Stephen Schiffer’s paradox of meaning shows that both Fregean and Russellian explanations of the individuals in thoughts-propositions are questionable. The author argues that it is Pavel Tichý’s semantical system, which offers a viable middle way between the extremes of the above mentioned approaches, solving the Schiffer’s paradox.

This paper follows in Pavel Tichý’s concept of distinguishing between trivial (i.e. constant) and non-trivial properties. This classification has been extended by Pavel Cmorej who distinguished two kinds of non-trivial properties, namely purely empirical and partly essential (which are partly empirical) properties (partly essential property is essential for certain individual(s), but that it is not for other(s)). The present study provides rigorous formal definitions of trivial / non-trivial, essential / non-essential, and purely empirical / partly essential / purely essential properties (...) with respect to the possible partiality of these properties. In addition, a definition of trivially void properties completing the classification of the kinds of properties to form a quadruplet is proposed. Furthermore, the introduction of the concept of accidental properties gives rise to another (yet not equivalent) quadruplet: purely accidental / partly essential (i.e. partly accidental) / purely essential / void properties.

A bare individual was conceived by Tichý as an individual such as if the property the individual instantiates is non-trivial , it is possible for the individual to lack it ; and for any trivial property that it cannot lack this kind of property. The exact readings of Tichý’s original formulations of are subjected to a detailed analysis to reveal that any of them is refutable by means of Cmorejian objection that there exist contingent properties which are partly essential . (...) To avoid such objection, the present paper attempts to rebuild Tichý’s definitions into viable ones. (shrink)
