Because something does exist, there must be a drive in possible things towards existence [Leibniz]
|
|
Full Idea:
From the very fact that something exists rather than nothing, we recognise that there is in possible things, that is, in the very possibility or essence, a certain exigent need of existence, and, so to speak, some claim to existence.
|
|
From:
Gottfried Leibniz (On the Ultimate Origination of Things [1697], p.347)
|
|
A reaction:
I love the fact that Leibniz tried to explain why there is something rather than nothing. Bede Rundle and Dale Jacquette are similar heroes. As Leibniz tells us, contradictions have no claim to existence, but non-contradictions do.

The world is physically necessary, as its contrary would imply imperfection or moral absurdity [Leibniz]
|
|
Full Idea:
Although the world is not metaphysically necessary, such that its contrary would imply a contradiction or logical absurdity, it is necessary physically, that is, determined in such a way that its contrary would imply imperfection or moral absurdity.
|
|
From:
Gottfried Leibniz (On the Ultimate Origination of Things [1697], p.139)
|
|
A reaction:
How does Leibniz know things like this? The distinction between 'metaphysical' necessity and 'natural' (what he calls 'physical') necessity is a key idea. But natural necessity is controversial. See 'Essentialism'.

Happiness is not satisfaction of desires, but fulfilment of values [Bradley, by Scruton]
|
|
Full Idea:
For Bradley, the happiness of the individual is not to be understood in terms of his desires and needs, but rather in terms of his values - which is to say, in terms of those of his desires which he incorporates into his self.
|
|
From:
report of F.H. Bradley (Ethical Studies [1876]) by Roger Scruton - Short History of Modern Philosophy Ch.16
|
|
A reaction:
Good. Bentham will reduce the values to a further set of desires, so that a value is a complex (second-level?) desire. I prefer to think of values as judgements, but I like Scruton's phrase of 'incorporating into his self'. Kant take note (Idea 1452).

Democracy is competition for support of the people, guided by self-interest on all sides [Posner]
|
|
Full Idea:
Democratic politics is a competition among self-interested politicians, constituting a ruling class, for the support of the people, also assumed to be self-interested, and none too interested or well informed about politics.
|
|
From:
Richard Posner (Law, Pragmatism and Democracy [2003], p.144), quoted by Andrew Shorten - Contemporary Political Theory 05
|
|
A reaction:
This articulates the 'competitive' view of democracy, as simply a technique for establishing legitimacy. Posner is also an economist, and they also assume that everyone is wholly self-interested, which may be why they are so frequently wrong.

The principle of determination in things obtains the greatest effect with the least effort [Leibniz]
|
|
Full Idea:
There is always in things a principle of determination which is based on consideration of maximum and minimum, such that the greatest effect is obtained with the least, so to speak, expenditure.
|
|
From:
Gottfried Leibniz (On the Ultimate Origination of Things [1697], p.347)
|
|
A reaction:
This is obvious in human endeavours. Leibniz applied it to physics, producing a principle that shortest paths are always employed. It has a different formal name in modern physics, I think. He says if you make an unrestricted triangle, it is equilateral.
