Determine if there is a history of cardiac disease, malignancy, sepsis, or intercurrent illness. Determine if patient has been exposed to potentially nephrotoxic drugs antibiotics, NSAIDs, contrast agents, solvents. Conduct an ongoing physical examination for tissue turgor, pallor, alteration in mucous membranes, blood pressure, heart rate changes, pulmonary edema, and peripheral edema.
Thus claims to knowledge may be contrastingly and normatively evaluated. They are either falsifiable and thus empirical in a very broad senseor not falsifiable and thus non-empirical. Those claims to knowledge that are potentially falsifiable can then be admitted to the body of empirical science, and then further differentiated according to whether they are retained or are later actually falsified.
If retained, further differentiation may be made on the basis of how much subjection to criticism they have received, how severe such criticism has been, and how probable the theory is, with the least  probable theory that still withstands attempts to falsify it being the one to be preferred.
That it is the least  probable theory that is to be preferred is one of the contrasting differences between critical rationalism and classical views on science, such as positivism, who hold that one should instead accept the most probable theory.
The least probable theory is the one with the highest information content and most open to future falsification. Critical Rationalism as a discourse positioned itself against what its proponents took to be epistemologically relativist philosophies, particularly post-modernist or sociological approaches to knowledge.
Critical rationalism has it that knowledge is objective in the sense of Rationalism of failure embodied in various substrates and in the sense of not being reducible to what Rationalism of failure individually "know"and also that truth is objective exists independently of social mediation or individual perception, but is "really real".
However, this contrastive, critical approach to objective knowledge is quite different from more traditional views that also hold knowledge to be objective.
These include the classical rationalism of the Enlightenmentthe verificationism of the logical positivistsor approaches to science based on inductiona supposed form of logical inference which critical rationalists reject, in line with David Hume.
For criticism is all that can be done when attempting to differentiate claims to knowledge, according to the critical rationalist. Reason is the organon of criticism, not of support; of tentative refutation, not of proof. Supposed positive evidence such as the provision of "good reasons" for a claim, or its having been "corroborated" by making successful predictions actually does nothing to bolster, support, or prove a claim, belief, or theory.
In this sense, critical rationalism turns the normal understanding of a traditional rationalist, and a realist, on its head.
Especially the view that a theory is better if it is less likely to be true is in direct opposition to the traditional positivistic view, which holds that one should seek for theories that have a high probability.
Even a highly unlikely theory that conflicts current observation and is thus false, like "all swans are white" must be considered to be better than one which fits observations perfectly, but is highly probable like "all swans have a color".
This insight is the crucial difference between naive falsificationism and critical rationalism. The lower probability theory is favoured by critical rationalism because the higher the informative content of a theory the lower will be its probability, for the more information a statement contains, the greater will be the number of ways in which it may turn out to be false.
The rationale behind this is simply to make it as easy as possible to find out whether the theory is false so that it can be replaced by one that is closer to the truth. It is not meant as a concession to justificatory epistemology, like assuming a theory to be "justifiable" by asserting that it is highly unlikely and yet fits observation.
Critical rationalism rejects the classical position that knowledge is justified true belief ; it instead holds the exact opposite: That, in general, knowledge is unjustified untrue unbelief. It is unjustified because of the non-existence of good reasons.
It is untrue, because it usually contains errors that sometimes remain unnoticed for hundreds of years. It is only available as the content of books. Most justificationists do not know that they are justificationists.
Justificationism is what Popper called a "subjectivist" view of truth, in which the question of whether some statement is true, is confused with the question of whether it can be justified established, proven, verified, warranted, made well-founded, made reliable, grounded, supported, legitimated, based on evidence in some way.
According to Bartley, some justificationists are positive about this mistake. Other justificationists are negative about these mistakes. They are epistemological relativists, and think rightly, according to the critical rationalist that you cannot find knowledge, that there is no source of epistemological absolutism.
But they conclude wrongly, according to the critical rationalist that there is therefore no rationality, and no objective distinction to be made between the true and the false. By dissolving justificationism itself, the critical rationalist a proponent of non-justificationism  regards knowledge and rationality, reason and science, as neither foundational nor infallible, but nevertheless does not think we must therefore all be relativists.
Knowledge and truth still exist, just not in the way we thought. The pitfalls of justificationism and positivism[ edit ] Are all swans white? This seems hardly possible, since it would require us to infer a general rule from a number of individual cases, which is logically inadmissible. However, if we find one single black swan, logic allows us to conclude that the statement that all swans are white is false.
Falsificationism thus strives for questioning, for falsification, of hypotheses instead of proving them. The rejection of "positivist" approaches to knowledge occurs due to various pitfalls that positivism falls into. A thousand observations of some event A coinciding with some event B does not allow one to logically infer that all A events coincide with B events.
According to the critical rationalist, if there is a sense in which humans accrue knowledge positively by experience, it is only by pivoting observations off existing conjectural theories pertinent to the observations, or off underlying cognitive schemas which unconsciously handle perceptions and use them to generate new theories.
But these new theories advanced in response to perceived particulars are not logically "induced" from them.
|Thursday, December 9, 2010||No assessment of the Socratic project can avoid answering this question; it is difficult to view Socrates in a positive light unless we believe that his method is qualitatively different from the mere "sophistry" of a Protagoras or a Gorgias. Plato takes great pains to distinguish the two models of thought and education, and most subsequent analyses have tended to accept his sharp distinction and therefore to dismiss the Aristophanic portrayal as inaccurate and unfair.|

Rationalism Explanation According to the text, ”Rationalism is a doctrine which gives the discursive reason as the only possible source of all real knowledge. According to Louis-Marie Morfaux, rationalism takes in all doctrines that attribute to human reason the capacity to know and establish the truth.”.
Definition: Market failure, from yunusemremert.com: Market failure is the economic situation defined by an inefficient distribution of goods and services in the free market.
Furthermore, the individual incentives for rational behavior do not lead to rational outcomes for the group. Critical rationalism is an epistemological philosophy advanced by Karl Popper.
Popper wrote about critical rationalism in his works: The Logic of Scientific Discovery,  The Open Society and its Enemies,  Conjectures and Refutations,  The Myth of the Framework,  and Unended Quest.
