A Quote by Karl Popper

A system is empirical or scientific only if it is capable of being tested by experience. These considerations suggest that not the verifiability but the falsifiability of a system is to be taken as a criterion of demarcation... It must be possible for an empirical or scientific system to be refuted by experience.
It must be possible for an empirical system to be refuted by experience.
A hypothesis is empirical or scientific only if it can be tested by experience. A hypothesis or theory which cannot be, at least in principle, falsified by empirical observations and experiments does not belong to the realm of science.
Now obviously the propositions of the system have reference to matters of empirical fact; if they did not, they could have no claim to be called scientific.
A theory is only as good as its assumptions. If the premises are false, the theory has no real scientific value. The only scientific criterion for judging the validity of a scientific theory is a confrontation with the data of experience.
What we can do is provide the tools, through our educational system, for people to be able to tell sense from nonsense. These tools include the scientific method, skeptical questioning, empirical evidence, verifying sources, etc.
In terms of their basic biochemical design....no living system can be thought of as being primitive or ancestral with respect to any other system, nor is there the slightest empirical hint of an evolutionary sequence among all the incredibly diverse cells on earth.
Our empirical criterion for a series of theories is that it should produce new facts. The idea of growth and the concept of empirical character are soldered into one.
The Saturn system is a rich planetary system. It offers mystery, scientific insight, and obviously splendour beyond compare, and the investigation of this system has enormous cosmic reach... just studying the rings alone, we stand to learn a lot about the discs of stars and gas that we call the spiral galaxies.
My experience and research has led me to the regrettable conclusion that our system of mass incarceration functions more like a caste system than a system of crime prevention or control.
A second possible approach to general systems theory is through the arrangement of theoretical systems and constructs in a hierarchy of complexity, roughly corresponding to the complexity of the "individuals" of the various empirical fields... leading towards a "system of systems." [...] I suggest below a possible arrangement of "levels" of theoretical discourse...(vi) [...] the "animal" level, characterized by increased mobility, teleological behavior and self-awareness...
The truth is that the phenomena of artistic production are still so obscure, so baffling, we are still so far from an accurate scientific and psychological knowledge of their genesis or meaning, that we are forced to accept them as empirical facts; and empirical and non-explanatory names are the names that suit them best.
The indispensability argument says (roughly) that if you have ample reason to accept an empirical scientific theory that makes indispensable use of mathematics, and that theory entails that numbers exist, then you have ample reason to accept that numbers exist. The argument affirms the antecedent of this conditional, and concludes that you have ample reason to believe that numbers exist. What is striking about this argument is that it seems to show that the empirical reasons that suffice for accepting a scientific theory also suffice for accepting a metaphysical claim.
The Soviet system is how everything here works. It's very difficult to break the system. The system is big and inflexible, uneffective, and also corrupt. And that is our main goal: to change the system, to break the system, to make it modern.
We have again a strange gap. We have the big scientific discoveries around the second, third century BC. Then we have an invention of the so-called Arab system, the positional system of counting with zero dated to the eighth or ninth century.
A system is a network of interdependent components that work together to try to accomplish the aim of the system. A system must have an aim. Without the aim, there is no system.
The system of fathers of the world church, the clergy system of the state church, and the pastoral system of the independent churches are all the same in nature. They are all Nicolaitans. In the Bible there are only brothers. There is the gift of a pastor, but no system of pastors. The pastoral system is man's tradition. If the children of God are not willing to return to the position of that in the beginning, no matter what they do, it will not be right.
