9. Objects / D. Essence of Objects / 1. Essences of Objects
13432 The essence of a circle is the equality of its radii [Leibniz]
     Full Idea: The essence of a circle consists in the equality of all lines drawn from its centre to its circumference.
     From: Gottfried Leibniz (Letters to Thomasius [1669], 1669)
     A reaction: Compare Locke in Idea 13431 and Spinoza in Idea 13073 on the essence of geometrical figures. A key question is whether the essence is in the simplest definition, or in a complex and wide-ranging account, e.g. including conic sections for circles.
13. Knowledge Criteria / E. Relativism / 2. Knowledge as Convention
1556 By nature people are close to one another, but culture drives them apart [Hippias]
     Full Idea: I regard you all as relatives - by nature, not by convention. By nature like is akin to like, but convention is a tyrant over humankind and often constrains people to act contrary to nature.
     From: Hippias (fragments/reports [c.430 BCE]), quoted by Plato - Protagoras 337c8
16. Persons / A. Concept of a Person / 4. Persons as Agents
9758 To make sense of personal identity, focus on agency rather than experience [Korsgaard]
     Full Idea: A focus on agency makes more sense of personal identity than a focus on experience.
     From: Christine M. Korsgaard (Intro to 'Creating the Kingdom of Ends' [1996], §2)
     A reaction: This strikes me as eminently sensible advice for the beginning of any discussion of personal identity. Her personal bęte noir is Parfit, who focuses on what we are conscious of.
9757 A person viewed as an agent makes no sense without its own future [Korsgaard]
     Full Idea: In forming a particular plan of life, you need to identify with your future in order to be what you are even now. When the person is viewed as an agent, no clear content can be given to the idea of a merely present self.
     From: Christine M. Korsgaard (Intro to 'Creating the Kingdom of Ends' [1996], §2)
     A reaction: I certainly like the notion that we should treat persons primarily as agents, since I take personhood to be more like a process than an existent entity. If a large brick is about to hit you, you actually have no future, though you think you have.
20. Action / A. Definition of Action / 1. Action Theory
9759 Theory of action focuses on explanation and prediction; practical action on justification and choice [Korsgaard]
     Full Idea: When we look at our actions from the theoretical standpoint our concern is with their explanation and prediction. When we view them from the practical standpoint our concern is with their justification and choice.
     From: Christine M. Korsgaard (Intro to 'Creating the Kingdom of Ends' [1996], §4)
     A reaction: A nice distinction, which invites us to further subdivide action theory into two branches, with entirely different concerns.
22. Metaethics / B. Value / 2. Values / i. Self-interest
9760 Self-concern may be a source of pain, or a lack of self-respect, or a failure of responsibility [Korsgaard]
     Full Idea: For utilitarians, self-concern causes needless pain; for Kantians, it evinces a lack of respect for one's own humanity; for the religious moralist, it is a failure of responsibility for what has been placed in one's special care.
     From: Christine M. Korsgaard (Intro to 'Creating the Kingdom of Ends' [1996], §5)
     A reaction: Worryingly, given my heathenish views, I find the third one the most congenial. If we don't take responsibility for our own selves (e.g. for having a great talent), then no one (even parents) will take responsibility for anything.
23. Ethics / A. Egoism / 1. Ethical Egoism
9761 Personal concern for one's own self widens out into concern for the impersonal [Korsgaard]
     Full Idea: The personal concern which begins with one's life in a particular body finds its place in ever-widening spheres of agency and enterprise, developing finally into a personal concern for the impersonal.
     From: Christine M. Korsgaard (Intro to 'Creating the Kingdom of Ends' [1996], §5)
     A reaction: I am very struck by this nice thought, which comes from a very committed Kantian. It seems to me to capture the modern orthodoxy in ethical thinking - that concern for one's self, rather than altruism, is central, but altruism should follow from it.
27. Natural Reality / A. Classical Physics / 1. Mechanics / a. Explaining movement
12696 Bodies are recreated in motion, and don't exist in intervening instants [Leibniz]
     Full Idea: I have demonstrated that whatever moves is continuously created and that bodies are nothing at any time between the instants in motion.
     From: Gottfried Leibniz (Letters to Thomasius [1669], 1669.04), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 1
     A reaction: Leibniz is a little over-confident about what he has 'demonstrated', but I think (from this remark) that he would not have been displeased with quantum theory, and the notion of a 'quantum leap' and a 'Planck time'. A 'conatus' is a 'smallest motion'.
