3798 | An overexamined life is as bad as an unexamined one [Dennett] |
Full Idea: The unexamined life may not be worth living, but the overexamined life is nothing to write home about either. | |
From: Daniel C. Dennett (Elbow Room: varieties of free will [1984], §4.2) | |
A reaction: Presumably he means a life which is all theory and no practice. Compare Idea 343. |
3801 | Rationality requires the assumption that things are either for better or worse [Dennett] |
Full Idea: We must assume that something matters - that some things are for better and some things are for worse, for without that our assumed rationality would have nothing on which to get a purchase. | |
From: Daniel C. Dennett (Elbow Room: varieties of free will [1984], §7.1) | |
A reaction: It does seem that rationality wouldn't exist as an activity without some value to motivate it. |
3035 | Dialectic involves conversations with short questions and brief answers [Diog. Laertius] |
Full Idea: Dialectic is when men converse by putting short questions and giving brief answers to those who question them. | |
From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 3.1.52) |
18946 | Unreflectively, we all assume there are nonexistents, and we can refer to them [Reimer] |
Full Idea: As speakers of the language, we unreflectively assume that there are nonexistents, and that reference to them is possible. | |
From: Marga Reimer (The Problem of Empty Names [2001], p.499), quoted by Sarah Sawyer - Empty Names 4 | |
A reaction: Sarah Swoyer quotes this as a good solution to the problem of empty names, and I like it. It introduces a two-tier picture of our understanding of the world, as 'unreflective' and 'reflective', but that seems good. We accept numbers 'unreflectively'. |
3802 | Why pronounce impossible what you cannot imagine? [Dennett] |
Full Idea: You say you cannot imagine that p, and therefore declare that p is impossible. Mightn't that be hubris? | |
From: Daniel C. Dennett (Elbow Room: varieties of free will [1984], §7.3) |
1816 | Sceptics say demonstration depends on self-demonstrating things, or indemonstrable things [Diog. Laertius] |
Full Idea: Sceptics say that every demonstration depends on things which demonstrates themselves, or on things which can't be demonstrated. | |
From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 9.Py.11) | |
A reaction: This refers to two parts of Agrippa's Trilemma (the third being that demonstration could go on forever). He makes the first option sound very rationalist, rather than experiential. |
3795 | Causal theories require the "right" sort of link (usually unspecified) [Dennett] |
Full Idea: In causal theories of knowledge and reference, the causal chain between object and thought must be of the "right" sort - the nature of rightness to be specified later, typically. | |
From: Daniel C. Dennett (Elbow Room: varieties of free will [1984], §3.3 n14) | |
A reaction: This is now the standard objection to a purely causal account of reference. Which of the many causal chains causes the meaning? Knowledge of maths is a further problem for it. |
1819 | Scepticism has two dogmas: that nothing is definable, and every argument has an opposite argument [Diog. Laertius] |
Full Idea: Sceptics actually assert two dogmas: that nothing should be defined, and that every argument has an opposite argument. | |
From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 9.Py.11) |
3064 | When sceptics say that nothing is definable, or all arguments have an opposite, they are being dogmatic [Diog. Laertius] |
Full Idea: When sceptics say that they define nothing, and that every argument has an opposite argument, they here give a positive definition, and assert a positive dogma. | |
From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 9.11.11) |
3033 | Induction moves from some truths to similar ones, by contraries or consequents [Diog. Laertius] |
Full Idea: Induction is an argument which by means of some admitted truths establishes naturally other truths which resemble them; there are two kinds, one proceeding from contraries, the other from consequents. | |
From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 3.1.23) |
3797 | I am the sum total of what I directly control [Dennett] |
Full Idea: Control is the ultimate criterion of the self: I am the sum total of the parts I control directly. | |
From: Daniel C. Dennett (Elbow Room: varieties of free will [1984], §4.2) | |
A reaction: This looks awfully like a flagrant self-contradiction, and I think it is. It seems pretty obvious that there is at least a distinction between the bit or bits that do the controlling, and the bits that get controlled. |
3800 | You can be free even though force would have prevented you doing otherwise [Dennett, by PG] |
Full Idea: If a brain implant would compel you to perform an action which you in fact freely choose, then you are free, but couldn't have done otherwise. | |
From: report of Daniel C. Dennett (Elbow Room: varieties of free will [1984], §6.1) by PG - Db (ideas) |
3803 | Can we conceive of a being with a will freer than our own? [Dennett] |
Full Idea: Can I even conceive of beings whose wills are freer than our own? | |
From: Daniel C. Dennett (Elbow Room: varieties of free will [1984], §7.3) |
3791 | Awareness of thought is a step beyond awareness of the world [Dennett] |
Full Idea: The creature who is not only sensitive to patterns in its environment, but also sensitive to patterns in its own reactions to patterns in its environment, has taken a major step. | |
From: Daniel C. Dennett (Elbow Room: varieties of free will [1984], §2.2) |
3794 | Foreknowledge permits control [Dennett] |
Full Idea: Foreknowledge is what permits control. | |
From: Daniel C. Dennett (Elbow Room: varieties of free will [1984], §3.2) |
3796 | The active self is a fiction created because we are ignorant of our motivations [Dennett] |
Full Idea: Faced with our inability to 'see' where the centre or source of our free actions is,…we exploit the gaps in our self-knowledge by filling it with a mysterious entity, the unmoved mover, the active self. | |
From: Daniel C. Dennett (Elbow Room: varieties of free will [1984], §4.1) | |
A reaction: I am convinced that there is no such things as free will; its origins are to be found in religion, where it is a necessary feature of a very supreme God. I don't believe for a moment that we need to believe in free will. |
1838 | Cyrenaic pleasure is a motion, but Epicurean pleasure is a condition [Diog. Laertius] |
Full Idea: Cyrenaics place pleasure wholly in motion, whereas Epicurus admits it as a condition. | |
From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 10.28) | |
A reaction: Not a distinction we meet in modern discussions. Do events within the mind count as 'motion'? If so, these two agree. If not, I'd vote for Epicurus. |
1769 | Cynics believe that when a man wishes for nothing he is like the gods [Diog. Laertius] |
Full Idea: Cynics believe that when a man wishes for nothing he is like the gods. | |
From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 6.Men.3) |
