16665 | There are entities, and then positive 'modes', modifying aspects outside the thing's essence [Suárez] |
Full Idea: Beyond the entities there are certain real 'modes', which are positive, and in their own right act on those entities, giving them something that is outside their whole essence as individuals existing in reality. | |
From: Francisco Suárez (Disputationes metaphysicae [1597], 7.1.17), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 13.3 | |
A reaction: Suárez is apparently the first person to formulate a proper account of properties as 'modes' of a thing, rather than as accidents which are separate, or are wholly integrated into a thing. A typical compromise proposal in philosophy. Can modes act? |
16666 | A mode determines the state and character of a quantity, without adding to it [Suárez] |
Full Idea: The inherence of quantity is called its mode, because it affects that quantity, which serves to ultimately determine the state and character of its existence, but does not add to it any new proper entity, but only modifies the preexisting entity. | |
From: Francisco Suárez (Disputationes metaphysicae [1597], 7.1.17), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 13.3 | |
A reaction: He seems to present mode as a very active thing, like someone who gives it a coat of paint, or hammers it into a new shape. I don't see how a 'mode' can have any ontological status at all. To exist, there has to be some way to exist. |
16667 | Substances are incomplete unless they have modes [Suárez, by Pasnau] |
Full Idea: In the view of Suárez, substances are radically incomplete entities that cannot exist at all until determined in various ways by things of another kind, modes. …Modes are regarded as completers for their subjects. | |
From: report of Francisco Suárez (Disputationes metaphysicae [1597]) by Robert Pasnau - Metaphysical Themes 1274-1671 13.3 | |
A reaction: This is correct. In order to be a piece of clay it needs a shape, a mass, a colour etc. Treating clay as an object independently from its shape is a misunderstanding. |
17007 | Forms must rule over faculties and accidents, and are the source of action and unity [Suárez] |
Full Idea: A form is required that, as it were, rules over all those faculties and accidents, and is the source of all actions and natural motions of such a being, and in which the whole variety of accidents and powers has its root and unity. | |
From: Francisco Suárez (Disputationes metaphysicae [1597], 15.1.7), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 24.4 | |
A reaction: Pasnau emphasises that this is scholastics giving a very physical and causal emphasis to forms, which made them vulnerable to doubts among the new experiment physicists. Pasnau says forms are 'metaphysical', following Leibniz. |
16780 | Partial forms of leaf and fruit are united in the whole form of the tree [Suárez] |
Full Idea: In a tree the part of the form that is in the leaf is not the same character as the part that is in the fruit., but yet they are partial forms, and apt to be united ….to compose one complete form of the whole. | |
From: Francisco Suárez (Disputationes metaphysicae [1597], 15.10.30), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 26.6 | |
A reaction: This is a common scholastic view, the main opponent of which was Aquinas, who says each thing only has one form. Do leaves have different DNA from the bark or the fruit? Presumably not (since I only have one DNA), which supports Aquinas. |
16758 | The best support for substantial forms is the co-ordinated unity of a natural being [Suárez] |
Full Idea: The most powerful arguments establishing substantial forms are based on the necessity, for the perfect constitution of a natural being, that all the faculties and operations of that being are rooted in one essential principle. | |
From: Francisco Suárez (Disputationes metaphysicae [1597], 15.10.64), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 24.4 | |
A reaction: Note Idea 15756, that this stability not only applies to biological entities (the usual Aristotelian examples), but also to non-living natural kinds. We might say that the drive for survival is someone united around a single entity. |
16743 | We can get at the essential nature of 'quantity' by knowing bulk and extension [Suárez] |
Full Idea: We can say that the form that gives corporeal bulk [molem] or extension to things is the essential nature of quantity. To have bulk is to expel a similar bulk from the same space. | |
From: Francisco Suárez (Disputationes metaphysicae [1597], 40.4.16), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 539 | |
A reaction: This is one step away from asking why, once we knew the bulk and extension of the thing, we would still have any interest in trying to grasp something called its 'quantity'. |
16742 | We only know essences through non-essential features, esp. those closest to the essence [Suárez] |
Full Idea: We can almost never set out the essences of things, as they are in things. Instead, we work through their connection to some non-essential feature, and we seem to succeed well enough when we spell it out through the feature closest to the essence. | |
From: Francisco Suárez (Disputationes metaphysicae [1597], 40.4.16), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 23.5 | |
A reaction: It is a common view that with geometrical figures we can actually experience the essence itself. So has science broken through, and discerned actual essences of things? |
22143 | Identity does not exclude possible or imagined difference [Suárez, by Boulter] |
Full Idea: To be really the same excludes being really other, but does not exclude being other modally or mentally. | |
From: report of Francisco Suárez (Disputationes metaphysicae [1597], 7.65) by Stephen Boulter - Why Medieval Philosophy Matters 4 | |
A reaction: So the statue and the clay are identical, but they could become separate, or be imagined as separate. |
22144 | Real Essential distinction: A and B are of different natural kinds [Suárez, by Boulter] |
Full Idea: The Real Essential distinction says if A and B are not of the same natural kind, then they are essentially distinct. This is the highest degree of distinction. | |
From: report of Francisco Suárez (Disputationes metaphysicae [1597], Bk VII) by Stephen Boulter - Why Medieval Philosophy Matters 4 | |
A reaction: Boulter says Peter is essentially distinct from a cabbage, because neither has the nature of the other. |
22146 | Minor Real distinction: B needs A, but A doesn't need B [Suárez, by Boulter] |
Full Idea: The Minor Real distinction is if A can exist without B, but B ceases to exist without A. | |
From: report of Francisco Suárez (Disputationes metaphysicae [1597], Bk VII) by Stephen Boulter - Why Medieval Philosophy Matters 4 | |
A reaction: This is one-way independence. Boulter's example is Peter and Peter's actual weight. |
22145 | Major Real distinction: A and B have independent existences [Suárez, by Boulter] |
Full Idea: The Major Real distinction is if A can exist in the real order without B, and B can exist in the real order without A. | |
From: report of Francisco Suárez (Disputationes metaphysicae [1597], Bk VII) by Stephen Boulter - Why Medieval Philosophy Matters 4 | |
A reaction: Boulter's example is the distinction between Peter and Paul, where their identity of kind is irrelevant. This is two-way independence. |
22147 | Conceptual/Mental distinction: one thing can be conceived of in two different ways [Suárez, by Boulter] |
Full Idea: The Conceptual or Mental distinction is when A and B are actually identical but we have two different ways of conceiving them. | |
From: report of Francisco Suárez (Disputationes metaphysicae [1597], Bk VII) by Stephen Boulter - Why Medieval Philosophy Matters 4 | |
A reaction: This is the Morning and Evening Star. I bet Frege never read Suarez. This seems to be Spinoza's concept of mind/body. |
22148 | Modal distinction: A isn't B or its property, but still needs B [Suárez, by Boulter] |
Full Idea: The Modal distinction is when A is not B or a property of B, but still could not possibly exist without B. | |
From: report of Francisco Suárez (Disputationes metaphysicae [1597], Bk VII) by Stephen Boulter - Why Medieval Philosophy Matters 4 | |
A reaction: Duns Scotus proposed in, Ockham rejected it, but Suarez supports it. Suarez proposes that light's dependence on the Sun is distinct from the light itself, in this 'modal' way. |
22149 | Scholastics assess possibility by what has actually happened in reality [Suárez, by Boulter] |
Full Idea: The scholastic view is that Actuality is our only guide to possibility in the real order. One knows that it is possible to separate A and B if one knows that A and B have actually been separated or are separate. | |
From: report of Francisco Suárez (Disputationes metaphysicae [1597], Bk VII) by Stephen Boulter - Why Medieval Philosophy Matters 4 | |
A reaction: It may be possible to separate A and B even though it has never happened, but it is hard to see how we could know that. (But if I put my pen down where it has never been before, I know I can pick it up again, even though this has not previously happened). |
2584 | Lobotomised patients can cease to care about a pain [Block] |
Full Idea: After frontal lobotomies, patients typically report that they still have pains, though the pains no longer bother them. | |
From: Ned Block (Troubles with Functionalism [1978], p. 83) | |
A reaction: I take this to be an endorsement of reductive physicalism, because what matters about pains is that they bother us, not how they feel, so frog pain could do the job, if it felt different from ours, but was disliked by the frog. |
2582 | A brain looks no more likely than anything else to cause qualia [Block] |
Full Idea: NO physical mechanism seems very intuitively plausible as a seat of qualia, least of all a brain. | |
From: Ned Block (Troubles with Functionalism [1978], p. 78) | |
A reaction: I'm not sure about "least of all", given the mind-boggling complexity of the brain's connections. Certainly, though, nothing in either folk physics or academic physics suggests that any physical object is likely to be aware of anything. |
2574 | Behaviour requires knowledge as well as dispositions [Block] |
Full Idea: A desire cannot be identified with a disposition to act, since the agent might not know that a particular act leads to the thing desired, and thus might not be disposed to do it. | |
From: Ned Block (Troubles with Functionalism [1978], p. 69) | |
A reaction: One might have a disposition to act, but not in a particular way. "Something must be done". To get to the particular act, it seems that indeed a belief must be added to the desire. |
2575 | Functionalism is behaviourism, but with mental states as intermediaries [Block] |
Full Idea: Functionalism is a new incarnation of behaviourism, replacing sensory inputs with sensory inputs plus mental states, and replacing dispositions to act with dispositions plus certain mental states. | |
From: Ned Block (Troubles with Functionalism [1978], p. 69) | |
A reaction: I think of functionalism as behaviourism which extends inside the 'black box' between stimulus and response. It proposes internal stimuli and responses. Consequently functionalism inherits some behaviourist problems. |
2576 | In functionalism, desires are internal states with causal relations [Block] |
Full Idea: According to functionalism, a system might have the behaviouristic input-output relations, yet not desire something, as this requires internal states with certain causal relations. | |
From: Ned Block (Troubles with Functionalism [1978], p. 69) | |
A reaction: Such a system might be Putnam's 'superactor', who only behaves as if he desires something. Of course, the internal states might need more than just 'causal relations'. |
2583 | You might invert colours, but you can't invert beliefs [Block] |
Full Idea: It is hard to see how to make sense of the analog of color spectrum inversion with respect to non-qualitative states such a beliefs (where they are functionally equivalent but have different beliefs). | |
From: Ned Block (Troubles with Functionalism [1978], p. 81) | |
A reaction: I would suggest that beliefs can be 'inverted', because there are all sorts of ways to implement a belief, but colour can't be inverted, because that depends on a particular brain state. It makes good sense to me... |
2578 | Could a creature without a brain be in the right functional state for pain? [Block] |
Full Idea: If pain is a functional state, it cannot be a brain state, because creatures without brains could realise the same Turing machine as creatures with brains. | |
From: Ned Block (Troubles with Functionalism [1978], p. 70) | |
A reaction: This strikes me as being a poorly grounded claim. There may be some hypothetical world where brainless creatures implement all our functions, but from here brains look the only plausible option. |
2585 | Not just any old functional network will have mental states [Block] |
Full Idea: If there are any fixed points in the mind-body problem, one of them is that the economy of Bolivia could not have mental states, no matter how it is distorted. | |
From: Ned Block (Troubles with Functionalism [1978], p. 86) | |
A reaction: It is hard to disagree with this, but then it can hardly be a serious suggestion that anyone could see how to reconfigure an economy so that it mapped the functional state of the human brain. This is not a crucial problem. |
2586 | In functionalism, what are the special inputs and outputs of conscious creatures? [Block] |
Full Idea: In functionalism, it is very hard to see how there could be a single physical characterization of the inputs and outputs of all and only creatures with mentality. | |
From: Ned Block (Troubles with Functionalism [1978], p. 87) | |
A reaction: It would be theoretically possible if the only way to achieve mentality was to have a particular pattern of inputs and outputs. I don't think, though, that 'mentality' is an all-or-nothing concept. |
2579 | Physicalism is prejudiced in favour of our neurology, when other systems might have minds [Block] |
Full Idea: Physicalism is a chauvinist theory: it withholds mental properties from systems that in fact have them. | |
From: Ned Block (Troubles with Functionalism [1978], p. 71) | |
A reaction: This criticism interprets physicalism too rigidly. There may be several ways to implement a state. My own view is that other systems might implement our functions, but they won't experience them in a human way. |
2577 | Simple machine-functionalism says mind just is a Turing machine [Block] |
Full Idea: In the simplest Turing-machine version of functionalism (Putnam 1967), mental states are identified with the total Turing-machine state, involving a machine table and its inputs and outputs. | |
From: Ned Block (Troubles with Functionalism [1978], p. 70) | |
A reaction: This obviously invites the question of why mental states would be conscious and phenomenal, given that modern computers are devoid of same, despite being classy Turing machines. |
2580 | A Turing machine, given a state and input, specifies an output and the next state [Block] |
Full Idea: In a Turing machine, given any state and input, the machine table specifies an output and the next state. …To have full power the tape must be infinite in at least one direction, and be movable in both directions. | |
From: Ned Block (Troubles with Functionalism [1978], p. 71) | |
A reaction: In retrospect, the proposal that this feeble item should be taken as a model for the glorious complexity and richness of human consciousness doesn't look too plausible. |
2581 | Intuition may say that a complex sentence is ungrammatical, but linguistics can show that it is not [Block] |
Full Idea: Linguistics rejects (on theoretical grounds) the intuition that the sentence "the boy the girl the cat bit scratched died" is ungrammatical. | |
From: Ned Block (Troubles with Functionalism [1978], p. 78) | |
A reaction: Once we have disentangled it, we practical speakers have no right to say it is ungrammatical. It isn't only theory. The sentence is just stylistically infelicitous. |
18225 | If we can't reason about value, we can reason about the unconditional source of value [Korsgaard] |
Full Idea: If you can only know what is intrinsically valuable through intuition (as Moore claims), you can still argue about what is unconditionally valuable. There must be something unconditionally valuable because there must be a source of value. | |
From: Christine M. Korsgaard (Aristotle and Kant on the Source of Value [1986], 8 'Three') | |
A reaction: If you only grasped the values through intuition, does that give you enough information to infer the dependence relations between values? |
18228 | An end can't be an ultimate value just because it is useless! [Korsgaard] |
Full Idea: If what is final is whatever is an end but never a means, ...why should something be more valuable just because it is useless? | |
From: Christine M. Korsgaard (Aristotle and Kant on the Source of Value [1986], 8 'Finality') | |
A reaction: Korsgaard is offering this as a bad reading of what Aristotle intends. |
18224 | Goodness is given either by a psychological state, or the attribution of a property [Korsgaard] |
Full Idea: 'Subjectivism' identifies good ends with or by reference to some psychological state. ...'Objectivism' says that something is good as an end if a property, intrinsic goodness, is attributed to it. | |
From: Christine M. Korsgaard (Aristotle and Kant on the Source of Value [1986], 8 'Three') | |
A reaction: Not sure about 'objectivism' here, as attributing a 'property'. A tomato is not intrinsically good. Hopeless for building walls. |
18233 | Contemplation is final because it is an activity which is not a process [Korsgaard] |
Full Idea: It is because contemplation is an activity that is not also a process that Aristotle identifies it as the most final good. | |
From: Christine M. Korsgaard (Aristotle and Kant on the Source of Value [1986], 8 'Activity') | |
A reaction: Quite a helpful way of labelling what Aristotle has in mind. So should we not aspire to be involved in processes, except reluctantly? I take the mind itself to be a process, so that may be difficult! |
18226 | For Aristotle, contemplation consists purely of understanding [Korsgaard] |
Full Idea: Contemplation, as Aristotle understand it, is not research or inquiry, but an activity that ensues on these: an activity that consists in understanding. | |
From: Christine M. Korsgaard (Aristotle and Kant on the Source of Value [1986], 8 'Aristotle') | |
A reaction: Fairly obvious, when you read the last part of 'Ethics', but helpful in grasping Aristotle, because understanding is the objective of 'Posterior Analytics' and 'Metaphysics', so he tells you how to achieve the ideal moral state. |
16682 | Other things could occupy the same location as an angel [Suárez] |
Full Idea: An angelic substance could be penetrated by other bodies in the same location. | |
From: Francisco Suárez (Disputationes metaphysicae [1597], 40.2.21), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 15.3 | |
A reaction: So am I co-located with an angel right now? |
