experiri and experimentum and thereby also speaks of quantities, modern science begins already in the Middle Ages.
If take that tack, then back to the source of this medieval "modernity": Aristotle, ἐμπειρία.
Now experimentation opposed to experiri. In the postulation of nature as a nexus of the "existence" of things according to laws, the notions of harmonia mundi and of ordo, κόσμος [order, world"], play a co-determining role, though they become ever more withdrawn.
Basic conditions of the possibility of modern experimentation:
1. the mathematical projection of nature; objectification; representedness.
2. transformation of the essence of actuality from essentiality to individuality. Only under this presupposition can an individual result claim the power to establish something and to verify it.
79. Exact science and experimentation
1. In what sense does exact science require experimentation?
2. Prior question: what is an experiment?
Experiri and experimentation
3. Show how, within natural science, "experiments" are different in their character according to the respective objectivity and according to their mode of interrogating. The purely measuring experiment.
4. A "psychological" experiment.
5. A "biological" experiment.
A "psychological" experiment
Discussed not in order to show what an experiment is (also this) but to show another direction and level of objectification.
Now to look at what? Facts
Not at what? and
What distinction? laws
For what and why this "experiment"?
In what nexus of questioning does it stand?
80. Experiri—experientia—experimentum—"experimentation"
Experiencing, striking up against something, something strikes me, I have undergone experiences, "bad" ones.
