… tu ne sais pas de quoi tu parles…

It is a rather curious fact in philosophy that the data which are undeniable to start with are always rather vague and ambiguous. You can, for instance, say: “There are a number of people in this room at this moment.” That is obviously in some sense undeniable. But when you come to try and define what this room is, and what it is for a person to be in a room, and how you are going to distinguish one person from another, and so forth, you find that what you have said is most fearfully vague and that you really do not know what you meant.

…nous ne savons presque jamais de quoi nous parlons…

Science is knowledge which we understand so well that we can teach it to a computer; and if we don’t fully understand something, it is an art to deal with it. Since the notion of an algorithm or a computer program provides us with an extremely useful test for the depth of our knowledge about any given subject, the process of going from an art to a science means that we learn how to automate something.

Mais comment faire pour le savoir un petit peu?

[…] the greater potential is for computers as modeling machines, not knowledge jukeboxes. McCarty, Willard. 2005. Humanities Computing. Paperback edition. Palgrave Macmillan.

La réponse est donc : le modèle!

Mais qu’est-ce qu’un modèle?

  • modèle représentationnel
  • fonctionnel
  • physique

ou alors…

Double fente

Thomas Young, 1801: is the light a wave or a set of particles?

Bohr argued that if we were to perform a two-slit experiment with a which-path device (which can be used to determine which slit each electron goes through on its way to the detecting screen), we would find that the interference pattern is destroyed. That is, if a measurement is made that identifies the electron as a particle, as is the case when we use a which-path detector, then the result will be a particle pattern, not the wave pattern that results when the original unmodified two-slit apparatus is used. Karen Barad, Meeting the Universe halfway, p. 103

Les concepts sont des arrangement physiques spécifiques

Bohr’s argument for the indeterminable nature of measurement interactions is based on his insight that concepts are defined by the circumstances required for their measurement. That is, theoretical concepts are not ideational in character; they are specific physical arrangements. Karen Barad, Meeting the Universe halfway, p. 109

Heisenberg vs Bohr

Incertitude vs indétermination

Le modèle est une configuration matérielle spécifique

  • Le modèle est la matérialité des concepts
  • Le modèle n’est pas une représentation du réel.
  • En dehors du modèle, il n’y a pas une réalité plus “réelle” mais insaisissable, mais juste une réalité indéterminée.
