Connecting tradition and progress

 




Practical Sciences

The fundamental limitations of the concept of applied sciences are highlighted. As an alternative, reference is made to the practical tradition that has existed since antiquity. Empirical (descriptive, explanatory or prognostic) sciences and practical (normative, pragmatic or technical) sciences are complementary.

Most publications about practical sciences are currently available in German only:
praktische-wissenschaften.de.  

In an article I discussed the need for a practical methodology alongside a descriptive and explanatory one. The charts below offer a concise summary of the argument.

Seitenanfang Chart 1: The Ten Levels of Scientific Methodology
1.1 Philosophical foundations:

Tasks and limits, axiological, epistemic, methodological and ontological assumptions, conditions or criteria as well as ideals and proper-ties of scientific research
1.1.1 Philosophical level (1) A. Tasks and objectives of scientific research
B. Limits of scientific research
C. Axiological, epistemic, methodological and
ontological assumptions of (political) scientific
research

Seitenanfang Chart 2: Three Traditions and Ten Levels of Political Methodology
Scientific methodologies and types of science I. Descriptive tradition:
empirical-descriptive methodology (sciences)
II. Explanatory-Prognostic Tradition:
empirical-explanative and empirical-prognostic methodology (sciences)
III. Practical tradition:
practical (normative, pragmatic and technical) methodology (sciences)
1. Axiological and ontological level Descriptions:
description of (visible) phenomena, interpretation of symbols (text, image, audio and video), especially by means of language
Explanations and predictions:
recognition and explanation of invisible causalities using especially
logic and mathematics
Valuations:
world change, Design of the Political Order,
practical (normative, pragmatic and technical) standards (norms) and regulations using logic, language and mathematics
2. Epistemical level Empirical-descriptive
knowledge
 
Empirical-explanatory and empirical-predictive knowledge Practical (normative, pragmatic and technical) knowledge
3. Level of ideals and properties

 

Ideal of truth

Predicates: true or false

Ideal of rightness (ethics): right/wrong
Ideal of justice (politics): just/unjust
Ideal of phronesis (Klugheit): wise/unwise
Ideal of efficacy: effective/ineffective
4. Concept level Qualitative, interpretative
or classificatory concepts

Quantitative, mathematical
or metric concepts
Practical (normative, pragmatic and technical) concepts
5. Proposition level Descriptive propositions 
Explanatory and
predictive propositions
Norms, i.e. justice standards, pragmatic and technical rules
6. Theory level Empirical theories consist of systems of propositions, including propositions about standards and rules. Practical theories consist of regulations, i.e. systems of empirical statements and
practical standards and regulations.
7. Logic level

Formal inference and inference rules related to scientific concepts and scientific sentences
Truth-apt logic:

Propositional
logic: It is the case, that [...]
Predicate logic: F "is a human".

Modal logic, e.g. alethic modal logic:
It is necessary/impossible/possible/contingent that [...]

Epistemic logic: It is known/is epistemically necessary/is inconsistent that […]

Doxastic logic: It is believed/considered impossible/conceivable that [...]

Tense logic: It was/will be/always will be/always was the case that [...]

Deontic logic (is-ought, Sein-Sollen):
It ought to be/it is forbidden/permitted/indifferent that [...]

Unlike classical logic, these are not truth-apt (Jørgensen's dilemma).

Logic of Norms (act-ought, Tun-Sollen, not is-ought, Sein-Sollen), logic of imperatives, interrogative logic, legal logic, logic of implementation (Durchführungslogik).


Efficacy and rightness, Prima-facie property of ethical norms and political maxims of action.
Conflicts of justice standards and mediation of justice standards.

8. Argumentation level

Argumentation inside scientific theories or logical structure of scientific arguments, logic of scientific research

 

 

 


Analytical, dialectical, empirical, evolutionary
or hermeneutic means of argumentation
Practical  (normative, pragmatic and technical) argumentation
Explaining-understanding-debate
thought of as complementary
 

 

 

Practical, substantive argumentation:
practical syllogism and
pragmatic syllogism

Understanding Explaining
Abductive, inductive,
substantial, warrant-using, tentative, formally invalid, epagogical
argumentation:
Hegelian dialectics,
hermeneutic circle
 
Deductive, analytical,
warrant-establishing,
conclusive, formally valid argumentation:
deductive-nomological
model (or HO scheme),
evolutionary explanatory model
Aristotelian topic (dialectics)

9. Methods level
with reference to political science.


Scientific investigation of facts and judgements,
generation and evaluation of facts.

Empirical-descriptive methods
Empirical-explanatory and empirical-predictive methods practical (normative, pragmatic and technical) methods
Qualitative methods:
content analysis,
document analysis,
participatory observation
Quantitative methods:
quantitative data collection,
correlation and
regression analyses
Arguing, discourse,
deliberation, mediation, synopsis,
categorical imperative,
evaluation, implementation planning,
technology assessment (TA)
Triangulation: The application quantitative and qualitative methods on a phenomenon.
10. Methodical
approaches level

with reference to political science

Generation and evaluation of
theories
Approaches with empirical and practical elements
Socio-technological, synoptic, practical-normative, critical-dialectical, empirical-normative, argumentative and pragmatic approach, rational choice approach, advocacy coalition approach, governance approaches, actor-centered approaches (decision arenas, networks, exchange and negotiation systems, regimes)
Empirical approaches Practical approaches
Historical, institutional
and structuralist approach,
narratives, frames, discourses
Behavioural,
functional and
quantitative approach
Participatory policy approach,
decisionist, synoptic,
normative, pragmatic and
technical approach
