  • AHSGS COLLOQUIUM FOR GRADUATE STUDENT 2015*

  • WHAT IS A PHD/DBA?

    A phd/DBA is not merely a vague title but actually means what it implies: it is an award to an expert who has proven their scientific worth and not to someone who stayed in a tolerant group for long enough *

  • WHAT IS RESEARCH ?RE-SEARCH: THE ART OF DIS-COVERYOrganized Study:Methodical Investigation Into A Subject In Order To Discover Facts, To Establish Or Revise A Theory, Or To Develop A Plan Of Action Based On The Facts Discovered

    *

  • PHILOSOPHYPhilosophy derives from A combination of the greek words philos meaning love and sophia meaning wisdom. What philosophy is, or should be, is itself A philosophical question that philosophers have understood and treated differently through the ages.

    Philosophy can mean the academic exploration of various questions raised by philosophers; or to the collective works of major philosophers; it can also mean a certain critical, creative way of thinking. *

  • EPISTEMOLOGYTheories of knowledge or studies of knowledgeBranch of philosophy that asks whether we know things and, if so, howThe study of source, nature, varieties and limitations of knowledgeIt attempts to answer the basic questionTrue (adequate) vs false (inadequate) knowledgeThe above Q lead to sc.Fic methodology: to improve existing theories or models*

  • SOME TYPICAL PROBLEMS CLASSICAL EPISTEMOLOGY ADDRESSESWhat can we knowHow do we knowWhat, if anything, does the subject contribute to his knowledgeWhat is truthHow can we recognize truthWhat is probable knowledge as opposed to certain knowledgeIs there a priori knowledge, and if so whatHow action and language are related to knowledgeWhat is the status of concepts and propositions

  • *KNOWLEDGE TRADITION

    The history of knowledge and science not begins from West but from East.

    The most important area are Egypt and Mesopotamia (Babylon) which located at Nil Valley and Tigris-Euphrates River Valley

    These area are so special because of the knowledge heritage and development of science and technology

  • ESTERN TRADITIONEGYPT & MESAPOTAMIAARCHEOLOGY, MATHEMATIC, GEOMETRY, MEDICINE, ARCHITECTUREINDIAMATHEMATIC, MEDICINE, ASTRONOMYCHINANATURAL SCIENCE*

  • * WHAT ARE THE SIGNIFICANCE OF KNOWLEDGE CIVILIZATION IN EGYPT AND BABYLON?Knowledge tradition or civilization begins from East not WestHolistic knowledge activities was parallel with religious activities. In other word, knowledge scholar at the same time also religious scholar.The founder of knowledge in Egypt and Babylon were the prophet and messenger of God. In Islamic tradition, Adam not only the first man, but also pioneer of all knowledge. He taught his children with technical knowledge, especially Syith.Syith was the teacher of Idris, who born in Babylon. He was the founder of geometry, astronomy, medicine, and continued by Daniel.

  • *

    Integrated Knowledge CivilizationThe development of knowledge that started from East had flow to West. But the development was just for a few decades, before conquered back by East. Along the middle age (10 centuries), Islamic world was in the knowledge brightness, but in the West was in the Dark Ages. Islamic knowledge civilization are Ilmu Naqliah or Syariyyah (revealed science) and Ilmu Aqliyah (rational science). Ilmu Naqliah : Ulum Quran, Ulum Hadith, Ilmu Tauhid, Ilmu Fiqh and Ilmu Akhlak, the history of prophet, and Arabic Language. Ilmu Aqliyah: philosophy, history, geography, science, mathematic, and astronomy.Famous scholars: al-Khindi, al-Farabi, Ibn Sina, Ibn Tufail Ibn Rusyd, al Khawarizmi, al Ghazali.

  • REALITY OF KNOWLEDGE (CONTINUED)AT LEAST 3 WELL ESTABLISHED PARADIGMS IN THE DEVELOPMENT OF SCIENCE:

    CLASSICAL PARADIGM: KNOWLEDGE-CURIOSITY-DRIVEN.2ND PARADIGM: TECHNOLOGY-MILITARY-POWER-DRIVEN.3RD PARADIGM: MARKET-WEALTH-DRIVEN PARADIGM.

    VALUE & RESPONSIBILITY*

  • ONTOLOGY DEFINITIONSConcerned with the study of being, of reality in its most fundamental and comprehensive forms.

    The theory of objects and their ties. The unfolding of ontology provides criteria for distinguishing various types of objects (concrete and abstract, existent and non-existent, real and ideal, independent and dependent) and their ties (relations, dependences and predication).

    *Ref: www.formalontology.it/Ref: www.atf.org.au/papers/glossary.asp

  • TYPES OF ONTOLOGYThere are four different types of ontology:

    Domain ontologies, representing a target domain, as engineering, medicine etc.Generic or common sense ontologies, capturing general knowledge about time. Space, events, etc.Method ontologies, describing specific task, as diagnosis.Metadata ontologies, describing the content of on-line information sources.*

  • EPISTEMOLOGYTHEORY & SOURCE OF KNOWLEDGEIn epistemology a common definition of knowledge is that it consist of justified true belief. For most philosophical history, knowledge was taken to mean a belief that was justified as true to an absolute certainty. Any less justified beliefs were called mere probable opinion. To be a knowledge, a belief has to have some positive epistemic feature; it cant be arbitrary or random or irrational. (Source:http://en.Wikipedia.Org/wiki/knowledge)*

  • RATIONALISMThe human reason, or understanding, is the sole source and final test of all truth.Renes Descartes (1596-1650) using mathematical and geometrical analytical method.

    *

  • EMPIRICISMIs the philosophical doctrine that all human knowledge comes at first from sense and experience. Empiricism denies that human have innate ideas that anything is knowable prior to any experience.

    *

  • EMPIRICISM*Classical Empiricism : Aristotle argued that all form of knowing come from induction. Modern Empiricism :All knowledge must be attained by our consciousness through internal and external sensations. (David Hume, John Locke and George Berkeley)Radical Empiricism : All human knowledge is purely empirical. (William James)Nave Empiricism : Our ideas and theories need to be tested against reality and not be affected by preconceived notions.Constructive Empiricism : According to this view of science coined by Bas Van Fraassen (The Scientific Image, 1980), we should only ask that theories accurately describe observable parts of the world. Theories that meet these requirements are considered empirically adequate. If a theory become established, it should be accepted. What that means is the theory is believed to be empirically accurate, use to solve further problem, and use to extend or refine the theory.

  • CONFORMISMTerm used to describe a state of orthodoxy, the suspension of actions or opinions in favor of obedience to the mandate or conventions of ones peer group. The old saying expresses this well : when in rome, do as the roman do. By definition, conformism present the antithesis both of creativity and of innovative leadership and hence oppose change or progress.*

  • INTUITISMImmediate apprehension by mind without reasoning. The belief that primary truths and principles especially of ethics and metaphysics are known directly by intuition.The knowing of something without prior knowledge or the use of reason. All stands revealed the hearts, the motives, the causes all events. Able to sense the invisible and the impalatable. Prophets are often intuitive. Acquire through spiritual intelligence (SQ)

    *

  • REVELATIONThe kind of knowledge that is given by god to man through direct revelation. Unveils the mystery of being and existence and reveals the true relationship between mans self and his lord, and since for man such knowledge pertains to the ultimate purpose of knowing, it follows that knowledge of its prerequisites become the basis and essential foundation for the knowledge of the second kind (knowledge of science). (Source : SYED MUHAMMAD NAQUIB AL-ATTAS)*

  • * TYPES OF METHODOLOGYLogical Thinking -- The Source of Methodology

  • * TYPES OF METHODOLOGYOverview of Methodology Types of Methodology Deductive Inductive Hypothetical Deductive RabbaniObservationsGeneral Understanding/ ConclusionObserved phenomenonConclusion/ Understandingfrom specific observationConclusion/ UnderstandingBased on general rules/ understanding

  • *DEDUCTIVE METHODOLOGY WHAT IS IT? Definition: Make an inference to explain specific observed phenomenon based on existing general understanding, rules or knowledge Originated from the Latin words de ( From) and decere (Lead towards) Syllogism (Al-qias) Introduced by Aristotle (384~322BC) Classic logical KnowledgeGeneral Understanding/ ConclusionObserved phenomenonConclusion/ UnderstandingBased on general rules/ understanding

  • *DEDUCTIVE METHODOLOGY PROCESS Move from General understanding (postulate & Axiom) as Premise Specifics phenomenon Postulate Something that believe to be true but not proven (without empirical study or observation) Axiom Formal rule or principle that generally to be true, dominated in Mathematics Minor Premise + Major Premise Conclusion

    Example: (Muqaddimah al-Sughra) (Muqaddimah al Kubra) (Natijah)All vegetables is nutritiousNutrition is good for health All Vegetables is good for health (Muqaddimah al-Sughra (Muqaddimah al Kubra)(Natijah)+=

  • * INDUCTIVE METHODOLOGY - DEFINITION Definition: Generalizing a knowledge, understanding, conclusion from the understanding of specifics observation to a general rules or knowledge with the elements of probability Modern Logical Knowledge based on empirical study Types of Induction: Completed(Al-Istiqra Tamn)& Limited (al-Istiqra Naqis)

  • FALSIFIABILITY AS A CRITERION FOR THEORIES Theories shown to be false through observation and experiment. Example: proton cars never breakdown or ice will not melt if room temperature is 0 celciusTo be part of science, any hypothesis must be falsifiable; logically possible observation of any hypothesisThus statements which is vaguely form and is not falsifiable is not scientific. Example: proton savvy may be better than myvi but it may not be as good.

    *

  • DEGREE OF FALSIFIABILITY, CLARITY AND PRECISIONAny theories which can be proven in terms of falsifiability is a good scientific law. Example, newtons theory proven to be more resistant to falsifying than Keplers Theory. Science progresses by trial and error; theories which were not falsified yet meant they are the currently most accurate ones and not guaranteed to be true forever.Thus, any theories should be clearly stated and not vague.*

  • FALSIFICATIONISM AND PROGRESSScience starts from problems. Hypotheses are formed as solution to problems. Falsificationist seeks ways to continue rigorous tests to falsify a certain theory after which a stronger theory emerges. Aristotles theory being taken over by newtons theory. Newtons theory was able to account for more issues which Aristotles theories did not mention. This was followed by Einsteins Theory which proved to be a challenge to falsify for current modern physicists. There is no truth, only the current most correct answer.

    *

  • LIMITATIONS OF FALSIFICATIONISMTheory-dependence of observation and the fallibility of falsificationsTheory acceptance is always tentative (for now)Theory rejection is decisive (forever) Note that observation might be wrong! Thus many instances whereby rejections of observation statements and the retention of the theories they clash *

  • FALSIFICATIONISM INADEQUATE ON HISTORIAL GROUNDSTheories may have been rejected due to historical grounds. Example: newtons gravitational theory was falsified by observation of the moons orbit. Only after 50 years that this is deflected to other causes than newtons theory.

    *

  • *Hypothetico-deductivePhilosopher Karl Popper suggested that it is impossible to prove a scientific theory true by means of induction, because no amount of evidence assures us that contrary evidence will not be found. Instead, Karl Popper proposed that proper science is accomplished by deduction. Deduction involves the process of falsification. Falsification is a particular specialized aspect of hypothesis testing. It involves stating some output from theory in specific and then finding contrary cases using experiments or observations. The methodology proposed by Popper is commonly known as the hypothetico -deductive method.Popper's version of scientific method first begins with the postulation of a hypothesis.A hypothesis is an educated guess or a theory that explains some phenomenon. The researcher then tries to prove or test this scientific theory false through prediction or experimentation

  • AXIOLOGY- THE VALUEOF TRUTHIn everyday life, people distinguish between truth and falsehood as a matter of survival. People who are unable to recognize lies, mistakes or inaccuracies, at least most of the time, suffer greatly.The philosophical problem of truth has been described as the search for the nature of truth. It applied to a statement or belief.

    *

  • THEORIES ABOUT TRUTHCorrespondence theory of truth : truth is correspondence with objective reality. Thus, a sentence is said to be true just in case it express a state of affair in the world. Eg. Snow is white is true.The coherence theory : truth is coherence with some specified set of sentences or, more often, of beliefs. For example, one of a persons belief is true just in case it is coherent with all or most of her other beliefs. Pragmatic theory of truth : based on the foundation of the principle of evolutionism. An idea can only be considered true if posses practical value or vital benefits. Pragmatism believed absolute truth do not exist (Charles Sanders Pierce, William James). Nature of truth statement by working hypothesis, focus on similarities and differences.

  • TYPE OF TRUTHSUBJECTIVE VS OBJECTIVESUBJECTIVE TRUTH Are those with which we are most intimately acquainted. Metaphysical subjectivism holds that all we have are such truths. That is, that all we can know about are one way or another, our own subjective experiences. This view does not reject realism. But at least it claim that we cannot have direct knowledge of the real world.OBJECTIVE TRUTH Are suppose to be one way to be independent of our subjective beliefs and tastes. Such truth would subsist not in the mind but in the external object.*

  • RELATIVE VS ABSOLUTERelative truths are statements or propositions that are true only relative to some standard or convention or point-of-view. Everyone agrees that the truth or falsify of some statements is relative: the fork is to the left of the spoon depends on where one stands. Relativism entails that what is true varies across cultures and eras.Absolute truths are statement or propositions that are taken to be true for all cultures and eras. Example: for muslim, Allah is great expression an absolute truth; for economist, that the law of supply and demand determine the value of any consumable in the market economy is true in all situations.Absolutism in particular domain of thought is the view that all statements in that domain are either absolute true or absolute false: none is true for some cultures or eras while false for other cultures or eras. Example abortion is wrong or charity is good.*

  • THE CONCEPT OF DOUBT FROM ISLAM VIEWPOINTThe doubt (shakk), conjecture and guess disputation and contention, inclination of mind or soul towards natural desire (hawa), are all generally considered blameworthy-the more so when applied to an masquerading as knowledge. We must take note of the significance that, in the case of western culture and civilisation, and with reference to sociology of knowledge, the west defined knowledge in terms of the effort of science as control of nature and society. (Syed Naquib Al-Attas) There are situations and issues which do not require thinking. One does not need to conduct lengthy experiment and engage in extensive study to prove something that is plainly obvious from every day experience. According to Al-Ghazali, doubt is the first stage of certainty (yaqin). His concept of doubt is not based on scepticism but more on methodological. When the doubt is clear, certainty will emerge. *
