The Critical Search for Knowledge
A Beginners Guide
|
Ancient Claims to Knowledge Mankind's
earliest source of reliable knowledge was verbal testimony, regardless
of whether the words derived from mortal or immortal sources, or were
the metaphors of some private experience. An uncritical acceptance of
that which was heard, and later of that which was read. Alas
this is still a factor in Knowledge claims today, particularly within
Institutions and Academia. |

SCEPTICISM Late Scepticism - Critical of the paralysis of some Pyrrhonist Sceptics rival schools variously adopted social convention, observant experience or probability as guides for belief dependent action. Creating what might be called Conservative Scepticism, Scientific Scepticism and Radical Scepticism. The Roman Sceptic Sextus Empiricus outlined five tenets or 'modes' of radical scepticism: Dissent
- All convention is uncertain.
Scientific Solution - It can be further argued that scientific experimentation bypasses appearance and deals directly with reality, and so is the only way to knowledge. Though this is only true for the data collected, the conclusions still rely on human opinion. So rival theories require a criterion of selection. Moreover even the data is often collected by instruments whose design depends on scientific theory. Thus many scientists admit they deal with useful hypotheses rather than truth. Hegel's Solution - A criterion for hypothesis selection can be chosen at random, the chosen hypothesis may prove useful or fail. A failed hypothesis points the way to an alternative and the adoption of a new criterion, and so on. The simplest scheme being a comparison between evolving opposite opinions, from which emerges the Dialectical Method. Modern Science arguably adopts a similar but more haphazard approach, with no overall system or methodology. Compromise?
- Radical Sceptics who base their judgment on probability can adopt any
mode of cognition that produces results for them or others, but usually
accept the likelihood that science is the |

Scientific
Methodology Experimental
Method - General Induction is not enough for Science which seeks
to answer specific questions or solve particular problems. Knowing
a stone falls when dropped is not as useful as knowing all the conditions
for and factors in the descent and how they effect it, nor does it
help us build predictive theories about the nature of falling objects
or the causal mechanisms involved. For this reason a more controlled
form of Induction is required which controls all the conditions of
observation, screens out any influencing factors not being studied,
modifies variables and isolates the phenomenon under study. The extent
to which this is possible depends on experimental design, the nature
of the phenomena and the preconceptions of the experiments designer.
Limits
of Experimentalism - The methodology is of course an idealization
which may not be followed or followable, even on a collective basis.
Anyone performing college based experiments in class will know only
a few will achieve the 'expected result' and the rest will copy the
results. The situation is not that different in professional science.
Optimal conditions are harder to achieve than many believe and most
scientists are not above tweaking the results. In extreme cases a
scientist with a career or theory to promote or defend will understandably
falsify results. The Problem of Observation and Visualization - A deeper problem is one of human perception. If our sensory experience is as mediated and as shaped by representative categories as it appears to be, how can we ever observe the real world? Instrumental measurement of unsensed physical data is one way round this, but this still requires interpretation, usually 'visually', using concepts shaped by our perceptions. Quantum Physics seems to show that our representive categories, such as position, motion and even space and time, are entirely artificial and conveniently mediate a simplified picture of a much stranger reality. Not surprisingly some scientists have given up on interpretation and deal solely with formuli.
Scientific
Theoritization - The aforementioned limits have
been the limits of experimentalism and data gathering, but this alone
even when successful only gives us a set of results which then have
to be interpreted. This on the face of it is simple pattern recognition,
whether we generalize a rule or law from the data or devise a whole
theorem based on it. The hypothesis that 'bests fits the evidence'
is chosen. This is the reliable way we arrive at all our views of
the world, but what does 'best fit' mean, and what if there seems
to be several 'good fits'? This returns us to the problem of the criterion.
All criterion of this kind have their strengths and weaknesses and
so many scientists simply rely on intuition or guess work and then
use secondary criteria to test their theory. A variant form of Falsificationism is Disconfirmation were predicted results do not manifest or where the results that do emerge can be 'better' accounted for by an alternative theory. The latter begs the question of the criteria for theory selection however, while the former is no grounds for completely discarding a theory, as the name implies, but simply requires theoretical or experimental modification as with Falsification.
Scientism
vs Pragmatism - Despite these clear limits some scientific sceptics
have insisted contemporary science is the only route to reliable knowledge,
with its 'securer' theories being the nearest thing we have to truth,
and all else being false, or at best untested, opinion. Though they
sometimes use selective 'truths' to support their own opinions. Those
that extend this theory of knowledge to a theory of meaning also claim
'positivistic' scientific statements are the only meaningful ones
(despite the fact that others have no problem finding meaning in non-scientific
statements). This move to scientific conviction is in many ways a
form of religion, aptly term Scientism. To deny this would either
be an over-evaluation of science or an under-evaluation of the strengths
of existential religion. Either way it is far removed from true scepticism. |

Logic A
more contemporary view of Logic is to see it as reflecting the ideal
structure of human reason. Either what it is or more likely what it
approximates. The religious view thus being an anthropomorphic projection. There are now many different forms of Logic, based on different theories of how the world, or our mind, is structured. But Classical Logic, with its binary notions of true or false, remains the common sense view. Of course we not reject it or this very web site and its arguments would not be possible, but it remains an open mystery. Certainly logic is a human construction dependent on our specific language and neurology, but it also attempts to capture the 'rational' aspects of reality. But where one ends and the other begins remains uncertain. One
thing that has been proved logically is that a formal description
can never be a complete one. Certainly in particular kinds of description,
and it would seem so in all. We can't attempt to describe everything
in total without leaving something out. This is typified by the paradox

The Psychology of Knowledge The
psychological function of knowledge is simply to reduce anxiety. Knowledge
may have the selected significance of instrumental utility but it does
so by creating stress in its absence, this is the true motivator for
knowledge, as with any power drive, powerlessness creates anxiety and
depression, as those who have experienced it well know. Given the anxiety base of the search for knowledge, those already under stress, whether from external or internal instability tend to be the most dogmatic of knowledge claimants and the most rigid or formal in their logical structuring of it. But this doesn't mean that all logicians are crazy or paranoid! It does mean that those under less stress will adopt theories as they should be adopted as pure hypotheses. Similarly authoritarian social orders depend on tightly controlled belief systems and so also rely on the creation of insecurity and fear, whether the source is 'hellfire' and 'demons' or 'social chaos' and 'terrorism'. It
is not only complete world views or ideologies that have this psychological
effect of course items of belief such as Cause and Effect are also rooted
in this security assurance. This
does not mean the views we obtain are false of course, some may be true
by virtue of the A related milder form of this human syndrome is the tendency to desire conceptual unity, a theory of everything, or overall body of coherent and consistent knowledge. This is related to the anxiety syndrome but is more deeply rooted. It relates more closely to the structure of the human mind and language that is biased towards 'coherent systems'. This creates a tunnel vision in science in particular, where all new data is assessed and filtered through a broader established belief system, or holistic 'web of belief', comprising the total body of conventional wisdom and accepted belief. Simplistically put, all new knowledge has to fit into what we 'already know', even if what we 'already know' is false or misleadingly only 'half true'. Thus original and innovative perspectives can be suppressed in the face of older biases. Another example of psychological cognitive filtering is the selection of theoretical models isomorphic to one's own culture. Thus the metaphysics of particles, seperation and exchange became dominant with the emergence of a Capitalist system, while a metaphysics of holism and connectivity becomes dominant under more Communal socio-economic systems. This does not mean the theories are necessarily wrong, it just explains their dominance in any arbitrary selection system. A
more positive application of Psychology would be the demonstration of
Intuition in cognitive processes. However despite its familiarity Intuition
is an extremely vague phenomena. There are actually three different
uses of the term. What we might call surface intuition is the idea of
pattern recognition. This is very closely related to Inductive reasoning,
but is instantaneous rather than linear in its connection of facts.
Likewise it is prone to illusion and psychological bias, as anyone who
has looked at inkblots will realize. Despite this it is extremely useful
and probably the first stage of all scientific thought. It does not
give certain knowledge however. |

The Epistemic Reaction The perceived danger to human progress allegedly inherent in total scepticism, as well as the anxiety it produced for some, led to a form of anti-scepticism known in philosophy as epistemology (literally the study of knowledge claims, ultimately from the same root word as epistle). The agenda of epistemology is to counter the claims of the sceptics and develop positive arguments for rational and scientific methodology. A traditional way to go about this was set down, during the emergence of Science and religious contention and decline in the 17th century, by the philosopher Descartes, who took the role of absolute sceptic to its limit, and then attempted to extricate himself. Descartes took up many classical sceptical arguments and invented new ones of his own. His ultimate argument was that we have no way of knowing we are not constantly dreaming and so can doubt everything (this was modernized in the 20th century as the Brain-in-a-Vat argument, which partly inspired the film the Matrix). Descartes then extracted himself by claiming the only thing he couldn't doubt was that he was doubting (as doubting this would only affirm it). From this he argued that he himself as a doubter must therefore exist (modern arguments that doubting could take place without a doubter seemed as absurd to him as it does to most modern readers). As doubt was just a mode of thought, he produced his truism, 'I think therefore I am'. From this he argued on the basis of the consistency of his experience, and its lucidity and difference to dreams, that there was an external reality and other people. Later epistemic arguments added the existence of coherent language (arguably a social product rather than a private one), including its possibility for error, proved the existence of others in some shared reality. Descartes then made a leap of faith and assumed that the regularity and consistency of the world must have a source, which he identified as God. From which he derived more of a theological than philosophical argument that God must be perfect, and therefore benign, and a benign God would ensure our senses were reliable and human reason mirrored the order of the world making it knowable. This then was a short step to the acceptance of Science as the road to truth. In the process of all this he created a schizoid world view in which God and Nature, spirit and matter and psyche and body all had an equal but disconnected reality. All subsequent epistemology and European philosophy in general can be seen as a reaction for or against Descartes view or various modifications of it. Descartes
position was what today would be called a form of Foundationalism, one
of the main schools of Epistemic faith. It takes many forms but all
believe that there exist facts that are either self evident or undeniable
and from these bare foundational facts logical certainties can be deduced.
The problem with it is all the foundations proposed are in fact doubtable
and the few which might achieve a consensus, such as self existence
or the inertia of reality, don't really take as very far, particularly
if we also question logic. Hense post-modernists can argue for the bare
existence of language and (maybe)
language users. Other
positions are basically those described early under the Scientific Method.
With the exception that it is either expanded to produce a universal
account of everything knowable In
practise most modern analytical philosophy attempts to resolve the various
problems described above and posits epistemologies that are often hybrids
of the standard positions we have explored. Though it is not at all
clear that combining three bad ideas makes a good idea.
Skepticism
- One of the strangest combined responces to both Radical Scepticism
and naive True Belief has been that form of 'critical thought' popularly
known as 'Skepticism'. My which I mean the belief system behind such
publications as the Skeptical Enquirer. American English spells 'sceptic'
as 'skeptic' so this distinction is harder to see, but in conventional
English the 'skeptic' spelling has been adopted to denote a different
meaning. This type of thinking evolves out of the earlier Scientific
Scepticism outlined above, but is far more naive in its uncritical acceptance
of established scientific knowledge and methodology. Most of its proponents
far from being true sceptics are instead 'true believers' with a strong
faith in Scientism, which becomes their yardstick against which all
other claims are assessed. A similar ungrounded faith in Logic is also
often present, which often embraces dubious logical concepts like the
'burden of proof' (the notion of 'innocent till proven guilty' found
in some legal systems misplaced as a logical principle only 'proven
claims' are true or legitimate). Unfortunately such Skepticism is is
often badly motivated, not just by faith in Scientism, but by more negative
beliefs such as Atheism (which is as biased an ideology as Theism and
Deism , with the true Sceptic always taking an Agnostic position). There
is also a variety of biased political positions involved, mostly involving
idealistic, authoritarian notions of the control of nature, society
and the individual through Science, a dystopia shared by many Capitalists,
Humanists and Communists alike. The financial framework created by governments
and ruling elites which hold these political agendas also distorts the
academic and intellectual environment. Some sociologists even regard
Skepticism as a pathological form of the psychological conditions mentioned
above. For these reasons I would discount this position as part of a
genuine Radical Scepticism aimed at liberating people. |

The Continental Approach So
called Continental Philosophy, or that part of it excluding the Anglophile
school, has evolved in opposition to the kind of analytical position
outlined above. Its proponents regarding it as a revolutionary alternative
perspective, its detractors see it as symptomatic of muddled thinking
if not insanity.Unfortunately the divide was often political in context. German Idealism - A school accepting Descartes view, but denying the reality of his material phenomena, as merely perceptual images created in mind, or within a broader God, just as the Anglo school denied the reality of Descartes mental phenomena, as merely the products of material brains and Nature. Thus knowledge of the world was directly contactable. But the resistance of the apparently concrete world to any mind, collective human aspiration or moral development, unexpected and even irrational discoveries in it, and the successes of material technology have tended to marginalise this position, if not refute it completely. Epistemically the failure to gain any consensus via intuition is also damning for this perspective. Kantianism
- Kant's notion that the world we experience is a mental construction,
based on manmade concepts, that filter a more mysterious and alien externality
to us, is now almost universally accepted. His broader philosophy that
the real world is entirely rational, not directly experienced, and knowable
through rational analysis alone is far more contentious, and now, partly
due to the critiques of Nietzsche - and the Existentialists and Phenomenologists
who followed in his wake - is almost universally rejected as a rationalist
fantasy. For these critics reality is something more vague and mysterious,
and all that really matters is the world of experience, which was accessible
to us directly, but whose relation to any deeper reality is unknowable. Structuralism and Post Structuralism - The disillusionment with Idealism, amongst the Anti-Materialists, and/or Anti-Realists, as well as the vagueries of free floating Existentialism, led to the embrace of language as the structuring frame of experience. This trend took the form of a kind of loose Coherentism based on syntax and semantics rather than strict logic, but retained many of the problems of this view. The reaction in opposition to this as well as the attempt to resusitate elements of it gave birth to a variety of post structuralist theories. Many of these strenghtened scepticism rather than weakened it however. Post
Modernism - Could be seen as the ultimate Sceptical position against
any ideological or fixed viewpoint, as well as the hegemony of Reason
and a notion of any Objective Reality, arising from a Post Structuralist
framework. It is however a deeply paradoxical position in that it remains
wed to certain theories of language as well as what is essentially a
materialistic paradigm. Its more naive proponents claim this paradox
is part of its rejection of logic, however its own assumptions are grounded
in an unexamined pre-logical Rationalism that it cannot itself support. |

Preliminary Conclusions The only conclusion the Radical Sceptic can really derive from these considerations is that certainty of knowledge is impossible, outside a few basic considerations (such as self existence and anti-solipsism) and some pragmatic scientific theories, and the 'natural laws' they reveal, with a limited and probabilistic applicability (outside of the near certainties of Quantum Mechanics, which seem to be beyond human reason anyway). Scientific Scepticism as an alternative fails on this limited scope of Science (without degenerating into an oppressive Scientism), and in practice its reformed mode becomes little different to Radical Scepticism. The danger in this for those who seek a liberation through Scepticism is a decline either into Nihilism, where nothing is believed, or a negative Liberalism, where everything is potentially believable. Both of which have obvious conservative consequences as they make decisive, pre-emptive or even positive counter action impossible. However
there is nothing within Scepticism that precludes personal, pragmatic
belief, or holding those beliefs with as much force as is desired
(regardless of whether they are theoretical approximations or useful
myths). This allows a far wider range of potential beliefs than most
other positions allow, particularly when the pragmatism is based as
much on personal experience as on collective experience. The only
practical criteria would be a means of avoiding the imposition of
one belief system on another - declarations that 'might is right',
or that the 'majority is right', or even 'seduction (i.e. soft imposition)
is right', are of course just other ideologies subject to scepticism,
and so can't be used as a meta-level framework if universal liberty
is our aim. Given the inescapability of personal bias, a form of disciplined,
individualism seems called for, to balence the drive for social change.
As well as perhaps a radical form of enlightened self interest that
survives all sceptical rigour.
