12124 | Metaphysics is the best knowledge, because it is the simplest [Bacon] |
Full Idea: That knowledge is worthiest which is charged with least multiplicity, which appeareth to be metaphysic | |
From: Francis Bacon (The Advancement of Learning [1605], II.VII.6) | |
A reaction: A surprising view, coming from the father of modern science, but essentially correct. Obviously metaphysics aspires to avoid multiplicity, but it is riddled not only with complexity in its researches, but massive uncertainties. |
12123 | Natural history supports physical knowledge, which supports metaphysical knowledge [Bacon] |
Full Idea: Knowledges are as pyramides, whereof history is the basis. So of natural philosophy, the basis is natural history, the stage next the basis is physic; the stage next the vertical point is metaphysic. | |
From: Francis Bacon (The Advancement of Learning [1605], II.VII.6) | |
A reaction: The father of modern science keeps a place for metaphysics, as the most abstract level above the physical sciences. I would say he is right. It leads to my own slogan: science is the servant of philosophy. |
12119 | Physics studies transitory matter; metaphysics what is abstracted and necessary [Bacon] |
Full Idea: Physic should contemplate that which is inherent in matter, and therefore transitory; and metaphysic that which is abstracted and fixed | |
From: Francis Bacon (The Advancement of Learning [1605], II.VII.3) | |
A reaction: He cites the ancients for this view, with which he agrees. One could do worse than hang onto metaphysics as the study of necessities, but must then face the attacks of the Quineans - that knowledge of necessities is beyond us. |
12120 | Physics is of material and efficient causes, metaphysics of formal and final causes [Bacon] |
Full Idea: Physic inquireth and handleth the material and efficient causes; and metaphysic handleth the formal and final causes. | |
From: Francis Bacon (The Advancement of Learning [1605], II.VII.3) | |
A reaction: Compare Idea 12119. This divides up Aristotle's famous Four Causes (or Explanations), outlined in 'Physics' II.3. The concept of 'matter', and the nature of 'cause' seem to me to fall with the purview of metaphysics. Interesting, though. |
8443 | Mereological essentialism says an entity must have exactly those parts [Sosa] |
Full Idea: Mereological essentialism says that nothing else could have been the unique entity composed of certain parts except the very thing that is composed of those parts. | |
From: Ernest Sosa (Varieties of Causation [1980], 2) | |
A reaction: This sounds initially implausible. It means the ship of Theseus ceases to be that ship if you change a single nail of it. Whether we say that seems optional, but if we do, it leads to the collaps of all our normal understanding of identity. |
12121 | We don't assume there is no land, because we can only see sea [Bacon] |
Full Idea: They are ill discoverers that think there is no land, when they can see nothing but sea. | |
From: Francis Bacon (The Advancement of Learning [1605], II.VII.5) | |
A reaction: Just the sort of pithy remark for which Bacon is famous. It is an obvious point, but a nice corrective to anyone who wants to apply empirical principles in a rather gormless way. |
12117 | Science moves up and down between inventions of causes, and experiments [Bacon] |
Full Idea: All true and fruitful natural philosophy hath a double scale or ladder, ascendent and descendent, ascending from experiments to the invention of causes, and descending from causes to the invention of new experiments. | |
From: Francis Bacon (The Advancement of Learning [1605], II.VII.1) | |
A reaction: After several hundred years, I doubt whether anyone can come up with a better account of scientific method than Bacon's. |
12127 | Many different theories will fit the observed facts [Bacon] |
Full Idea: The ordinary face and view of experience is many times satisfied by several theories and philosophies. | |
From: Francis Bacon (The Advancement of Learning [1605], II.VIII.5) | |
A reaction: He gives as his example that the Copernican system and the Ptolemaic system both seem to satisfy all the facts. He wrote in 1605, just before Galileo's telescope. His point is regularly made in modern discussions. In this case, he was wrong! |
12126 | People love (unfortunately) extreme generality, rather than particular knowledge [Bacon] |
Full Idea: It is the nature of the mind of man (to the extreme prejudice of knowledge) to delight in the spacious liberty of generalities, as in a champaign region, and not in the inclosures of particularity. | |
From: Francis Bacon (The Advancement of Learning [1605], II.VIII.1) | |
A reaction: I have to plead guilty to this myself. He may have pinpointed the key motivation behind philosophy. We all want to know things, as Aristotle said, but some of us want the broad brush, and others want the fine detail. |
22352 | Out of more than a hundred planets, Earth is the only one with the idea of free will [Vonnegut] |
Full Idea: I wouldn’t have any idea what was meant by ‘free will'. I’ve visited thirty-one inhabited planets in the universe, and studied reports on one hundred more. Only on Earth is there any talk of free will. | |
From: Kurt Vonnegut (Slaughterhouse Five [1969], Ch.4) | |
A reaction: Spoken by the ambassador from the planet Tralfamadore. Possibly the greatest put down of a philosophical idea since Diogenes responded to Plato's definition of a man. I think free will is a non-idea. It is non-sensical, and doesn't exist. |
12125 | Teleological accounts are fine in metaphysics, but they stop us from searching for the causes [Bacon] |
Full Idea: To say 'leaves are for protecting of fruit', or that 'clouds are for watering the earth', is well inquired and collected in metaphysic, but in physic they are impertinent. They are hindrances, and the search of the physical causes hath been neglected. | |
From: Francis Bacon (The Advancement of Learning [1605], II.VII.7) | |
A reaction: This is the standard rebellion against Aristotle which gave rise to the birth of modern science. The story has been complicated by natural selection, which bestows a sort of purpose on living things. Nowadays we pursue both paths. |
8442 | What law would explain causation in the case of causing a table to come into existence? [Sosa] |
Full Idea: If I fasten a board onto a tree stump, causing a table to come into existence, ...what law of nature or, even, what quasi-law or law-like principle could possibly play in such a case of generation the role required by nomological accounts? | |
From: Ernest Sosa (Varieties of Causation [1980], 1) | |
A reaction: A very nice question. The nomological account is at its strongest when rocks fall off walls or magnets attract, but all sorts of other caused events seem too messy or complex or original to fit the story. |
8444 | Where is the necessary causation in the three people being tall making everybody tall? [Sosa] |
Full Idea: It is not clear how to analyse the form of necessary causation found in the only three people in the room being tall causing everybody in the room to be tall. | |
From: Ernest Sosa (Varieties of Causation [1980], 5) | |
A reaction: I would want to challenge this as a case of causation. There are no events or processes involved. It seems that a situation described in one way can also be described in another. |
8445 | The necessitated is not always a result or consequence of the necessitator [Sosa] |
Full Idea: The necessitated is not always a result or consequence of the necessitator. If p-and-q is a fact, then this necessitates that p, but the fact that p need not be a result or consequence of the fact that p-and-q. | |
From: Ernest Sosa (Varieties of Causation [1980], p.242) | |
A reaction: This is obviously correct, and needs to be borne in mind when considering necessary causation. It is not enough to produce a piece of logic; something in the link from cause to effect must be demonstrated to be necessary. |
12118 | Essences are part of first philosophy, but as part of nature, not part of logic [Bacon] |
Full Idea: I assign to summary philosophy the operation of essences (as quantity, similitude, diversity, possibility), with this distinction - that they be handled as they have efficacy in nature, and not logically. | |
From: Francis Bacon (The Advancement of Learning [1605], II.VII.3) | |
A reaction: I take this to be a splendid motto for scientific essentialism, in a climate where modal logicians appear to have taken over the driving seat in our understanding of essences. |
