 is a rational argument in this sense). The other part associates rationality with explanation, understanding or justification, particularly if it provides a ground or a motive. 'Irrational', therefore, is defined as that which is not endowed with reason or understanding.

 arguments are logically unsound, but in many cases they may be rational. A simple philosophical definition of rationality refers to one's use of a "practical syllogism". For example,

I am cold
I don't want to be cold
If I close the window I will not be cold...
Therefore, I will close the window

All that is required for an action to be rational is that if one believes action X (which can be done) implies Y, and that Y is desirable, he or she does X. The action would likewise be avoided were Y undesirable. Such arguments are logically valid

s are often called rational if they tend to act somehow optimally in pursuit of their goals. Thus one speaks, for example, of a rational allocation of resources, or of a rational corporate strategy. In this concept of "rationality", the individual's goals or motives are taken for granted and not made subject to criticism, ethical or otherwise. Thus rationality simply refers to the success of goal attainment, whatever those goals may be. Sometimes, in this context, rationality is equated with behavior that is self-interested to the point of being selfish. Sometimes rationality implies having complete knowledge about all the details of a given situation.

Debates arise in these three fields about whether or not people or organizations are "really" rational, as well as whether it make sense to model them as such in formal models. Some have argued that a kind of bounded rationality

Quality of Rationality


It is believed by most philosophers (A.C Grayling) and experts, that a good rationale must be independent of emotions, personal feelings or any kind of instincts. Any process of evaluation or analysis, that may be called rational, is expected to be highly objective, logical and "mechanical". If these minimum requirements are not satisfied i.e. if a person has been, even slightly, influenced by personal emotions, feelings, instincts or culturally specific, moral codes and norms, then the analysis may be termed irrational, due to the injection of subjective bias.

However, it is difficult for most common people to satisfy these requirements, as it requires a great degree of intrapersonal intelligence to maintain high standards of immunity from emotions and a detailed understanding of procedure of reasoning. Moreover, a number of issues may be analysed by people who have a very culturally specific understanding of ethics, which may further make it likely for their opinions to be irrational.

Theories of rationality


The German sociologist Max Weber
Max Weber

Maximilian Carl Emil Weber was one of the most profoundly influential thinkers of the twentieth century. Born in Germany, Weber became a lawyer, politician, scholar, political economy, and sociology....
 proposed an interpretation of social action that distinguished between four different types of rationality. The first, which he called Zweckrational or purposive/instrumental rationality, is related to the expectations about the behavior of other human beings or objects in the environment. These expectations serve as means for a particular actor to attain ends, ends which Weber noted were "rationally pursued and calculated." The second type, Weber called Wertrational or value/belief-oriented. Here the action is undertaken for what one might call reasons intrinsic to the actor: some ethical, aesthetic, religious or other motive, independent of whether it will lead to success. The third type was affectual, determined by an actor's specific affect, feeling, or emotion - to which Weber himself said that this was a kind of rationality that was on the borderline of what he considered "meaningfully oriented." The fourth was traditional, determined by ingrained habituation. Weber emphasized that it was very unusual to find only one of these orientations: combinations were the norm. His usage also makes clear that he considered the first two as more significant than the others, and it is arguable that the third and fourth are subtypes of the first two. These kinds of rationality were ideal types.

The advantage in this interpretation is that it avoids a value-laden assessment, say, that certain kinds of beliefs are irrational. Instead, Weber suggests that a ground or motive can be given – for religious or affect reasons, for example — that may meet the criterion of explanation or justification even if it is not an explanation that fits the Zweckrational orientation of means and ends. The opposite is therefore also true: some means-ends explanations will not satisfy those whose grounds for action are 'Wertrational'.

Weber's constructions of rationality have been critiqued both from a Habermasian (1984) perspective (as devoid of social context and under-theorised in terms of social power) and also from a feminist perspective (Eagleton, 2003) whereby Weber's rationality constructs are viewed as imbued with masculine values and oriented toward the maintenance of male power. The first stirrings of an alternative position on rationality (which includes both bounded rationality (Simons and Hawkins, 1949), as well as the affective and value-based arguments of Weber) can be found in the critique of Etzioni (1988), who reframes thought on decision-making to argue for a reversal of the position put forward by Weber. Etzioni illustrates how purposive/instrumental reasoning is subordinated by normative considerations (ideas on how people 'ought' to behave) and affective considerations (as a support system for the development of human relationships).

Use of the term rational


In a number of kinds of speech, "rational" may also denote a hodge-podge of generally positive attributes, including:

  • reasonable: "having sound judgment and practical implementation" (Webster's)
  • reasonable: "not extreme or excessive" (Webster's)
  • justifiable on the basis of reason

 is used in a slightly different way than in general. Here rationality is defined contextually as the constructive tendency and leaning that humans have to acts, emote and think in ways that are alternative-seeking, realistic, flexible and most importantly self- and social-helping and functional in helping humans in achieving their personal and social goals and desires.
