One of the most widely-discussed arguments against physcialism appeals to the conceivability of zombies, being which are physically or functionally identical to humans but which have no conscious experiences.

In sports, flow can be enhanced by mindfulness training, which has been associated with frontal theta activity (4-8 Hz).

It must be stated that there are not sufficient sources to study the theory and the practice of Zen Buddhism for the students and the teachers of Sri Lankan universities, who do their studies in Sinhala language. To fulfil this gap to some extent, this research is carried out. This tradition is named as “Dhyana” in Sanskrit, “Chan” in Chinese, “Son” in Korean, and “Zen” in Japanese. Though this...

In the theory of documentality, social objects are understood as inscribed acts; in extended mind theory, minds are considered to extend beyond the body to external processes and devices. Although for different reasons, these two theories rely on the semiotic dimension to reduce the differences between minds and documents. Yet, in a certain reading, such theories are implausible if we consider...
