2. Reason / A. Nature of Reason / 4. Aims of Reason
Good inference has mechanism, precision, scope, simplicity, fertility and background fit [Lipton]
2. Reason / A. Nature of Reason / 9. Limits of Reason
All reasoning endlessly leads to further reasoning (Mode 12) [Agrippa, by Diog. Laertius]
Reasoning needs arbitrary faith in preliminary hypotheses (Mode 14) [Agrippa, by Diog. Laertius]
All discussion is full of uncertainty and contradiction (Mode 11) [Agrippa, by Diog. Laertius]
Proofs often presuppose the thing to be proved (Mode 15) [Agrippa, by Diog. Laertius]
2. Reason / B. Laws of Thought / 4. Contraries
Contrary pairs entail contradictions; one member entails negation of the other [Lipton]
11. Knowledge Aims / A. Knowledge / 2. Understanding
Understanding is not mysterious - it is just more knowledge, of causes [Lipton]
13. Knowledge Criteria / A. Justification Problems / 2. Justification Challenges / a. Agrippa's trilemma
Agrippa's Trilemma: justification is infinite, or ends arbitrarily, or is circular [Agrippa, by Williams,M]
13. Knowledge Criteria / B. Internal Justification / 3. Evidentialism / a. Evidence
How do we distinguish negative from irrelevant evidence, if both match the hypothesis? [Lipton]
13. Knowledge Criteria / E. Relativism / 1. Relativism
Everything is perceived in relation to another thing (Mode 13) [Agrippa, by Diog. Laertius]
14. Science / A. Basis of Science / 1. Observation
The inference to observables and unobservables is almost the same, so why distinguish them? [Lipton]
14. Science / A. Basis of Science / 2. Demonstration
We infer from evidence by working out what would explain that evidence [Lipton]
Inductive inference is not proof, but weighing evidence and probability [Lipton]
14. Science / A. Basis of Science / 4. Prediction
It is more impressive that relativity predicted Mercury's orbit than if it had accommodated it [Lipton]
Predictions are best for finding explanations, because mere accommodations can be fudged [Lipton]
14. Science / B. Scientific Theories / 1. Scientific Theory
If we make a hypothesis about data, then a deduction, where does the hypothesis come from? [Lipton]
14. Science / C. Induction / 1. Induction
Induction is repetition, instances, deduction, probability or causation [Lipton]
14. Science / C. Induction / 3. Limits of Induction
Standard induction does not allow for vertical inferences, to some unobservable lower level [Lipton]
14. Science / C. Induction / 4. Reason in Induction
We can argue to support our beliefs, so induction will support induction, for believers in induction [Lipton]
An inductive inference is underdetermined, by definition [Lipton]
14. Science / C. Induction / 5. Paradoxes of Induction / b. Raven paradox
If something in ravens makes them black, it may be essential (definitive of ravens) [Lipton]
My shoes are not white because they lack some black essence of ravens [Lipton]
A theory may explain the blackness of a raven, but say nothing about the whiteness of shoes [Lipton]
We can't turn non-black non-ravens into ravens, to test the theory [Lipton]
To pick a suitable contrast to ravens, we need a hypothesis about their genes [Lipton]
14. Science / C. Induction / 6. Bayes's Theorem
A hypothesis is confirmed if an unlikely prediction comes true [Lipton]
Bayes seems to rule out prior evidence, since that has a probability of one [Lipton]
Bayes is too liberal, since any logical consequence of a hypothesis confirms it [Lipton]
Bayes involves 'prior' probabilities, 'likelihood', 'posterior' probability, and 'conditionalising' [Lipton]
Explanation may be an important part of implementing Bayes's Theorem [Lipton]
14. Science / D. Explanation / 1. Explanation / a. Explanation
Explanation may describe induction, but may not show how it justifies, or leads to truth [Lipton]
14. Science / D. Explanation / 1. Explanation / b. Aims of explanation
An explanation gives the reason the phenomenon occurred [Lipton]
An explanation is what makes the unfamiliar familiar to us [Lipton]
An explanation is what is added to knowledge to yield understanding [Lipton]
Seaching for explanations is a good way to discover the structure of the world [Lipton]
14. Science / D. Explanation / 2. Types of Explanation / b. Contrastive explanations
In 'contrastive' explanation there is a fact and a foil - why that fact, rather than this foil? [Lipton]
With too many causes, find a suitable 'foil' for contrast, and the field narrows right down [Lipton]
14. Science / D. Explanation / 2. Types of Explanation / c. Explanations by coherence
An explanation unifies a phenomenon with our account of other phenomena [Lipton]
14. Science / D. Explanation / 2. Types of Explanation / e. Lawlike explanations
Deduction explanation is too easy; any law at all will imply the facts - together with the facts! [Lipton]
We reject deductive explanations if they don't explain, not if the deduction is bad [Lipton]
Good explanations may involve no laws and no deductions [Lipton]
14. Science / D. Explanation / 2. Types of Explanation / f. Necessity in explanations
An explanation shows why it was necessary that the effect occurred [Lipton]
14. Science / D. Explanation / 2. Types of Explanation / g. Causal explanations
Causal inferences are clearest when we can manipulate things [Lipton]
To explain is to give either the causal history, or the causal mechanism [Lipton]
Mathematical and philosophical explanations are not causal [Lipton]
A cause may not be an explanation [Lipton]
Explanations may be easier to find than causes [Lipton]
14. Science / D. Explanation / 2. Types of Explanation / i. Explanations by mechanism
We want to know not just the cause, but how the cause operated [Lipton]
14. Science / D. Explanation / 2. Types of Explanation / l. Probabilistic explanations
To maximise probability, don't go beyond your data [Lipton]
14. Science / D. Explanation / 3. Best Explanation / a. Best explanation
Is Inference to the Best Explanation nothing more than inferring the likeliest cause? [Lipton]
Best Explanation as a guide to inference is preferable to best standard explanations [Lipton]
The 'likeliest' explanation is the best supported; the 'loveliest' gives the most understanding [Lipton]
Finding the 'loveliest' potential explanation links truth to understanding [Lipton]
IBE is inferring that the best potential explanation is the actual explanation [Lipton]
IBE is not passive treatment of data, but involves feedback between theory and data search [Lipton]
A contrasting difference is the cause if it offers the best explanation [Lipton]
We select possible explanations for explanatory reasons, as well as choosing among them [Lipton]
14. Science / D. Explanation / 3. Best Explanation / c. Against best explanation
Must we only have one explanation, and must all the data be made relevant? [Lipton]
Bayesians say best explanations build up an incoherent overall position [Lipton]
The best theory is boring: compare 'all planets move elliptically' with 'most of them do' [Lipton]
Best explanation can't be a guide to truth, because the truth must precede explanation [Lipton]
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / j. Ethics by convention
True goodness is political, and consists of love of and submission to the laws [Montesquieu]
24. Political Theory / A. Basis of a State / 1. A People / b. The natural life
Men do not desire to subjugate one another; domination is a complex and advanced idea [Montesquieu]
Primitive people would be too vulnerable and timid to attack anyone, so peace would reign [Montesquieu]
24. Political Theory / A. Basis of a State / 1. A People / c. A unified people
People are drawn into society by needs, shared fears, pleasure, and knowledge [Montesquieu]
People are guided by a multitude of influences, from which the spirit of a nation emerges [Montesquieu]
24. Political Theory / A. Basis of a State / 2. Population / b. State population
In small republics citizens identify with the public good, and abuses are fewer [Montesquieu]
In a large republic there is too much wealth for individuals to manage it [Montesquieu]
24. Political Theory / A. Basis of a State / 4. Original Position / b. Veil of ignorance
The rich would never submit to a lottery deciding which part of their society should be slaves [Montesquieu]
24. Political Theory / B. Nature of a State / 1. Purpose of a State
All states aim at preservation, and then have distinctive individual purposes [Montesquieu]
24. Political Theory / C. Ruling a State / 2. Leaders / a. Autocracy
The natural power of a father suggests rule by one person, but that authority can be spread [Montesquieu]
24. Political Theory / C. Ruling a State / 2. Leaders / b. Monarchy
The nobility are an indispensable part of a monarchy [Montesquieu]
Monarchs must not just have links to the people; they need a body which maintains the laws [Montesquieu]
Ambition is good in a monarchy, because the monarch can always restrain it [Montesquieu]
In monarchies, men's actions are judged by their grand appearance, not their virtues [Montesquieu]
In a monarchy, the nobility must be hereditary, to bind them together [Montesquieu]
Monarchies can act more quickly, because one person is in charge [Montesquieu]
24. Political Theory / C. Ruling a State / 2. Leaders / c. Despotism
A despot's agents must be given power, so they inevitably become corrupt [Montesquieu]
Despots are always lazy and ignorant, so they always delegate their power to a vizier [Montesquieu]
Despotism and honour are incompatible, because honour scorns his power, and lives by rules [Montesquieu]
Tyranny is either real violence, or the imposition of unpopular legislation [Montesquieu]
The will of a despot is an enigma, so magistrates can only follow their own will [Montesquieu]
24. Political Theory / C. Ruling a State / 2. Leaders / d. Elites
If the nobility is numerous, the senate is the artistocracy, and the nobles are a democracy [Montesquieu]
Aristocracy is democratic if they resemble the people, but not if they resemble the monarch [Montesquieu]
Great inequality between aristocrats and the rest is bad - and also among aristocrats themselves [Montesquieu]
24. Political Theory / C. Ruling a State / 3. Government / a. Government
If a government is to be preserved, it must first be loved [Montesquieu]
A government has a legislature, an international executive, and a domestic executive [Montesquieu]
24. Political Theory / C. Ruling a State / 3. Government / b. Legislature
The judiciary must be separate from the legislature, to avoid arbitrary power [Montesquieu]
24. Political Theory / D. Ideologies / 5. Democracy / b. Consultation
The fundamental laws of a democracy decide who can vote [Montesquieu]
It is basic to a democracy that the people themselves must name their ministers [Montesquieu]
Voting should be public, so the lower classes can be influenced by the example of notable people [Montesquieu]
All citizens (apart from the very humble poor) should choose their representatives [Montesquieu]
24. Political Theory / D. Ideologies / 5. Democracy / c. Direct democracy
In a democracy the people should manage themselves, and only delegate what they can't do [Montesquieu]
A democratic assembly must have a fixed number, to see whether everyone has spoken [Montesquieu]
24. Political Theory / D. Ideologies / 5. Democracy / d. Representative democracy
If deputies represent people, they are accountable, but less so if they represent places [Montesquieu]
25. Social Practice / A. Freedoms / 1. Slavery
Slavery is entirely bad; the master abandons the virtues, and they are pointless in the slave [Montesquieu]
Slaves are not members of the society, so no law can forbid them to run away [Montesquieu]
The demand for slavery is just the masters' demand for luxury [Montesquieu]
25. Social Practice / A. Freedoms / 3. Free speech
Freedom of speech and writing, within the law, is essential to preserve liberty [Montesquieu]
25. Social Practice / A. Freedoms / 5. Freedom of lifestyle
Freedom in society is ability to do what is right, and not having to do what is wrong [Montesquieu]
25. Social Practice / B. Equalities / 1. Grounds of equality
No one even thinks of equality in monarchies and despotism; they all want superiority [Montesquieu]
Equality is not command by everyone or no one, but command and obedience among equals [Montesquieu]
25. Social Practice / B. Equalities / 2. Political equality
Democracy is corrupted by lack of equality, or by extreme equality (between rulers and ruled) [Montesquieu]
25. Social Practice / B. Equalities / 4. Economic equality
Some equality can be achieved by social categories, combined with taxes and poor relief [Montesquieu]
Democracies may sometimes need to restrict equality [Montesquieu]
25. Social Practice / D. Justice / 2. The Law / c. Natural law
Prior to positive laws there is natural equity, of obedience, gratitude, dependence and merit [Montesquieu]
Sensation gives animals natural laws, but knowledge can make them break them [Montesquieu]
25. Social Practice / D. Justice / 3. Punishment / a. Right to punish
The death penalty is permissible, because its victims enjoyed the protection of that law [Montesquieu]
If religion teaches determinism, penalties must be severe; if free will, then that is different [Montesquieu]
25. Social Practice / E. Policies / 1. War / d. Non-combatants
The only right victors have over captives is the protection of the former [Montesquieu]
25. Social Practice / E. Policies / 2. Religion in Society
The clergy are essential to a monarchy, but dangerous in a republic [Montesquieu]
Religion can support the state when the law fails to do so [Montesquieu]
Religion has the most influence in despotic states, and reinforces veneration for the ruler [Montesquieu]
French slavery was accepted because it was the best method of religious conversion [Montesquieu]
25. Social Practice / E. Policies / 5. Education / a. Aims of education
In monarchies education ennobles people, and in despotisms it debases them [Montesquieu]
25. Social Practice / E. Policies / 5. Education / c. Teaching
Teaching is the best practice of the general virtue that leads us to love everyone [Montesquieu]
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
Counterfactual causation makes causes necessary but not sufficient [Lipton]
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / c. Essence and laws
