Thought and Machine: Some Wittgenstein's
Comments
|
I
analyze Wittgenstein's criticism of several assumptions that are
crucial for a large part of cognitive science. These involve the
concepts of computational processes in the brain which cause mental
states and processes, the algorithmic processing of information in the
brain (neural system), the brain as a machine, psychophysical
parallelism, the thinking machine, as well as the confusion of rule
following with behaviour in accordance with the rule. In my opinion,
the theorists of cognitive science have not yet seriously considered
Wittgenstein's criticism so they, quite surprisingly, frequently
confuse the question "how does it work?" with "what does it do?" But
their most "deleterious" mistake is their confusion of the
internal computational (or parallel) processes taking place in the
brain (which possibly cause mental states) with socially-based,
everyday criteria of recognition and classification of, and knowledge
about, the content of mental states.

Mathematics: Application and Applicability
|
This paper attempts
a new classification of types of applications of mathematics by
dividing applications into: (a) canonical versus
noncanonical applications; (b) empirical versus nonempirical
applications. This generates four different kinds of
applications, each of which has its own interest. The canonical
applications of a mathematical concept or theory are those applications
the concept or theory was formulated to describe in the first place.
A good part of this paper is devoted to a new look at elementary
arithmetic, with an eye to discovering its canonical
applications. One of the surprises of this paper is the discovery
that some of the canonical applications of arithmetic are nonempirical,
a conclusion that has importance for the teaching of arithmetic.
Another discovery with pedagogic implications is that there is a
tendency to confuse arithmetic operations with their canonical
applications. If there is time, I will discuss noncanonical
applications, such as those ones treated in my recent book (Harvard,
1998).

Time and Tense
|
Temporal
features of events can be characterised in two different ways: first,
using the unchanging relations of Earlier than, Later than, or
Simultaneous with. If an event is ever earlier than another event, it
is always earlier. The second way to characterise temporal features is
to use the changing categories of Past, Present, and Future; an event
that was once future is now present, and soon will be past. Following
McTaggart, we call the series formed by the first type of relations the
B-series. and the series formed by the second categorization the
A-series.
Temporal features of events can be described in a
language by tensed and tenseless expressions. The truth-value of tensed
sentences depends on the time of their use, the truth-value of
tenseless sentences doesn't.
These features may suggest an immediate
affinity between tensed language and the A-series on the one hand, and
tenseless language and the B-series on the other. And indeed, many
philosophers argued that we can reach conclusions about the nature of
time on the basis of certain features of temporal language.
In this talk, I develop an outline of a theory
of temporal language, and see whether we can infer anything from this
about the nature of time.

Gyorsuló univerzum
(Accelerating
universe)

Napjaink
kozmológiája látványos és váratlan
eredményeket produkál: nagy
pontossággal megmérték a kozmikus háttérsugárzás
szögeloszlását, a galaxisok térbeli
eloszlásfüggvényét, közben kiderült,
hogy az univerzum gyorsulva tágul, és hogy az általunk
ismert anyag a teljes tömegnek mindössze 5 százalékát
alkotja. Lehet, hogy mégis van kozmológiai állandó, amely sötét
energia fedőnéven 75 százalékát adja a
teljes energiának. Az előadás
ezekről a kérdésekről és a ma rájuk
adott magyarázatokról kiván rövid áttekintést
adni. Felvetjük azt a kérdést, hogy az univerzum
jövőjére vonatkozóan mit mondhatunk az új
tények ismereteben. |
