Aristotelian logic dealt with inferences about concepts, and there were also proposition inferences [Weiner]
|
|
Full Idea:
Till the nineteenth century, it was a common view that Aristotelian logic could evaluate inferences whose validity was based on relations between concepts, while propositional logic could evaluate inferences based on relations between propositions.

A reaction:
Venn diagrams relate closely to Aristotelian syllogisms, as each concept is represented by a circle, and shows relations between sets. Arrows seem needed to represent how to go from one proposition to another. Is one static, the other dynamic?

It is nonsense that understanding does not involve knowledge; to understand, you must know [Dougherty/Rysiew]
|
|
Full Idea:
The proposition that understanding does not involve knowledge is widespread (for example, in discussions of what philosophy aims at), but hardly withstands scrutiny. If you do not know how a jet engine works, you do not understand how it works.

From:
Dougherty,T/Rysiew,P (Experience First (and reply) [2014], p.24)
|
|
A reaction:
This seems a bit disingenuous. As in 'Theaetetus', knowing the million parts of a jet engine is not to understand it. More strongly - how could knowledge of an infinity of separate propositional truths amount to understanding on their own?

Rather than knowledge, our epistemic aim may be mere true belief, or else understanding and wisdom [Dougherty/Rysiew]
|
|
Full Idea:
If we say our cognitive aim is to get knowledge, the opposing views are the naturalistic view that what matters is just true belief (or just 'getting by'), or that there are rival epistemic goods such as understanding and wisdom.

From:
Dougherty,T/Rysiew,P (Experience First (and reply) [2014], p.17)
|
|
A reaction:
[compressed summary] I'm a fan of understanding. The accumulation of propositional knowledge would relish knowing the mass of every grain of sand on a beach. If you say the propositions should be 'important', other values are invoked.

If knowledge is unanalysable, that makes justification more important [Dougherty/Rysiew]
|
|
Full Idea:
If knowledge is indeed unanalyzable, that could be seen as a liberation of justification to assume importance in its own right.
|
|
From:
Dougherty,T/Rysiew,P (What is Knowledge-First Epistemology? [2014], p.11)
|
|
A reaction:
[They cite Kvanvig 2003:192 and Greco 2010:9-] See Scruton's Idea 3897. I suspect that we should just give up discussing 'knowledge', which is a woolly and uninformative term, and focus on where the real epistemological action is.

Men are created equal, and with certain inalienable rights [Jefferson]
|
|
Full Idea:
We hold these Truths to be self-evident, that all Men are created equal, that they are endowed by their Creator with certain inalienable rights, that among these are Life, Liberty and the Pursuit of Happiness.
|
|
From:
Thomas Jefferson (U.S. Declaration of Independence [1775]), quoted by Johanna Oksala - Political Philosophy: all that matters Ch.4
|
|
A reaction:
In the context, saying equality and rights are 'natural' is just a way of saying we will fight to the death to defend them. The big modern problem for the U.S. is that nominal equality before the law doesn't ensure equality in society.
