4.1. Introduction

A Theory emerges when explanation is set forth systematically, usually from language, or by means of other signs and annotation.

4.1. Introduction

What is theoria?

• The “active contemplation” of an object, rather than the passive reception of external effects.”

What is theory?

Several definitions depending on the discipline. • In the natural sciences it is a removed and systematic accounting of an object where exact prediction is very high; i.e. where the relationship between several factors can be demonstrated to cause a result that can be predicted over and over again. If it cannot be demonstrated then it is determined to be a false theory.

What is theory?

• In the human sciences it is not based on exact prediction (as much), but rather on statistical probabilities that can generalize on behavior or on a detailed “thick description” of a particular social-cultural context.

What is theory? • In the fine arts it is based on systematic philosophical constructions.

A scientific theory: Archimedes' Buoyancy Principle “EUREKA!” • After he discovered his principle of buoyancy, the ancient Greek scholar Archimedes allegedly yelled out "Eureka!" and ran naked through the city of Syracuse. The story goes that Archimedes made his great breakthrough when he noticed the water rise as he got into the tub.

• According to Archimedes' buoyancy principle, the force acting on (buoying) a submerged or partially submerged object equals the weight of the liquid that the object displaces. This sort of principle has an immense range of applications and is essential to calculations of density, as well as designing submarines and other oceangoing vessels.

• Explains the past, the present and predicts the future!

A scientific theory: Law of Gravitation • more than 300 years ago Sir Isaac Newton proposed a revolutionary idea: that any two objects, no matter their mass, exert gravitational force toward one another. This law is represented by an equation that many high schoolers encounter in physics class. It goes as follows: F = G × [(m1m2)/r²] •

F is the gravitational force between the two objects, measured in Newtons. m1 and m2 are the masses of the two objects, while r is the distance between them. G is the gravitational constant.

• The benefit of the universal law of gravitation is that it allows us to calculate the gravitational pull between any two objects. This ability is especially useful when scientists are planning to put a satellite in orbit or charting the course of the moon.

• Explains the past, the present and predicts the future!

A scientific theory: E=mc

2

• E represents energy, m represents mass, and c² is the square of the speed of light (2.9 x 10^8 meters per second!).

• A tiny amount of mass when multiplied by such a huge number (C) yields an incredible amount of energy. Releasing that energy can do everything from power cities (a nuclear power plant) to destroy them (a nuclear bomb).

• Predicts the future!

A scientific theory: Big Bang Theory • The big bang theory postulates that the universe began almost 14 billion years ago with a massive expansion event. At the time, the universe was confined to a single point, encompassing all of the universe's matter. That original movement continues today, as the universe keeps expanding outward. • Explains the past, the present and predicts the future!

A scientific theory: PLACEBO EFFECT • If you're given a pill and told it'll cure your headache, and your condition improves even though the pill contains nothing but chalk, you have experienced the placebo effect. If you believe in it strongly enough, almost anything can have a placebo effect. • Scientific tests under controlled conditions have shown that placebo effects can be enhanced by giving people bigger pills, by giving them pink pills rather than white ones, and by the perceived seniority of the doctor who's prescribing the pill. • Predicts the future!

If you believe in it strongly enough, almost anything can have the placebo effect

A scientific theory: MEMETICS • Whenever we copy habits, skills, stories or any kind of information from person to person, we're dealing in memes. The term was coined by Richard Dawkins to describe 'cultural replicators' that copy and transmit biological information. Humans copy memes, including ideas and skills, through imitation and teaching; but they get changed, accidentally or on purpose, so that culture evolves. This echoes the way species evolve as genes mutate. Like genes, some memes are successful, while others aren't. It's obvious why some memes spread - they're useful, or aesthetically pleasing, like melodies. But some spread even though they confer no clear benefit - things like computer viruses. • Predicts the future!

An Architecture Theory: Vitruvius • "De architectura libri decem" (Ten Books on Architecture), the oldest treatise on architecture to survive in its entirety from pre-Christian times.

• Vitruvius' work is not simply a unique source off information about the architecture of antiquity and its principles, but has become the foundation for all writings on architectural theory since the Renaissance.

• The three fundamental laws that Architecture must obey, in order to be so considered: firmitas, utilitas, venustas, translated in the 17th century by Sir Henry Wotton into the English slogan firmness, commodity and delight (meaning structural adequacy, functional adequacy, and beauty).

• What architecture is!

Born: Rome ca. 80 B.C. Died: Rome, ca. 20 B.C.

Firmitas firmness

Utilitas

Venustas

An Architecture Theory: Le Corbusier • The New Spirit of the 20th-century: The ideal house as “a machine for living. Based on engineering achievements in bridge building and steamship construction; on modern materials such as ferroconcrete, sheet glass, and synthetics; and on contemporary needs such as town planning and housing projects.

• The International style of low-lying, unadorned buildings that depend for aesthetic effect on simplicity of forms and relation to function.

• What architecture should be!

How is Theory related to research Methodology?

Theory describes, explains, and predicts.

Research methodologies are: 1. Prescribed ways to test and prove or disprove those descriptions, explanations, and predications.

2. Provide a means by which theoretical claims to applicability beyond the particular case can be affirmed, modified, or rejected.

Theories are more general, but research methodologies are more specific.

Good Fit • There are usually “good fits” between Theory and Method (strategy).

4.2. The Framework of Theory in General Six components of a theory (Moore) 1. Propositions/observations about some aspect of the universe (something visible and knowable) 2. Logical connections between the propositions (abstract factors) 3. A set of conclusions drawn from #1 and #2 that the logical connections can be used to predict the propositions or observations

4.2. The Framework of Theory in General Six components of a theory (Moore) 4. Linkages to empirical reality; i.e. assumption that the factors in #2 can be used to accurately represent empirical reality. (Empirical is: Relying on or

derived from observation or experiment: empirical results that supported the hypothesis. Verifiable or provable by means of observation or experiment: empirical laws.

Guided by practical experience and not theory, especially in medicine.)

5. A set of assumptions or presuppositions underlying the theory.

6. Testability of the theory: related both to its internal logical coherence (understandable by others) and its applicability to other cases.

4.2. The Framework of Theory in General 2 added components of a theory (Moore) 1. Disciplinary domain 2. Philosophical axioms

Example of an Architectural Theory • David Canter  Theory of Place • Physical environments take on significance as a result of the Physical interaction of three domains: Physical locale, Activity performed in that locale and the meanings assigned to that Activities Meanings union of place with activity.

• “Constituents of Places”

4.3. Different Ways to Conceptually Divide Theory in General 4.3.1. Positive vs. Normative Theory • Positive theory: Descriptive and explanatory – Identify causal links - Predicts future behaviors of objects based on identified causal links. (definite, scientific, logical rigor) • Normative theory: Describe, explain and predicts future behaviors based on long-term usage or accepted, but not proven “truths”.

– These do not have the same rigor of proof (testing) as positive theory and can have a variety of results. (Design or architectural theory)

John Lang “Creating Architectural Theory” • Architectural theory: Behavioral concerns related to the process of designing environments.

4.3. Different Ways to Conceptually Divide Theory in General 4.3.2. Big, Medium and Small Theories • Big theories are large in scope — link several phenomena into one explanatory framework that is transferable to other disciplines • Small theories are limited in scope — localized explanations of things, not necessarily transferable to other situations • Medium theories have a little of both and are useful within a certain discipline, but will not have wide applicability across disciplines

4.3. Different Ways to Conceptually Divide Theory in General 4.3.3. Polemical Theories of Design • Polemic: A controversial argument, especially one refuting or attacking a specific opinion or doctrine. A person engaged in or inclined to controversy, argument, or refutation.

• In this case, different “theories” of architectural design that take opposite or varying stances on a certain concept.

Example of Polemically Theories Related to Design Activities • Set of visual attributes  Pugin “pointed gothic architecture” • How cultural time should be expressed in architectural form  Ginzburg, Venturi “Complexity and Contradiction in Architecture” • How natural processes ought to be expressed in material form  Sullivan “Form ever follows function”

Scientific Theories vs.

Theories of Design • Designers tend to discuss ‘theories’ of what should be done” • Scientists refer to ‘theories’ of “what might be the case”

4.3. Different Ways to Conceptually Divide Theory in General 4.3.4. Prediction vs. Persuasion • Positive Theory identifies “causal” links that lead to “predictions” of future behavior.

• Design “theories” tend to have less predictability (no causal links, testing), and are based rather on rhetoric and persuasion (generalizability depends on how subjectively universal it claims to be or how much it is understood by a large group of people; i.e. cultural).

• Positive and polemical design theories emerge out of a cultural context.

Example of Polemical Architectural Design Theories • Mies  “Less is More” – Machine aesthetic – Human identity

Example of Polemical Architectural Design Theories • Sullivan  “Form Ever Follows Function” It is the pervading law of all things organic and inorganic, Of all things physical and metaphysical, Of all things human and all things superhuman, Of all true manifestations of the head, Of the heart, of the soul, That the life is recognizable in its expression, That form ever follows function.

This is the law.
