Species and genera are individual concepts which naturally signify many individuals [William of Ockham]
|
|
Full Idea:
In his mature nominalism, species and genera are identified with certain mental qualities called concepts or intentions of the mind. Ontologically they are individuals too, like everthing else, ...but they naturally signify many different individuals.

From:
William of Ockham (works [1335]), quoted by Claude Panaccio - William of Ockham p.1056
|
|
A reaction:
'Naturally' is the key word, because the concepts are not fictions, but natural responses to encountering individuals in the world. I am an Ockhamist.

I could take a healthy infant and train it up to be any type of specialist I choose [Watson,JB]
|
|
Full Idea:
Give me a dozen healthy infants, and my own specified world to bring them up in, and I'll guarantee to take any one at random and train him to become any type of specialist I might select - doctor, artist, beggar, thief - regardless of his ancestry.

From:
J.B. Watson (Behaviorism [1924], Ch.2), quoted by Steven Pinker - The Blank Slate
|
|
A reaction:
This was a famous pronouncement rejecting the concept of human nature as in any way fixed - a total assertion of nurture over nature. Modern research seems to be suggesting that Watson is (alas?) wrong.

The past has ceased to exist, and the future does not yet exist, so time does not exist [William of Ockham]
|
|
Full Idea:
Time is composed of non-entities, because it is composed of the past which does not exist now, although it did exist, and of the future, which does not yet exist; therefore time does not exist.

From:
William of Ockham (works [1335], 6:496), quoted by Richard T.W. Arthur - Leibniz 7 'Nominalist'
|
|
A reaction:
I've a lot of sympathy with this! I favour Presentism, so the past is gone and the future is yet to arrive. But we have no coherent concept of a present moment of any duration to contain reality. We are just completely bogglificated by it all.
