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. |
8921 | Structuralism is now common, studying relations, with no regard for what the objects might be [Hellman] |
Full Idea: With developments in modern mathematics, structuralist ideas have become commonplace. We study 'abstract structures', having relations without regard to the objects. As Hilbert famously said, items of furniture would do. | |
From: Geoffrey Hellman (Structuralism [2007], §1) | |
A reaction: Hilbert is known as a Formalist, which suggests that modern Structuralism is a refined and more naturalist version of the rather austere formalist view. Presumably the sofa can't stand for six, so a structural definition of numbers is needed. |
8922 | Maybe mathematical objects only have structural roles, and no intrinsic nature [Hellman] |
Full Idea: There is the tantalizing possibility that perhaps mathematical objects 'have no nature' at all, beyond their 'structural role'. | |
From: Geoffrey Hellman (Structuralism [2007], §1) | |
A reaction: This would fit with a number being a function rather than an object. We are interested in what cars do, not the bolts that hold them together? But the ontology of mathematics is quite separate from how you do mathematics. |
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. |
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. |
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. |
16713 | Philosophers are the forefathers of heretics [Tertullian] |
Full Idea: Philosophers are the forefathers of heretics. | |
From: Tertullian (works [c.200]), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 20.2 |
6610 | I believe because it is absurd [Tertullian] |
Full Idea: I believe because it is absurd ('Credo quia absurdum est'). | |
From: Tertullian (works [c.200]), quoted by Robert Fogelin - Walking the Tightrope of Reason n4.2 | |
A reaction: This seems to be a rather desperate remark, in response to what must have been rather good hostile arguments. No one would abandon the support of reason if it was easy to acquire. You can't deny its engaging romantic defiance, though. |
