Vagueness as closeness

This paper presents and defends a definition of vagueness, compares it favourably with alternative definitions, and draws out some consequences of accepting this definition for the project of offering a substantive theory of vagueness. The definition is roughly this: a predicate ‘F’ is vague just in case for any objects a and b, if a and b are very close in respects relevant to the possession of F, then ‘Fa’ and ‘Fb’ are very close in respect of truth. The definition is extended to cover vagueness of many-place predicates, of properties and relations, and of objects. Some of the most important advantages of the definition are that it captures the intuitions which motivate the thought that vague predicates are tolerant, without leading to contradiction, and that it yields a clear understanding of the relationships between higher-order vagueness, sorites susceptibility, blurred boundaries, and borderline cases. The most notable consequence of the definition is that the correct theory of vagueness must countenance degrees of truth.     

Examining foster care: A viable solution for placement of handicapped children?

Foster care for handicapped children has become a frequently used and even more frequently criticized procedure. Traditional methods of foster placement have resulted in a number of negative outcomes, especially for the placed children. Based on a review of some recent innovative foster care programs, this paper has isolated a number of options for the restructuring of the entire foster care delivery system. These options include: rigorous client evaluation, use of selection and training criteria for foster parents, matching of client needs to caregiver abilities in making placement decisions, and ongoing professional support and supervision after placement. Systematic consideration of these issues may help make foster care a more viable solution to the growing problem of home placement for handicapped children.
