| 17962 | The truth-maker principle is that every truth has a sufficient truth-maker [Forrest] |
| Full Idea: Item x is said to be a sufficient truth-maker for truth-bearer p just in case necessarily if x exists then p is true. ...Every truth has a sufficient truth-maker. Hence, I take it, the sum of all sufficient truth-makers is a universal truth-maker. | |
| From: Peter Forrest (General Facts,Phys Necessity, and Metaph of Time [2006], 1) | |
| A reaction: Note that it is not 'necessary', because something else might make p true instead. |
| 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. |
| 23834 | Friendship is partly universal - the love of a person is like the ideal of loving everyone [Weil] |
| Full Idea: Friendship has something universal about it. It consists in loving a human being as we should like to be able to love each soul in particular of all those who go to make up the human race. | |
| From: Simone Weil (Friendship [1940], p.288) | |
| A reaction: Hm. Would you like your lover to dream of loving the human race, rather than just loving you? Perhaps only a Christian could see friendship in this way? |
| 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]) |
