A poker, for instance, is just a poker; we do not call one "John" and another "Peter."
The distinction between the class of objects denoted by such a word and the class of objects denoted by a general name such as "man," "vegetable," or "planet," is that the sort of object which is an instance of (say) "lightning" is much simpler than (say) an individual man.
Let us take as an instance the telling of some remembered event.
Of course there is no guaranteeing (this is my comment) that it will not be, for instance
, frightfully dull then (for what will one have to do when everything will be calculated and tabulated), but on the other hand everything will be extraordinarily rational.
For instance, 'white' being present in a body is predicated of that in which it is present, for a body is called white: the definition, however, of the colour white' is never predicable of the body.
For instance, if the characteristic 'terrestrial' is predicated of the species 'man', the definition also of that characteristic may be used to form the predicate of the species 'man': for 'man' is terrestrial.
Take, for an instance, this description of high-northern summer:--
"The New Endymion" is a good instance of such sustained  power.
The captain, at Mr Allworthy's instance, was outwardly, as we have said, reconciled to his brother; yet the same rancour remained in his heart; and he found so many opportunities of giving him private hints of this, that the house at last grew insupportable to the poor doctor; and he chose rather to submit to any inconveniences which he might encounter in the world, than longer to bear these cruel and ungrateful insults from a brother for whom he had done so much.
The doctor went directly to London, where he died soon after of a broken heart; a distemper which kills many more than is generally imagined, and would have a fair title to a place in the bill of mortality, did it not differ in one instance from all other diseases--viz., that no physician can cure it.
In animals it has a more marked effect; for instance, I find in the domestic duck that the bones of the wing weigh less and the bones of the leg more, in proportion to the whole skeleton, than do the same bones in the wild-duck; and I presume that this change may be safely attributed to the domestic duck flying much less, and walking more, than its wild parent.
Nevertheless, as our varieties certainly do occasionally revert in some of their characters to ancestral forms, it seems to me not improbable, that if we could succeed in naturalising, or were to cultivate, during many generations, the several races, for instance, of the cabbage, in very poor soil (in which case, however, some effect would have to be attributed to the direct action of the poor soil), that they would to a large extent, or even wholly, revert to the wild aboriginal stock.
