| 2922 | All intelligent Romans were Epicureans [Nietzsche] |
| Full Idea: Every mind of any account in the Roman Empire was an Epicurean. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 58) |
| 23520 | Truth has had to be fought for, and normal life must be sacrificed to achieve it [Nietzsche] |
| Full Idea: Truth has had to be fought for every step of the way, almost everything else dear to our hearts, on which our love and our trust in life depend, has had to be sacrificed to it. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 50) | |
| A reaction: This, in one of his final works, seems to contradict every idea that Nietzsche is the high priest of relativism about truth. He (and Foucault) and interested in the social role of truth, but are not so daft as to reject its possibility. |
| 2914 | One must never ask whether truth is useful [Nietzsche] |
| Full Idea: One must never ask whether truth is useful. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], Fore) |
| 19400 | Possibles demand existence, so as many of them as possible must actually exist [Leibniz] |
| Full Idea: From the conflict of all the possibles demanding existence, this at once follows, that there exists that series of things by which as many of them as possible exist. | |
| From: Gottfried Leibniz (Exigency to Exist in Essences [1690], p.91) | |
| A reaction: I'm in tune with a lot of Leibniz, but my head swims with this one. He seems to be a Lewisian about possible worlds - that they are concrete existing entities (with appetites!). Could Lewis include Leibniz's idea in his system? |
| 19401 | God's sufficient reason for choosing reality is in the fitness or perfection of possibilities [Leibniz] |
| Full Idea: The sufficient reason for God's choice can be found only in the fitness (convenance) or in the degree of perfection that the several worlds possess. | |
| From: Gottfried Leibniz (Exigency to Exist in Essences [1690], p.92) | |
| A reaction: The 'fitness' of a world and its 'perfection' seem very different things. A piece of a jigsaw can have wonderful fitness, without perfection. Occasionally you get that sinking feeling with metaphysicians that they just make it up. |
| 18617 | Substances, unlike aggregates, can survive a change of parts [Mumford] |
| Full Idea: Substances can survive a change in their parts in a way that a mere aggregate of parts. | |
| From: Stephen Mumford (Metaphysics: a very short introduction [2012], 3) | |
| A reaction: A simple but very important idea. If we then distinguish between 'substances' and 'aggregates' we get a much clearer grip on things. Is the Ship of Theseus a substance or an aggregate? There is no factual answer to that. What do you want to explain? |
| 18618 | Maybe possibilities are recombinations of the existing elements of reality [Mumford] |
| Full Idea: It has been suggested that we could think of possibilities as recombinations of all the existing elements of reality. | |
| From: Stephen Mumford (Metaphysics: a very short introduction [2012], 8) | |
| A reaction: [Armstrong 1989 is the source] The obvious problem would be that the existence of an entirely different reality would be impossible, if this was all possibility could be. It seems to cramp the style of the possible too much. Are properties elements? |
| 18619 | Combinatorial possibility has to allow all elements to be combinable, which seems unlikely [Mumford] |
| Full Idea: The combinatorial account only works if you allow that the elements are recombinable. ...But could Lincoln really have been green? It seems possible that you could jump to the moon, unless we impose some restrictions. | |
| From: Stephen Mumford (Metaphysics: a very short introduction [2012], 8) | |
| A reaction: Mumford suggests different combination rules for logical and natural possibility. The general objection is that combinatorial possibility is too permissive - which it clearly is. |
| 18620 | Combinatorial possibility relies on what actually exists (even over time), but there could be more [Mumford] |
| Full Idea: Can combinatorial possibility deliver enough possibilities? It uses the existing elements, but there might have been one more particular or one more property. Even extended over time, the elements seem finite, yet there could have been more. | |
| From: Stephen Mumford (Metaphysics: a very short introduction [2012], 8) | |
| A reaction: [compressed] One objection is that the theory allows too much, and now the objection is that it allows too little. Both objections are correct, so that's the end of that. But I admire the attempt to base modality on actuality. |
| 19402 | The actual universe is the richest composite of what is possible [Leibniz] |
| Full Idea: The actual universe is the collection of the possibles which forms the richest composite. | |
| From: Gottfried Leibniz (Exigency to Exist in Essences [1690], p.92) | |
| A reaction: 'Richest' for Leibniz means a maximum combination of existence, order and variety. It's rather like picking the best starting team from a squad of footballers. |
| 2921 | Philosophy grasps the limits of human reason, and values are beyond it [Nietzsche] |
| Full Idea: All the supreme problems of value are beyond human reason. …To grasp the limits of human reason, only this is philosophy. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 55) | |
| A reaction: The single most powerful idea in the writings of Nietzsche. Reason and truth are values. Why do we value philosophy? There is no escaping Nietzsche's question. |
| 20138 | Christianity is at war with the higher type of man, and excommunicates his basic instincts [Nietzsche] |
| Full Idea: Christianity has waged a war to the death against the higher type of man, it has excommunicated all the fundamental instincts of this type. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 05) | |
| A reaction: It seems rather insulting to say that the finest and most dedicated altruism practised by the most admirable Christians is the expression of a 'lower' instinct. |
| 20375 | Virtues must be highly personal; if not, it is merely respect for a concept [Nietzsche] |
| Full Idea: A virtue has to be our invention, our most personal defence and necessity: in any other sense it is merely a danger. What does not condition our life harms it: a virtue merely from a feeling of respect for the concept 'virtue', as Kant desires it, is harm | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], §11) | |
| A reaction: Presumably he sees virtue as the cutting edge of stiffling conventional morality. I'm a bit nervous about embracing highly personal virtues, partly because they might isolate me from my community. I ain't no übermensch. |
| 2915 | Each person should devise his own virtues and categorical imperative [Nietzsche] |
| Full Idea: Each one of us should devise his own virtue, his own categorical imperative. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 11) |
| 2920 | A God who cures us of a head cold at the right moment is a total absurdity [Nietzsche] |
| Full Idea: A God who cures a headcold for us at the right moment is so absurd a God he would have to be abolished even if he existed. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 52) |
| 2917 | Christianity is a revolt of things crawling on the ground against elevated things [Nietzsche] |
| Full Idea: Christianity is a revolt of everything which crawls along the ground against everything which is elevated. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 43) |
| 2918 | The story in Genesis is the story of God's fear of science [Nietzsche] |
| Full Idea: Has the famous story which stands at the beginning of the Bible really been understood - the story of God's mortal terror of science? | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 48) |
| 2919 | 'Faith' means not wanting to know what is true [Nietzsche] |
| Full Idea: 'Faith' means not wanting to know what is true. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 52) |
| 2916 | The great lie of immortality destroys rationality and natural instinct [Nietzsche] |
| Full Idea: The great lie of personal immortality destroys all rationality, all naturalness of instinct. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 43) |
