A monad and its body are living, so life is everywhere, and comes in infinite degrees [Leibniz]
|
|
Full Idea:
Each monad, together with a particular body, makes up a living substance. Thus, there is not only life everywhere, joined to limbs or organs, but there are also infinite degrees of life in the monads, some dominating more or less over others.
|
|
From:
Gottfried Leibniz (Principles of Nature and Grace based on Reason [1714], 4)
|
|
A reaction:
Two key ideas: that each monad is linked to a body (which is presumably passive), and the infinite degrees of life in monads. Thus rocks consist of monads, but at an exceedingly low degree of life. They are stubborn and responsive.

Days exist, and yet they seem to be made up of parts which don't exist [Burley]
|
|
Full Idea:
I grant that a successive being is composed out of non-beings, as is clear of a day, which is composed of non-entities. Some part of this day is past and some future, and yet this day is.

From:
Walter Burley (Commentary on 'Physics' [1325], III text 11,f.65rb), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 18.3
|
|
A reaction:
The dilemma of Aristotle over time infected the scholastic attempt to give an account of successive entities. A day is a wonderfully elusive entity for a metaphysician.

Unlike permanent things, successive things cannot exist all at once [Burley]
|
|
Full Idea:
This is the difference between permanent and successive things: that a permanent thing exists all at once, or at least can exist all at once, whereas it is incompatible with a successive thing to exist all at once.
|
|
From:
Walter Burley (Commentary on 'Physics' [1325], III txt 11,f.65rb), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 18.1
|
|
A reaction:
Permanent things sound like what are now called 'three-dimensional' objects, but scholastic 'entia successiva' are not the same as spacetime 'worms' or collections of temporal stages.

'Perception' is basic internal representation, and 'apperception' is reflective knowledge of perception [Leibniz]
|
|
Full Idea:
We distinguish between 'perception', the internal state of the monad representing external things, and 'apperception', which is consciousness, or the reflective knowledge of this internal state, not given to all souls, nor at all times to a given soul.
|
|
From:
Gottfried Leibniz (Principles of Nature and Grace based on Reason [1714], §4)
|
|
A reaction:
The word 'apperception' is standard in Kant. I find it surprising that modern analytic philosophers don't seem to use it when they write about perception. It strikes me as useful, but maybe specialists have a reason for avoiding it.

Animals are semi-rational because they connect facts, but they don't see causes [Leibniz]
|
|
Full Idea:
There is a connexion between the perceptions of animals, which bears some resemblance to reason: but it is based only on the memory of facts or effects, and not at all on the knowledge of causes.
|
|
From:
Gottfried Leibniz (Principles of Nature and Grace based on Reason [1714], §5)
|
|
A reaction:
This amounts to the view that animals can do Humean induction (where you see regularities), but not Leibnizian induction (where you see necessities). I say all minds perceive patterns, but only humans can think about the patterns they have perceived.
