indiscriminable

Furthermore, MDS makes precise what is meant by being a member of an ordering of determinates: a property is a member of an ordering of determinates if and only if there is a qualitative resemblance route from it to any other determinate in the ordering; a qualitative resemblance route is a span of determinates which is continuous in that points along the span which are sufficiently close are indiscriminable, even though points farther apart are discriminable.
