5 ideas
| 13095 | Essence is primitive force, or a law of change [Leibniz] |
| Full Idea: The essence of substances consists in the primitive force of action, or the law of the sequence of changes. | |
| From: Gottfried Leibniz (Letters to Foucher [1675], 1676) | |
| A reaction: [a 1676 note on Foucher's reply] It take these to be the two key distinctive Leibnizian contributions to the sort of metaphysic that is needed by modern science. Nature works with intrinsic essences, which are forces determining action. |
| 468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
| Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
| From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
| 22442 | If lies were ever acceptable, with would undermine all duties based on contract [Kant] |
| Full Idea: Truthfulness is a duty that must be regarded as the basis of all duties to be grounded on a contract, the law of which is made uncertain and useless if even the least exception to it is admitted. | |
| From: Immanuel Kant (On a supposed right to lie [1797], p.30) | |
| A reaction: Should we keep contracts which are made by means of deception and coercion? Where could such absolute authority for contracts come from? Do contracts and treaties tend to lapse after a long period of time? |
| 22441 | The law will protect you if you tell a truth which results in murder [Kant] |
| Full Idea: If you have by a lie prevented someone bent on murder from committing the deed, then you are legally accountable for all the consequences that might arise from it. But if you keep strictly to the truth, then public justice can hold nothing against you. | |
| From: Immanuel Kant (On a supposed right to lie [1797], p.29) | |
| A reaction: Shocking, from a supposedly great thinker. Cowardly hiding behind a perverse law. What would Kant do if the law were changed, to condemn someone who told a truth which would probably lead to a murder? Would he accept a jail sentence? |
| 2117 | The connection in events enables us to successfully predict the future, so there must be a constant cause [Leibniz] |
| Full Idea: There is a connection among our appearances that provides us the means to predict future appearances with success, and this connection must have a constant cause. | |
| From: Gottfried Leibniz (Letters to Foucher [1675]) |
