount to an See also:act of trespass or to a See also:crime, e.g. where the taking amounts .to See also:larceny, or fraudulent See also:appropriation by a bailee or See also:agent en-trusted with the property of another (Larceny Acts of 1861 and 1901)
.
But in such cases, except where money is taken, the civil remedy of the owner is by See also:action for conversion or detention of the property, subject in the case of larceny to the rule that criminal See also:prosecution should precede restitution by the taker
.
The remedy in use in these cases used to be by what was called an action on the case for See also:trover and conversion, the See also:plaintiff putting aside all suggestions of trespass and of crime, and resting his case on the fiction that the See also:defendant had found and used goods not his own
.
The fictitious averment of loss was abolished in 1852, and under the See also:present See also:procedure, in which the old forms of action are not in use, the remedy is by a claim (still usually called conversion) for wrongfully depriving the true owner of See also:personal property of its use by some specified act inconsistent with his dominion over it, usually by dealing with the property in a manner inconsistent with the owner's rights
.
Originally, the action of trover and conversion was limited to goods and chattels, but it is now accepted as applying to valuable securities, such as cheques and bills of See also:exchange
.
The gist of the action is in the unauthorized dealing, for however See also:short a See also:time and for however limited a purpose, with the personal property of another
.
Even refusal to deliver up to the owner is sufficient to prove conversion, though it is often
1 Numerous instances, See also:drawn from other religions besides Christianity, are given in See also:Professor See also: 77–85; Larceny Act, 1901) . The law of See also:Ireland, of most See also:British possessions, and of the United States, follows that of England as to the civil or criminal remedies for conversion . The term "conversion" is also used in Englishlaw with reference to the rule of courts of See also:equity which, in certain cases (following the See also:maxim of treating as done what ought to have been done), treats as converted into personalty See also:land which has been directed so to be converted by a will, See also:contract or See also:settlement, or as converted into land personalty which has been by such See also:instrument directed to be applied for See also:purchase of realty . The rule is also applied where a vendor of land See also:dies between the making of the contract of See also:sale and its completion by See also:conveyance of the land . The importance of the rule lies in the different destination of realty and personalty under the See also:laws See also:relating to See also:inheritance and See also:succession .
