It can be said that Science is the search for the truth. The universe is ultimately unknowable, however in Western Philosophy people believed that they could understand the universe. In modern theories the concept of time is limitless, unlike Buddhist views who thought that time was simply limited.
Emanuel Kant was a philosopher who believed that we can not know the truth. Not only this but he also thought that you always have to have an honest opinion of something. This can relate to Kant’s concepts of A Priori and Posteriori.
A Priori is before experience, where you can understand something before you experience it. Such as if you were told about a triangle, you could systematically work out that it had 3 sides. A Priori ideas are based upon reason alone. On the other hand, Posteriori must be grounded upon experience and such ideas are constantly limited.

Before Kant, it was believed that the earth was a mix of objects which can relate to the mirror theory of mind and reality. The empiricists such as Bacon and Newton thought that the cosmos is the sum total of many things. These can be a variation of different sizes and are difficult to see, but they are ‘there’ as objects whether we can physically see them or not. This theory can be related to Copernicus who was a Polish ecclesiastic. Copernicus lived in the 16th Century, yet his theories and beliefs lasted much longer. He believed early that the sun is at the entre of the universe. This was named the heliocentric model. He stated that the earth has a two fold motion; a diurnal rotation and an annual revolution about the sun. This theory was only put through as a hypothesis. A Similar Philosopher, Kepler, who was born 100 years after Copernicus is an example of what can be achieved by patience. He was the first important astronomer after Copernicus to adopt the heliocentric theory. Kepler’s first idea was that planets move in ellipses. A general belief of all astronomers where that all celestial motions are circular. To explain planetary motions, epicycles were used. This is the curve traced by a point on a circle which rolls on another circle. The circle was a perfect figure and the celestial orbs were perfect bodies, both Plato and Aristotle closely related to gods. Ultimately this invented the idea that a perfect body must move in a perfect figure, since the heavenly bodies move freely, their motion must be natural.

Both Newton and Einstein came from the Copernican revolution. It asks questions such as; Does the earth really orbit the sun? Where is the centre of the universe? If Newtons laws of motions describe motion from one point to another, can there be any motion if there are infinite distances?
In Newtonion science, it can be said that there are actually no limits and you can basically find out anything scientifically. This worked for the steam age which relates to the way Newtonian physics benefitted the making of steam trains. Francis Bacon, rejected the copernican theory, believing that philosophy should be kept separate from theology. Bacon believed that the only evidence of a God was humanities reason.

The Verification principle is an understanding of what is the truth. The truth of any proposition is the way you verify it. If a proposition cannot be verified it is neither true nor false. Ultimately, non verifiable principles have to be separated by verifiable principles.

Kant’s view of the cosmos is much like a computer game where the object, landscape, time and space are created in consciousness and then fades away again. For people who play computer games in their spare time, often find themselves immersed in the world the game creates, then once they stop playing the game, the world disappears. This is a simple way of understanding Kant’s view of the cosmos. However, Kant was not a pure idealist, both him, Schopenhauer and Nietzsche stated that existence is not a predicate of any possible object, nothing actually ‘causes’ existence.

Aristotle, much like Kant, was extremely interested in the truth and what can be classed as ‘actual truth’. Aristotle’s logic arises the argument of Deduction VS Induction. This is written within ‘The Organon” and describes to us how deduction preserves truth and expects authority above everything else. An example of deduction is that all swans are white. This is a swan therefore it is white. However this example is a flawed deductive argument as not all swans are white. Aristotle said 'all men are mortal' e.g. Socrates is a man therefore he is mortal. This is an example of deduction as you start with a general proposition/statement then you get the truth from it. 

Epistemology is the branch of Philosophy cornered with the nature of knowledge. The word comes from the Greek term meaning knowledge and understanding. 

John Stuart Mill who lived through the 1800's was a British Philosopher, political economist and civil servant. Mill describes the 'system of logic' as a textbook of the doctrine that derives all knowledge from experience. He went beyond his predeccors in claiming that not only science but also mathematics can be derived from experience. Mill's theory of the inductive truth relates to generalisations being based on individual experiences. Assertions of these truths, must always be hypothetical. Consequently, the principle is never accurately true, for one measured mile's length is not always equal to another. Ultimately you would always detect some difference. 

Considered as a Philosopher, John Henry Newman belonged to the same empiricist tradition as Stuart Mill. Newman believed that the only direct acquaintance we have with things outside ourselves, comes through our senses. We have to be near things to touch them, we can neither see nor hear not touch things past or future. Newman asserted that reason does not perceive anything. The exercise of reason is to assert one thing on the grounds of some other thing. Newman identifies two separate operations that are exercised when we reason. 

1. Inference
2. Assent
Both operations are quite distant from each other. We often assent to a proposition when we have forgotten the reason. It has been said that assent may be given without adequate evidence or argument and this often leads to error. Locke maintained that this is always wrong. He stated "Whoever goes beyond this measure of assent, it is plain received not truth in the love of it, loves not truth for truths-sake, but for some other by-end."(From the essay concerning Human Understanding) Locke maintained that there can be no demonstrable truth in concrete matters therefore assent to a proposition must be conditional. Newman however disagreed. He believes there are no such things as degrees of assent, though there is room for opinion without the assent that is necessary for knowledge. 
Each of us are certain that we will one day die but we can not give evidence on this. 
Simple assent - is done unconsciously. 
Complex assent - must provide some type of proof

C.S Peirce was an American Philosopher. He was educated as a Chemist and employed as a Scientist for 30 years. In today's age he is largely appreciated for his contributions to logic, philosophy, science and for his founding in pragmatism. Peirce devised an epistemology appropriate to an age of scientific inquiry. He presented this in a series of articles in the Popular Science Monthly entitled 'Illustrations of the Logic of Science'. One of the most famous written articles was 'The Fixation of Belief' where Peirce observes that inquiry always originates in doubt and ends in belief. Peirce believes that in order to settle our beliefs, four different methods are commonly used.
The first - method of tenacity
The second - the method of authority
The third -  the a priori method
And finally the scientific method
Ultimately, Peirce thinks that we may take a proposition and repeat it to ourselves, dwelling constantly on the good and bad points of the proposition. In all he believes that we must adopt the fourth method, the scientific method as it portrays the existence of a reality independent of our minds.

Frege was a German Mathematician and Philosopher and is considered to be one of the founders of modern logic. He was ultimately not interested in epistemology for his own sake, but strived to set out the relationship between epistemology and other related disciplines. In the tradition started by Descartes, he thought that epistemology had been given a large role in Philosophy when it should of been assigned to logic. A proposition may be thought of without actually being true, yet it may be true without being thought of. We are not owners of our own thoughts, these thoughts are grasped and anyone can do this.

Six years before Frege published his articles on the nature of thought, Bertrand Russell had written his brief problems of philosophy, a book that was to give many generations of philosophy students their own introduction into epistemology. Russell was actually a godson of John Stuart Mill and aimed to be faithful to the British empiricist tradition. Russell believes that things must be doubted. A table will look and feel different at different angles and to different people in different circumstances. The real table is not what we immediately experience therefore there is always a sense of doubt. Sense-data are the only things of which we can be really certain. Descartes brought his own doubt to an end with 'I think, therefore I am'. However Russell states that sense-data brings no assurance of an abiding self and what is really certain is not 'I am seeing a brown colour' but a 'brown colour is being seen. Ultimately sense-data are private a personal. Russell goes on to state that there is no proof that the whole of life is not just a dream.

Wittgenstein, an Austrian-British Philosopher created a private language argument, which showed that there are no ways of identifying items of consciousness without a reference to the public world. He believed that doubt needs grounds and a genuine doubt must make a difference in someones behaviour. For example, someone is not really doubting whether they have a pair of hands if they use their hands as we all do.

HCJ - Lecture 1

Science is the search for the truth.
Human condition - we can not know the truth - Kant
The universe is ultimately unknowable. Kant, apart form believing that we cannot know the truth, also thought that you always have an honest opinion about something. This can relate to us as Journalists because our job is to have an opinion about almost everything.
Before Kant, it was believed that the earth was a mix of objects which can relate to the mirror theory of mind and reality. Even Plato believe the forms existed independently of human consciousness. The empiricists however such as Bacon and Newton thought that the cosmos is the sum total of many things. Some of these are large, some small/remote and difficult to see but they are 'there' as objects whether we can physically see them or not.

A Priori - is before experience. An example of this is if you were told about a triangle, you could work out that it had 3 sides, therefore enabling you to understand what it was before experience. These are based upon reason alone.
Posteriori - must be grounded upon experience and are constantly limited.

Kants view of this is that the cosmos is much like a computer game where the object and the landscape, space and time are created in consciousness and then fade away again. For those avid gamers, for the time you are playing the game you can see everything there and you are immersed in the world, however once you finish the game that world has faded away. This is an easier way of understanding Kant's idea of the cosmos. However, Kant was not a pure idealist, and did not believe that things are really there but in a noumenal form.
From Kant, Schopenhauer and Nietzsche, we inherit the idea that existence is not a predicate of any possible object, nothing actually 'causes' existence.

If no one is perceiving the object, does it exist? - Barclay

Electronics and the explosion of innovation in technology, from medicine to space travel are based on the firm idea that we know virtually nothing but that humanity has a capability to strive to know more. As a society we are constantly wanting to more of something and ultimately what we have just is not enough. This can also relate to Journalists and the way that they, in their personalities, strive to learn more and know more about a particular person or topic. As Journalists we go by the idea of 'playing dumb', that we 'know nothing'. We attribute statements to the source, and never say we know the truth.  This idea is similar to Nietzsche.

Logic - invented by Aristotle, bases upon the ideas of deduction and induction.
Deduction preserves truth and respects authority above all else. It moves from a general proposition to a particular one.
Induction is the opposite, it moves from a particular proposition to a general one.
Aristotle said 'all men are mortal' e.g. Socrates is a man therefore he is mortal. The idea of this is you start with a general point then you get the truth from it.

Newton to Einstein - The copernican revolution
- Does the earth orbit the sun?
- Where is up, where is down?
- Where is the centre of the universe?
If Newtons laws of motions describe motion from one point to another, can there be any motion if there are infinite distances?
In Newtons science, in some ways there are no limits, ultimately you can find out anything scientifically.
The steam age was when the Newtonian physics highly benefitted stream trains. However, Newtons ideas do not relate to electronic devices. For 200 years, Newtons laws were regarded as true.

We see the universe in 3D because we are 3D beings - Russell on Kant

Perception is ultimately subjective, e.g. what we call blue is different at different times of day or the lighting conditions of the room change.

Zeno's paradox - These are a set of philosophical problems which were said to be made by Zeno who was a greek philosopher. They supported Parmenides's doctrine that 'all is one'. Both philosophers believed that motion is nothing but an illusion. Based on Plato's Parmenides, Zeno took on this particular project of created the paradoxes because other philosophers had created ones against Parmenides.
- I understood this as a matrix type of thing where the characters can do stuff which is unexplainable.
- This was created 3,000 years ago.
- Zeno said that Achilles fires an arrow and the arrow goes through specific points. If the universe is large and you can divide spaces, then motion is impossible.
- Zeno believed that if motion exists then time cannot.

Verification principle
The truth of any proposition is the way in which you verify it. If a proposition cannot be verified, it is neither true nor false. E.g. 'It's raining'. If it can not be verified then it can not be proved to be true or not. Non verifiable principles have to be separated by verifiable principles.
