The problem comes when you return from render as: Wow, can't believe there is no compiler warning for this. Thanks, that extra newline formatting was the problem. Reviewed my code so many times. I suspect that this is a result of automatic semicolon insertion. It's probably parsing the first example as "return; Apr 20 at In this scenario, space is not "nothing" but, rather, a receptacle in which objects of matter can be placed. The true void as "nothing" is different from "space" and is removed from consideration.
This characterisation of space reached its pinnacle with Isaac Newton who asserted the existence of absolute space. For Descartes, there was matter, and there was extension of matter leaving no room for the existence of "nothing". The idea that space can actually be empty was generally still not accepted by philosophers who invoked arguments similar to the plenum reasoning.
Although Descartes views on this were challenged by Blaise Pascal , he declined to overturn the traditional belief, horror vacui , commonly stated as "nature abhors a vacuum". This remained so until Evangelista Torricelli invented the barometer in and showed that an empty space appeared if the mercury tube was turned upside down. This phenomenon being known as the Torricelli vacuum and the unit of vacuum pressure, the torr , being named after him.
Even Torricelli's teacher, the famous Galileo Galilei had previously been unable to adequately explain the sucking action of a pump. John the Scot, or Johannes Scotus Eriugena c.
His ideas mostly stem from, or are based on his work of translating pseudo-Dionysius. His beliefs are essentially pantheist and he classifies evil, amongst many other things, into not-being. This is done on the grounds that evil is the opposite of good, a quality of God, but God can have no opposite, since God is everything in the pantheist view of the world.
Similarly, the idea that God created the world out of "nothing" is to be interpreted as meaning that the "nothing" here is synonymous with God. Georg Wilhelm Friedrich Hegel — is the philosopher who brought the dialectical method to a new pinnacle of development. According to Hegel in Science of Logic , the dialectical methods consists of three steps.
First, a thesis is given, which can be any proposition in logic. Second, the antithesis of the thesis is formed and, finally, a synthesis incorporating both thesis and antithesis. Hegel believed that no proposition taken by itself can be completely true.
Only the whole can be true, and the dialectical synthesis was the means by which the whole could be examined in relation to a specific proposition. Truth consists of the whole process.
Separating out thesis, antithesis, or synthesis as a stand-alone statement results in something that is in some way or other untrue. The concept of "nothing" arises in Hegel right at the beginning of his Logic. The whole is called by Hegel the "Absolute" and is to be viewed as something spiritual. Sartre claims that this second kind of being is "nothing" since consciousness cannot be an object of consciousness and can possess no essence.
Equating nothingness with being leads to creation from nothing and hence God is no longer needed for there to be existence.
The understanding of 'nothing' varies widely between cultures, especially between Western and Eastern cultures and philosophical traditions. Achieving 'nothing' as a state of mind in this tradition allows one to be totally focused on a thought or activity at a level of intensity that they would not be able to achieve if they were consciously thinking. A classic example of this is an archer attempting to erase the mind and clear the thoughts to better focus on the shot.
Some authors have pointed to similarities between the Buddhist conception of nothingness and the ideas of Martin Heidegger and existentialists like Sartre, [20] [21] although this connection has not been explicitly made by the philosophers themselves. In some Eastern philosophies , the concept of "nothingness" is characterized by an egoless state of being in which one fully realizes one's own small part in the cosmos.
The Kyoto School handles the concept of nothingness as well. In computing , "nothing" can be a keyword in VB. Net used in place of something unassigned, a data abstraction. Although a computer's storage hardware always contains numbers, "nothing" symbolizes a number skipped by the system when the programmer desires. Many systems have similar capabilities but different keywords, such as " null " e. To instruct a computer processor to do nothing, a keyword such as " NOP " may be available.
This is a control abstraction ; a processor that executes NOP will behave identically to a processor that does not process this directive. From Wikipedia, the free encyclopedia. For other uses, see Nothing disambiguation. This section needs expansion. You can help by adding to it.
