Entailment is logical requirement; it may be not(p and not-q), but that has problems [Mautner]
5. Theory of Logic / B. Logical Consequence / 7. Strict Implication
Strict implication says false propositions imply everything, and everything implies true propositions [Mautner]
5. Theory of Logic / B. Logical Consequence / 8. Material Implication
'Material implication' is defined as 'not(p and not-q)', but seems to imply a connection between p and q [Mautner]
A person who 'infers' draws the conclusion, but a person who 'implies' leaves it to the audience [Mautner]

Counterfactuals are not true, they are merely valid [Mautner]
Counterfactuals are true if in every world close to actual where p is the case, q is also the case [Mautner]

Observing lots of green x can confirm 'all x are green' or 'all x are grue', where 'grue' is arbitrary [Mautner, by PG]
14. Science / C. Induction / 5. Paradoxes of Induction / b. Raven paradox
'All x are y' is equivalent to 'all non-y are non-x', so observing paper is white confirms 'ravens are black' [Mautner, by PG]

Persons are conscious, they relate, they think, they feel, and they are self-aware [Glover]

A problem arises in any moral system that allows more than one absolute right [Glover]
20. Action / C. Motives for Action / 5. Action Dilemmas / b. Double Effect
Double Effect: no bad acts with good consequences, but possibly good acts despite bad consequences [Glover]
Double effect is the distinction between what is foreseen and what is intended [Mautner]
Double effect acts need goodness, unintended evil, good not caused by evil, and outweighing [Mautner]
20. Action / C. Motives for Action / 5. Action Dilemmas / c. Omissions
Acts and Omissions: bad consequences are morally better if they result from an omission rather than an act [Glover]

Harmful omissions are unavoidable, while most harmful acts can be avoided [Glover]
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / e. Human nature
'Essentialism' is opposed to existentialism, and claims there is a human nature [Mautner]

What matters is not intrinsic value of life or rights, but worthwhile and desired life, and avoidance of pain [Glover]
22. Metaethics / B. Value / 2. Values / e. Death
'Death' is best seen as irreversible loss of consciousness, since this is why we care about brain function [Glover]

Satisfaction of desires is not at all the same as achieving happiness [Glover, by PG]

Rule-utilitarianism is either act-utilitarianism, or not really utilitarian [Glover]
24. Political Theory / A. Basis of a State / 2. Population / a. Human population
How can utilitarianism decide the ideal population size? [Glover]
The sanctity of life doctrine implies a serious increase of abnormality among the population [Glover]
24. Political Theory / D. Ideologies / 6. Liberalism / g. Liberalism critique
Autonomy favours present opinions over future ones, and says nothing about the interests of potential people [Glover]
If a whole community did not mind death, respect for autonomy suggests that you could kill them all [Glover]
25. Social Practice / A. Freedoms / 5. Freedom of lifestyle
Autonomy seems to acquire greater weight when the decision is more important to a person [Glover]
25. Social Practice / C. Rights / 2. Moral rights
Being alive is not intrinsically good, and there is no 'right to life' [Glover]
You can't have a right to something you can't desire, so a foetus has no 'right' to life [Glover]
25. Social Practice / F. Life Issues / 1. Causing Death
If someone's life is 'worth living', that gives one direct reason not to kill him [Glover]
Utilitarians object to killing directly (pain, and lost happiness), and to side-effects (loss to others, and precedents) [Glover]
What is wrong with killing someone, if another equally worthwhile life is substituted? [Glover]
The 'no trade-off' position: killing is only justified if it prevents other deaths [Glover]
Societies spend a lot to save known persons, but very little to reduce fatal accidents [Glover]
25. Social Practice / F. Life Issues / 2. Euthanasia
Involuntary euthanasia is wrong because it violates autonomy, and it has appalling side-effects [Glover]
Euthanasia is voluntary (patient's wish), or involuntary (ignore wish), or non-voluntary (no wish possible) [Glover]
Maybe extreme treatment is not saving life, but prolonging the act of dying [Glover]
The Nazi mass murders seem to have originated in their euthanasia programme [Glover]
25. Social Practice / F. Life Issues / 3. Abortion
If killing is wrong because it destroys future happiness, not conceiving a happy child is also wrong [Glover]
Defenders of abortion focus on early pregnancy, while opponents focus on later stages [Glover]
If abortion is wrong, it is because a foetus is a human being or a person (or potentially so) [Glover]
If abortion is wrong because of the 'potential' person, that makes contraception wrong too [Glover]
Abortion differs morally from deliberate non-conception only in its side-effects [Glover]
If viability is a test or boundary at the beginning of life, it should also be so for frail old people [Glover]
Apart from side effects, it seems best to replace an inadequate foetus with one which has a better chance [Glover]
It is always right for a qualified person to perform an abortion when requested by the mother [Glover]
Conception isn't the fixed boundary for a person's beginning, because twins are possible within two weeks [Glover]
How would we judge abortion if mothers had transparent wombs? [Glover]
25. Social Practice / F. Life Issues / 4. Suicide
One test for a worthwhile life is to assess the amount of life for which you would rather be unconscious [Glover]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / c. Ultimate substances
Thales said water is the first principle, perhaps from observing that food is moist [Thales, by Aristotle]
27. Natural Reality / A. Classical Physics / 1. Mechanics / a. Explaining movement
Thales must have thought soul causes movement, since he thought magnets have soul [Thales, by Aristotle]
29. Religion / A. Polytheistic Religion / 2. Greek Polytheism
Thales said the gods know our wrong thoughts as well as our evil actions [Thales, by Diog. Laertius]
