A wise man has integrity, firmness of will, nobility, consistency, sobriety, patience [Cicero]
|
|
Full Idea:
The wise man does nothing of which he can repent, nothing against his will, does everything nobly, consistently, soberly, rightly, not looking forward to anything as bound to come, is not astonished at any novel occurrence, abides by his own decisions.
|
|
From:
M. Tullius Cicero (Tusculan Disputations [c.44 BCE], V.xxviii)
|
|
A reaction:
Notice that the wise man never exhibits weakness of will (an Aristotelian virtue), and is consistent (as Kant proposed), and is patient (as the Stoics proposed). But Cicero doesn't think he should busy himself maximising happiness.

Saying 'they can become a set' is a tautology, because reference to 'they' implies a collection [Cargile]
|
|
Full Idea:
If the rule is asserted 'Given any well-determined objects, they can be collected into a set by an application of the 'set of' operation', then on the usual account of 'they' this is a tautology. Collection comes automatically with this form of reference.

|
From:
James Cargile (Paradoxes: Form and Predication [1979], p.115), quoted by Oliver,A/Smiley,T - What are Sets and What are they For? Intro
|
|
A reaction:
Is this a problem? Given they are well-determined (presumably implying countable) there just is a set of them. That's what set theory is, I thought. Of course, the iterative view talks of 'constructing' the sets, but the construction looks unstoppable.

Every individual thing which exists has an essence, which is its internal constitution [Locke]
|
|
Full Idea:
I take essences to be in everything that internal constitution or frame for the modification of substance, which God in his wisdom gives to every particular creature, when he gives it a being; and such essences I grant there are in all things that exist.
|
|
From:
John Locke (Letters to Edward Stillingfleet [1695], Letter 1), quoted by Simon Blackburn - Quasi-Realism no Fictionalism
|
|
A reaction:
This is the clearest statement I have found of Locke's commitment to essences, for all his doubts about whether we can know such things. Alexander says (ch.13) Locke was reacting against scholastic essence, as pertaining to species.

|
If it is knowledge, it is certain; if it isn't certain, it isn't knowledge [Locke]
|
|
Full Idea:
What reaches to knowledge, I think may be called certainty; and what comes short of certainty, I think cannot be knowledge.
|
|
From:
John Locke (Letters to Edward Stillingfleet [1695], Letter 2), quoted by Simon Blackburn - Quasi-Realism no Fictionalism
|
|
A reaction:
I much prefer that fallibilist approach offered by the pragmatists. Knowledge is well-supported belief which seems (and is agreed) to be true, but there is a small shadow of doubt hanging over all of it.

How can one mind perceive so many dissimilar sensations? [Cicero]
|
|
Full Idea:
Why is it that, using the same mind, we have perception of things so utterly unlike as colour, taste, heat, smell and sound?
|
|
From:
M. Tullius Cicero (Tusculan Disputations [c.44 BCE], I.xx.47)
|
|
A reaction:
This leaves us with the 'binding problem', of how the dissimilar sensations are pulled together into one field of experience. It is a nice simple objection, though, to anyone who simplistically claims that the mind is self-evidently unified.

|
The soul has a single nature, so it cannot be divided, and hence it cannot perish [Cicero]
|
|
Full Idea:
In souls there is no mingling of ingredients, nothing of two-fold nature, so it is impossible for the soul to be divided; impossible, therefore, for it to perish either; for perishing is like the separation of parts which were maintained in union.
|
|
From:
M. Tullius Cicero (Tusculan Disputations [c.44 BCE], I.xxix.71)
|
|
A reaction:
Cicero knows he is pushing his luck in asserting that perishing is a sort of division. Why can't something be there one moment and gone the next? He appears to be in close agreement with Descartes about being a 'thinking thing'.

|
Like the eye, the soul has no power to see itself, but sees other things [Cicero]
|
|
Full Idea:
The soul has not the power of itself to see itself, but, like the eye, the soul, though it does not see itself, yet discerns other things.
|
|
From:
M. Tullius Cicero (Tusculan Disputations [c.44 BCE], I.xxvii)
|
|
A reaction:
The soul is a complex item which contributes many layers of interpretation to what it sees, so there is scope for parts of the soul seeing other parts. Somewhere in the middle Cicero seems to be right - there is an elusive something we can't get at.

|
Souls contain no properties of elements, and elements contain no properties of souls [Cicero]
|
|
Full Idea:
No beginnings of souls can be found on earth; there is no combination in souls that could be born from earth, nothing that partakes of moist or airy or fiery; for in those elements there is nothing to possess the power of memory, thought, or reflection.
|
|
From:
M. Tullius Cicero (Tusculan Disputations [c.44 BCE], I.xxvi.66)
|
|
A reaction:
Interesting, but I think magnetism is an instructive analogy, which has weird properties which we never perceive in elements (though it is there, buried deep - suggesting panpsychism). Cicero would be disconcerted to find that fire isn't an element.
