Chapter 3 Flashcards
Most cars have four wheels. The Empire State Building is over a thousand feet tall.
Each of these statements has a linguistic form as an English sentence. And each of the sentences has a meaning; it has a meaning. The meaning or thought is a ________
proposition
When we engage in reasoning, the units of thought are _____
Propositions
When we take a position on an issue, we are asserting that a certain _____ is true.
That a certain proposition is true
predicate
The predicate is the part of a sentence (or clause) that tells us what the subject does or is.
Propositions, and the sentences that express them, must have a _____ and a ______
subject and a predicate
In the following propositions (expressed through sentences that are comprised of subjects and predicates in order to be complete) which are the subjects and predicates?
For example:
Most cars have four wheels.
The Empire State Building is over a thousand feet tall.
Most cars = subject
Have four wheels = predicate
The Empire State Building = subject
Is over a thousand feet tall = predicate
Jack is a X. Jack is a Y. If x and y express the same concept then they assert the same proposition.
The following statements assert the same proposition, true or false? Jack is a lawyer (x). Jack is an attorney (y).
True. Lawyer and attorney are synonymous
Jack is a X. Jack is a Y. If x and y express the same concept then they assert the same proposition.
The following statements assert the same proposition, true or false?
Jack is a Baptist. Jack is a Christian.
False. Christian is a more abstract concept. Baptist would be a genus of Christian. So they do not assert or express the same proposition.
Sometimes when two words express the same concept they are usually considered synonyms, however we must also take into account the word’s ______?
For example:
Mary has form command of the subject matter
Mary has a thorough understanding of the subject matter.
Connotation
Top sentence expresses more power and the second is more generic and bland
Two words that express the same concept are usually considered to be synonyms: “couch” and “sofa,” “car” and “automobile,” “own” and “possess,” and so on. But sometimes words that express the same concept have different __________. They convey different images or feelings; they elicit different associations in our minds; they express different attitudes.
connotations
For each pair of sentences that follow, determine whether the sentence s express the same proposition:
- You have a lovely view from your window.

Same proposition
For each pair of sentences that follow, determine whether the sentence s express the same proposition:
- James is a journalist.
- James works for a newspaper.
Different proposition
For each pair of sentences that follow, determine whether the sentence s express the same proposition:
- The elderly person ahead of me was doing about 25 miles per hour.
- The geezer ahead of me was doing about 25 miles per hour.
Same proposition
For each pair of sentences that follow, determine whether the sentence s express the same proposition:

Strictly speaking, a _______ is a particular figure of speech in which one thing is equated to another in order to bring out some point of similarity, as in the example we discussed in the past chapter: “Life is a cabaret.”
Metaphor
Metaphors are distinguished from other figures of speech
such as _____: “Life is like a box of chocolates”
Similes
For example, when the poet Robert Burns said “My love is like a red , red rose,” he was making a comparison . He didn’t mean that he was dating a form of plant life. Presumably he meant his love was beautiful. Yet the two statements
- My love is like a red, red rose
- My love is beautiful
Determine whether the above sentences express the same proposition…
Do not express quite the same proposition.
Perhaps the Burns also means to say that his love is prickly and temperamental. You can see that it would be extremely hard to find a literal statement that asserts exactly the same proposition.
“Grasp” is a physical ______ for the mental act of understanding, but it has been used so often that understanding is now considered one of the literal meanings of the word. In such a case, there is no need for interpretation at all.
Metaphor
We often describe pains as “sharp,” people as “dense,” spicy food as “hot,” relationships as “stormy,” and so on. If you think about it, you can see that each of these terms is based on a ______ that is now incorporated into its literal meaning.
Metaphor
For the metaphorical statement, formulate a LITERAL equivalent:
The article “glossed over” the controversy.
The article over-simplified the information about the controversy
