Futurology in the context of "Holism in science"

The future is the time after the past and present. Its arrival is considered inevitable due to the existence of time and the laws of physics. Due to the apparent nature of reality and the unavoidability of the future, everything that currently exists and will exist can be categorized as either permanent, meaning that it will exist forever, or temporary, meaning that it will end. In the Occidental view, which uses a linear conception of time, the future is the portion of the projected timeline that is anticipated to occur. In special relativity, the future is considered absolute future, or the future light cone.

In the philosophy of time, presentism is the belief that only the present exists and the future and the past are unreal. Religions consider the future when they address issues such as karma, life after death, and eschatologies that study what the end of time and the end of the world will be. Religious figures such as prophets and diviners have claimed to see into the future.Future studies, or futurology, is the science, art, and practice of postulating possible futures. Modern practitioners stress the importance of alternative and plural futures, rather than one monolithic future, and the limitations of prediction and probability, versus the creation of possible and preferable futures. Predeterminism is the belief that the past, present, and future have been already decided.

Posthuman or post-human is a concept originating in the fields of science fiction, futurology, contemporary art, and philosophy that means a person or entity that exists in a state beyond being human. The concept aims at addressing a variety of questions, including ethics and justice, language and trans-species communication, social systems, and the intellectual aspirations of interdisciplinarity.

Posthumanism is not to be confused with transhumanism (the biotechnological enhancement of human beings) and narrow definitions of the posthuman as the hoped-for transcendence of materiality. The notion of the posthuman comes up both in posthumanism as well as transhumanism, but it has a special meaning in each tradition.

In futurology, especially in Europe, the term foresight has become widely used to describe activities such as:

• critical thinking concerning long-term developments,
• debate,
• wider participatory democracy, and
• shaping the future, especially by influencing public policy.

In the last decade, scenario methods, for example, have become widely used in some European countries in policy-making. The FORSOCIETY network brings together national Foresight teams from most European countries, and the European Foresight Monitoring Project is collating material on Foresight activities around the world. Foresight methods are used more and more in regional planning and decision–making (“regional foresight”). Several non-European think tanks, like Strategic Foresight Group, also engage in foresight studies.
