Gareth evans’s argument against vague identity

Vague Existence Implies Vague Identity

Vague parts and vague identity

We propose that not all such arguments are on a par. The first section of the paper distinguishes dialectically effective from dialectically ineffective arguments against metaphysical vagueness. The second section constructs an argument against metaphysical vagueness – specifically, an argument against objects that are indeterminate in what parts they have – which promises to be dialectically e...

Against the Vagueness Argument

In this paper I offer a counterexample to the so called vagueness argument against restricted composition. This will be done in the lines of a recent suggestion by Trenton Merricks, namely by challenging the claim that there cannot be a sharp cut-off point in a composition sequence. It will be suggested that causal powers which emerge when composition occurs can serve as an indicator of such sh...

An Argument against Epiphenomenalism

_________________________________________________ I formulate an argument against epiphenomenalism; the argument shows that epiphenomenalism is extremely improbable. Moreover the argument suggests that qualia not only have causal powers, but have their causal powers necessarily. I address possible objections and then conclude by considering some implications the argument has for dualism.

Argument on biometrics identity-based encryption schemes

Recently, a few biometric identity-based encryption (BIO-IBE) schemes have been proposed. BIO-IBE leverages both fuzzy extractor and Lagrange polynomial to extract biometric feature as a user public key and as a preventive measure of collusion attack, respectively. In this paper, we reveal that BIO-IBE is not realistic whereby a query of fresh biometrics is needed for each encryption process. M...
