Autism is a neurodevelopmental disorder featuring severe social and communicative deficits. Cognitive impenetrability is the inability of systems to be affected by an individual’s beliefs and desires. Individuals with autism have delayed performance on "mindreading" tasks. Mindreading is the interpretation of others which enables successful social interactions. This task performance is not correlated with "everyday" social function in autism. These deficits are in contrast with general intelligence and reasoning abilities within the normal range, resistant to cognitive behavioral training, and partially attributable to atypical social predispositions. This suggests individuals with autism perform social tasks differently than typicals. I argue that this mindreading deficit is cognitively impenetrable, then position this deficit within a theoretical framework, enactivism, emphasizing cognitive embodiment and inseparability of social comprehension and action. This framework helps explain the cognitive impenetrability of these social deficits by "locating" failure to penetrate in individuals' failure to properly interact with the environment.

The purpose of this thesis is to compare the personal income tax in the Czech Republic and Slovakia, focusing on the years from 2004 to 2015. The work is divided into two chapters. The first chapter deals with the development and comparison of structural elements of the personal income tax and social security in both countries simultaneously during the period.
