የአበው የክርክር ጥበብ፡- አለቃ አያሌው እንደ ማሳያ

(በካሣሁን ዓለሙ)
ALEQA AYALEWክርክር የሰው ልጆች የአስተሳሰብ መሞረጃና ማቃኛ ዘዴ ነው፡፡ ይህም ዘዴ አንድን የይገባኛል ጥያቄ በማስረጃ አስደግፎ በምክንያት ማረጋገጥን ወይም መቃወምን ይመለከታል፤ ስለሆነም ክርክር በአንድ በሚያስማማና ተቀባይነት ባለው ማስረጃ ላይ ተመሥርቶ መደምደሚያው ትክክል መሆኑን የሚረጋገጥበት የሙግት ጥበብ ነው፡፡ ክርክር ሦስት ነገሮችን ይፈልጋል፤ እነሱ ካልተሟሉ ክርክር አይኖርም፡-
አንደኛ የሚያከራክረው ነጥብ መቋጫ (መደምደሚያ-Conclusion)፣
ሁለተኛ ነጥቡን የሚያግዝ ማስረጃ መኖር (መንደርደሪ-Premise)፤
ሦስተኛ በትክክልም የመንደርደሪያው ማስረጃ(ዎች) በተጠየቅ መደሚደሚያውን ማገዙ(ዛቸው) (ስምምነት ካለው መንደርደሪያ ላይ ተነሥቶ በአግባቡ መደምደሚያው ላይ መድረሱ- Logical inference) እጅግ ወሳኝ የክርክር ጅማቶች ናቸው፡፡
ስለዚህ ክርክር አንድ የጋራ ስምምነት ያለው ማስረጃ በመነሻነት ከሌለው ወይም መደምደሚያ ካልተሰጠበት ወይም የቀረቡት ማስረጃዎች መደምደሚያውን በአግባቡ ካልደገፉ ንትርክና ንዝንዝ እንጂ ክርክር አይሆንም፡፡ እነዚህን አስፈላጊ ነገሮች ያሟላ ክርክር ግን የሥነ አመንክዮ ክርክር (Logical Argument) ይሆናል፤ የሥነ አመክንዮ ዕውቀትም የሚቃኘው በዚህ አስተሳሰብ ላይ ነው፡፡ Read the rest of this entry »

Arguments and Inference

The Discipline of Logic

Human life is full of decisions, including significant choices about what to believe. Although everyone prefers to believe what is true, we often disagree with each other about what that is in particular instances. It may be that some of our most fundamental convictions in life are acquired by haphazard means rather than by the use of reason, but we all recognize that our beliefs about ourselves and the world often hang together in important ways.

If I believe that whales are mammals and that all mammals are fish, then it would also make sense for me to believe that whales are fish. Even someone who (rightly!) disagreed with my understanding of biological taxonomy could appreciate the consistent, reasonable way in which I used my mistaken beliefs as the foundation upon which to establish a new one. On the other hand, if I decide to believe that Hamlet was Danish because I believe that Hamlet was a character in a play by Shaw and that some Danes are Shavian characters, then even someone who shares my belief in the result could point out that I haven’t actually provided good reasons for accepting its truth.

In general, we can respect the directness of a path even when we don’t accept the points at which it begins and ends. Thus, it is possible to distinguish correct reasoning from incorrect reasoning independently of our agreement on substantive matters. Logic is the discipline that studies this distinction—both by determining the conditions under which the truth of certain beliefs leads naturally to the truth of some other belief, and by drawing attention to the ways in which we may be led to believe something without respect for its truth. This provides no guarantee that we will always arrive at the truth, since the beliefs with which we begin are sometimes in error. But following the principles of correct reasoning does ensure that no additional mistakes creep in during the course of our progress.

In this review of elementary logic, we’ll undertake a broad survey of the major varieties of reasoning that have been examined by logicians of the Western philosophical tradition. We’ll see how certain patterns of thinking do invariably lead from truth to truth while other patterns do not, and we’ll develop the skills of using the former while avoiding the latter. It will be helpful to begin by defining some of the technical terms that describe human reasoning in general. Read the rest of this entry »
