The term ontology (from Greek to on, ontos—being, entity; logos—concept, science) usually denotes: (a) a philosophical discipline that studies being (entity) as being (entity), that is, being in general; (b) the ontology of a theory: the kind of entities that should exist if the given theory is true.

One of the fundamental problems of ontology (particularly in its first meaning) is the question about the relation between being and becoming and thus the question about the place and role of time in the explanation of reality.

As a philosophical discipline, ontology has existed at least since the time of Aristotle (384–322 BCE), who in his Metaphysics claims that one of its tasks is to investigate “being as being and the attributes that belong to this in virtue of its own nature.”

Truthlikeness

Truth is the aim of inquiry. Despite this, progress in an inquiry does not always consist in supplanting falsehoods with truths. The history of science is replete with cases of falsehoods supplanting other falsehoods.

If such transitions are to constitute epistemic progress, then it must be possible for one falsehood better to realize the aim of inquiry—be more truthlike, be closer to the truth, or have more verisimilitude—than another. The notion of “truthlikeness” is thus fundamental for any theory of knowledge that endeavors to take our epistemic limitations seriously without embracing epistemic pessimism.

Given that truthlikeness is not only a much-needed notion but rich and interesting, it is surprising that it has attracted less attention than the simpler notion of truth. The explanation is twofold. First, if knowledge requires truth, then falsehoods cannot constitute knowledge. The high value of knowledge has obscured other epistemic values such as the comparative value of acquiring more truthlike theories.

Ehrenfried Walter von Tschirnhaus (or Tschirnhausen), the German mathematician and physicist, was born in Kieslingswalde, near Görlitz, and became count of Kieslingswalde and Stolzenberg. He studied mathematics at Görlitz and at the University of Leiden, where the Cartesian philosophers Adriaan Heereboord and Arnold Geulincx were teaching.

After serving with the Dutch in 1672 during a war with France, Tschirnhaus studied further in Leiden and in Germany, and in 1674 he traveled to London, Paris, Rome, Sicily, and Malta. He met Benedict de Spinoza in Holland, English scientists in London, and he undoubtedly met Cartesian philosophers and scientists such as Jacques Rohault and Pierre-Sylvain Régis in Paris.

Tschirnhaus finally settled down in Kieslingswalde. He established several factories for manufacturing glass and for grinding magnifying glasses, and was associated with J. F. Böttger in the development of Meissen porcelain.
