Session Ident: #philosophy
[19:57] *** Now talking in #philosophy
[19:57] <larchie> The Philosophy Chat is now
open
[19:57] <larchie> for discussion of Test I:
The Structure of Arguments
[19:57] <larchie> ...
[20:01] <larchie> Hi Kyle
[20:01] <larchie> ...
[20:01] <guest> hey larchie
[20:01] <guest> haha lots of people here
[20:01] <larchie> Just you so far.
[20:01] <guest> yea I was joking
[20:02] <larchie> Last night no one showed up
after 20 min...
[20:02] <guest> What is a the difference
between a argument and explanation?
[20:02] <larchie> Several things-- first the
intent
[20:02] <larchie> the argument seeks a proof
whereas a
[20:03] <larchie> an explanation answers
"why"
[20:03] <larchie> but the main difference is
that an
[20:04] <larchie> explanation goes from less
well known information to better known information
[20:04] <larchie> There a table here which
points out more
[20:04] <larchie> differences
[20:04] <larchie>

[20:04] <guest> alright, what about truth
validity and soundness. keep it simple. I understand them...i think
[20:05] <larchie> what do you want to know
about truth and validity?
[20:05] <larchie> The notes in the syllabus
are pretty thorough
[20:06] <larchie> can you be more specific
[20:06] <guest> just the part were it says to
be able to list differences
[20:06] <larchie> Truth is a property of
statements
[20:06] <larchie> Validity is a property of
arguments
[20:06] <larchie> Soundness is a property of
both statements and arguments
[20:07] <guest> alright thanks!
[20:08] <larchie> More detail on these
specific differences are given here
[20:08] <larchie>

[20:08] <guest> my employer Chuck Watson said
he had you for a teacher....20 sum years ago.
[20:08] <larchie> I remember Chuck well--I am
surprised it's been that long
[20:08] <guest> haha
[20:09] <larchie> What's he up to now?
[20:09] <guest> Just still in to law.
[20:09] <guest> Nice guy!
[20:10] <guest> he told me that you would say
he got a B in your class but he he got an A
[20:10] <larchie> I'm not surprised
[20:11] <guest> he jokes alot
[20:11] <larchie> As in class lo those many
years ago
[20:12] <guest> well thanks for the help
[20:12] <larchie> sure, anything else?
[20:12] <larchie> Be sure to come to class
with examples in mind of
[20:12] <larchie> a statement and a sentence
which is not a statement
[20:13] <larchie> and an argument and an
explanation
[20:13] <larchie> and a deductive and
inductive argument
[20:13] <larchie> Or you can pull examples
from the
[20:13] <larchie> test itself.
[20:13] <larchie> The most missed indicators
will be
[20:13] <larchie> "because" and
"accordingly"
[20:14] <larchie> other than that the test is
very close to
[20:14] <larchie> the online example test.
[20:14] *** tink85 has joined #philosophy
[20:14] <guest> ok, thank!
[20:14] <larchie> you're welcome
[20:15] <larchie> Hi Tamara
[20:15] <larchie> Just Kyle and I are in the
Chat with you.
[20:18] <larchie> Tamara are you in the
philosophy channel?
[20:18] *** tink85 has quit IRC (Quit: Leaving)
[20:19] <larchie> Tamara logged into a
different channel apparently.
[20:21] <larchie> ...
[20:23] *** guest has quit IRC (Quit: Leaving)
[20:23] *** guest has joined #philosophy
[20:26] <guest> Hi is this logic?
[20:26] <larchie> Yes, any questions
[20:26] *** guest has quit IRC (Quit: Leaving)
[20:27] *** tink85 has joined #philosophy
[20:28] <larchie> Hi Tamara--I missed your
message earlier
[20:28] <tink85> I was doing the problems
from Problem Set3: Diagramming Arguments and had should with question number 3
& 5
[20:28] <larchie> somehow you logged on to a
different channel
[20:29] <larchie> o.k. let me take a quick
look
[20:29] <tink85> I know have to get use to
using the computer besides just checking my e-mail and writing papers sorry!!
[20:29] <larchie> no problem
[20:30] <larchie> on #3 the premisses are 1
and 3 which lead to 2
[20:30] <larchie> and the argument is
inductive..
[20:31] <larchie> on #5
[20:31] <tink85> Is it okay to type out the
problem to make sure we are talking about the same one?
[20:31] <larchie> 1 is the conclusion and all
the rest are premisses
[20:31] <larchie> hold on I cut and paste
[20:31] <larchie> 3--1) Students who napped
for an hour improved in their ability to detect subtle changes in an image. (2)
Hence, daytime dozing may enhance a person's capacity to learn certain tasks
(3) since students who didn't nap declined in their ability to identify the
changes.
[20:32] <larchie> #5--(1) By age 3, children
diagnosed with autism have already begun a retreat into social isolation. The
evidence is as follows: (2) Three groups of children were studied: those with autism,
those with a developmental disorder, and those with no developmental disorder.
(3) Each child wore a cap that recorded brain-wave responses as experimenters
presented images of his or her mother's face, an unfamiliar woman's face, a
favorite toy from home, and an unfamiliar toy. (4) Spikes in the brain's
electrical activity signaled recognition of the mother's face and the favorite
toy in both healthy chil
[20:32] <larchie> right??
[20:32] <tink85> yes sir that is the correct
one
[20:33] <larchie> also 5 is inductive
[20:33] <larchie> did you get the structure
above for #5?
[20:33] <tink85> No sir
[20:33] <larchie> The conclusion is stated
first followed by the
[20:33] <larchie> evidence (which are all
premisses).
[20:34] <larchie> Hence (1) is the conclusion
and ...
[20:34] <larchie> (2)-(5) are premisses for
(1)
[20:35] <tink85> will we have a question like
this on the test?
[20:35] <larchie> Quite a few--
[20:36] <larchie> BTW if you get a chance be
sure to
[20:36] <larchie> check the Chat log for some
good
[20:36] <larchie> information earlier about
what's most
[20:36] <larchie> missed in the past on this
test.
[20:37] <tink85> okay thank you
[20:38] <tink85> With writing the definition
if we are able to give an example of the question do we have to write out the
wording
[20:38] <larchie> Yes, at least a
characterization or description that is accurate
[20:39] <tink85> okay thank you I believe
that was all of my questions
[20:40] <larchie> o.k. you're welcome
[20:40] <tink85> I was wrong were are the
other questions posted at?
[20:41] <larchie> which questions?
[20:41] <tink85> From the last chat
[20:41] <larchie> No one showed up--but click
on Chat Logs
[20:41] <larchie> on the homepage for Logic
and the
[20:42] <larchie> link to the chat is at the
bottom of the page
[20:42] <larchie> You'll see just me in the
Chat announcing
[20:42] <larchie> that it's open etc.
[20:42] <larchie> Go to
http://philosophy.lander.edu/logic/
[20:43] <larchie> then click on "Chat Logs"
link at the top left hand part of the page
[20:43] <larchie> Scroll down to
"Spring, 2007"
[20:44] <larchie> Tonight's questions won't
be posted until after this chat is over
[20:45] <tink85> Okay I will see you tomorrow
