There are several logics, none of which will ever derive falsehoods from truth [Lewis,CI]
|
|
Full Idea:
The fact is that there are several logics, markedly different, each self-consistent in its own terms and such that whoever, using it, avoids false premises, will never reach a false conclusion.
|
|
From:
C.I. Lewis (A Pragmatic Conception of the A Priori [1923], p.366)
|
|
A reaction:
As the man who invented modal logic in five different versions, he speaks with some authority. Logicians now debate which version is the best, so how could that be decided? You could avoid false conclusions by never reasoning at all.

Excluded middle is just our preference for a simplified dichotomy in experience [Lewis,CI]
|
|
Full Idea:
The law of excluded middle formulates our decision that whatever is not designated by a certain term shall be designated by its negative. It declares our purpose to make a complete dichotomy of experience, ..which is only our penchant for simplicity.
|
|
From:
C.I. Lewis (A Pragmatic Conception of the A Priori [1923], p.365)
|
|
A reaction:
I find this view quite appealing. 'Look, it's either F or it isn't!' is a dogmatic attitude which irritates a lot of people, and appears to be dispensible. Intuitionists in mathematics dispense with the principle, and vagueness threatens it.

We can maintain a priori principles come what may, but we can also change them [Lewis,CI]
|
|
Full Idea:
The a priori contains principles which can be maintained in the face of all experience, representing the initiative of the mind. But they are subject to alteration on pragmatic grounds, if expanding experience shows their intellectual infelicity.
|
|
From:
C.I. Lewis (A Pragmatic Conception of the A Priori [1923], p.373)
|
|
A reaction:
[compressed] This simply IS Quine's famous 'web of belief' picture, showing how firmly Quine is in the pragmatist tradition. Lewis treats a priori principles as a pragmatic toolkit, which can be refined to be more effective. Not implausible...

All actions come from: body, lower self, perception, means of action, or Fate [Anon (Bhag)]
|
|
Full Idea:
Whatever a man does, good or bad, in thought, word or deed, has these five sources of action: the body, the lower 'I am', the means of perception, the means of action, and Fate.
|
|
From:
Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 18.14/15)
|
|
A reaction:
The 'means of action' will presumably take care of anything we haven't thought of! Nothing quite matches the idea of 'the will' here. A twitch from the first, eating from the second, a startled jump from the third, struck by lightning from the fifth.

Right and wrong concerns what other people cannot reasonably reject [Scanlon]
|
|
Full Idea:
Thinking about right and wrong is, at the most basic level, thinking about what could be justified to others on grounds that they, if appropriately motivated, could not reasonably reject.
|
|
From:
Thomas M. Scanlon (What We Owe to Each Other [1998], Intro)
|
|
A reaction:
The tricky bit is that the acceptance by others must be 'reasonable', so we need a reasonably objective view of rationality. Don't picture your neighbours, picture the locals when you are on holiday in a very different culture. Other Nazis?

The visible forms of nature are earth, water, fire, air, ether; mind, reason, and the sense of 'I' [Anon (Bhag)]
|
|
Full Idea:
The visible forms of nature are eight: earth, water, fire, air, ether; the mind, reason, and the sense of 'I'.
|
|
From:
Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 7.4)
|
|
A reaction:
Presumably there is an implication that there are also invisible forms. The Bhuddists launched an attack on 'I' as one of the categories. The first five appear to be Aristotle's, which must be of scholarly (and chronological) interest.

Science seeks classification which will discover laws, essences, and predictions [Lewis,CI]
|
|
Full Idea:
The scientific search is for such classification as will make it possible to correlate appearance and behaviour, to discover law, to penetrate to the "essential nature" of things in order that behaviour may become predictable.
|
|
From:
C.I. Lewis (A Pragmatic Conception of the A Priori [1923], p.368)
|
|
A reaction:
Modern scientific essentialists no longer invoke scare quotes, and I think we should talk of the search for the 'mechanisms' which explain behaviour, but Lewis seems to have been sixty years ahead of his time.

Only by love can men see me, know me, and come to me, says Krishna [Anon (Bhag)]
|
|
Full Idea:
Only by love can men see me, and know me, and come unto me, says Krishna
|
|
From:
Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 11.54)
|
|
A reaction:
There seems to be a paradox here, as it is unclear how you can love Krishna, if you have not already seen him in some way. This is another paradox of fideism - that faith cannot possibly be the first step in a religion, as faith needs a target.

The three gates of hell are lust, anger and greed [Anon (Bhag)]
|
|
Full Idea:
Three are the gates of this hell, the death of the soul: the gate of lust, the gate of wrath, and the gate of greed. Let a man shun the three.
|
|
From:
Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 16.21)
|
|
A reaction:
Anyone who wishes to procreate, champion justice, and make a living, has to pursue all three. Wisdom consists of pursuing the three appropriately, not in shunning them. How did this bizarre puritanism ever come to grip the human race?
