An epiphenomenon is a secondary effect or byproduct that arises from a primary phenomenon but does not influence or alter the primary phenomenon itself. In other words, it is something that occurs as a result of something else but does not have any causal influence on the process that produced it. In philosophical terms, the concept is often discussed in relation to the mind-body problem and specifically in debates about consciousness.

Heterophenomenology is a term coined by philosopher Daniel Dennett to describe a method of studying consciousness and subjective experiences from a third-person perspective. It seeks to understand mental states and experiences by interpreting them from an external standpoint, relying on how individuals report their experiences rather than assuming direct access to those experiences. The key features of heterophenomenology include: 1. **Third-Person Perspective**: It approaches subjective experiences as data that can be observed and analyzed, rather than directly experiencing them.

The "intentional stance" is a philosophical concept introduced by the philosopher Daniel Dennett. It refers to an approach we adopt when trying to understand the behavior of others—be they humans, animals, or even artificial intelligences—by treating them as if they have beliefs, desires, and intentions. When we assume the intentional stance, we interpret actions and behaviors based on the premise that the entity in question has mental states that guide its actions.

Intentionality is a philosophical concept that refers to the capacity of the mind to direct itself toward something; that is, the quality of mental states that involves aboutness, or the ability to represent objects and states of affairs in the world.

In philosophy, the concept of meaning is multifaceted and encompasses various domains, including language, existence, values, and experience. Here are some key areas where "meaning" is explored: 1. **Semantic Meaning**: This area deals with the meaning of words, sentences, and symbols. Philosophers like Ludwig Wittgenstein and Gottlob Frege have examined how language conveys meaning, the nature of reference, and how context affects interpretation.

A "memeplex" is a term used to describe a collection or group of memes that are interconnected and work together to promote certain ideas, beliefs, or behaviors. The concept builds on the idea of a "meme," which, in this context, refers to cultural units of information that spread from person to person, much like genes in biological evolution.

The term "mental fact" generally refers to a statement or assertion that is related to mental states, processes, or phenomena. It can encompass various aspects of psychology, philosophy, and cognitive science. Mental facts might include truths about our thoughts, emotions, perceptions, and intentions. They are typically distinguished from physical facts, which pertain to the physical world and its properties.

Qualia (singular: quale) are often described as the subjective, individual experiences of perception and sensation. They refer to the internal and personal aspects of how we experience things, such as the redness of a ripe apple, the taste of chocolate, or the pain of a headache. Qualia are considered important in discussions of philosophy of mind, consciousness, and cognitive science, as they relate to the challenges of explaining how subjective experiences arise from physical processes in the brain.

The International Symposium on Fundamentals of Computation Theory (FCT) is a biennial academic conference that focuses on various aspects of theoretical computer science, particularly those related to computation theory. The symposium brings together researchers and academics from around the world to discuss recent developments, share their findings, and foster collaboration in areas such as algorithms, complexity theory, formal languages, automata theory, and related topics.
