Italy
Ancient
Key Works & Ideas:
He said that reality was simple and unchanging
Famous for his paradoxes, many of which were discussed for centuries after his death
The arrow – if time is a series of points on a line and an arrow travels along that line, what can be said about its movement in an instant? It can’t move in an instant as an instant has no duration, therefore it must be at rest…so is it moving at all?
Achilles and the tortoise – Achilles gives the tortoise a 10 m start, by the time he reaches the 10 m, the tortoise will have moved on a little, by the time he reaches the second spot, the tortoise will have moved on, and so on infinitum. So Achilles can never catch the tortoise.
Life History

Debates never really concluded and Socrates views not clear.
He featured in Plato’s dialogues which are used as a key source of his ideas. 3 striking examples are Apology (Socrates response to his charge), Crito (Socrates ethical views discussed with his friend Crito)and Phaedo (an emotional account of his final hours)
One of his viewpoints that no-one does wrong voluntarily or deliberately became known as The Socratic Paradox.

Greece
Ancient
Key Works & Ideas:
Epistemology: We cannot have genuine knowledge of the temporary and changing world of our everyday lives e.g. When does green cease to be green (when in the dark, when faded? What makes a dog a dog? Is a bald dog that loses a leg and a tail still a dog?). We can have true beliefs which are useful to use. Genuiune knowledge is recollected from a previous incarnation which a teacher helps us remember. Said we forget knowledge during the trauma of birth.
Metaphysics: Theory of Ideal Forms – said there are unchanging, ideal entities of which other things are merely shadowy copies. I.e. there is an ideal colour green and an ideal dog
Politics: Republic - his greatest work. Main theme is that the ideal state is ruled over by a philosopher king as he would be most able to achieve true knowledge and wisdom. Did not believe in democracy, instead argued for an “aristocracy of merit,” that could be ruled by the best and the wisest people.
Thought that most ideas were innate
Platonic relationships are ones that are based on intellectual exchanges.
Meno deals with virtue and knowledge.
Used metaphor such as in Myth of the Cave.
Life History
Very little know about his life but his works remarkably well preserved.
‘Plato’ a nickname meaning ‘the broad one’ a reference to his shoulders!

?father died when he was young
Left Greece for over 10 yrs when Socrates was executed.
When he returned he started a school called the Academy that stayed open for over 900 years. Closed by Roman Emperor Justinian for being pagan.
Some reports say Academy could have been his house where he took pupils (rather than a Uni.)
Summary: Recognised as the father of Western Philosophy by some, his well preserved writing remain amongst the most interesting, rich, subtle, broad and beautiful in philosophy and will probably still be read in another 2,000 yrs.

England
Medieval

Ockham’s Razor is the idea that the simplest explanation for something is probably the most likely.
Promoted Nominalism, which denies the existence of universals. This means he believed that only individual things existed and that any groups they were put in was an abstract concept. For example, bananas and apples existed, but not fruit. ‘Fruit’ does not exist because ‘fruit’ is simply a name and has no real meaning.
Life History
Became a Franciscan monk before going to study at Oxford and Paris but failed to gain his qualifications to teach due to begin outspoken about the church.

It is not wisdom but Authority that makes a law.
England
Early Modern
Key Works & Ideas:
His masterwork Leviathn has a very pessimistic view of human nature which he called the state of nature
In the State of Nature nothing curbs a persons absolute freedom – everyone has absolute liberty, therefore conflicts and crime are inevitable due to no desire to cooperate. People fear each other and there is no order, only chaos. It is not a state that once existed, but a constant state one needs to move away from
The Social Contract Theory of the State describes a situation where people give up absolute freedom of the State of Nature to be content with as much liberty as they would allow others to have towards them. Therefore those that want to avoid a State of Nature sign up for a social contract which transfers absolute freedom from the individual to a group that aims for security for all.
Was also interested in language and said that many problems of communication arose from the mis-use of language.

Thought that much knowledge (such as that of God) was innate
Published The World which was a scientific treatise on astronomy, geometry, mathematics, optics, meteorology
Four rules for rational enquiry; 1) accept nothing as true unless it is so clearly and distinctly presented there is no reason to doubt it, 2) break problems down into as many smaller problems as possible, 3) begin with what is most simply and easily understood and build on this to larger issues, 4) review entire chain of thinking so ensure nothing is omitted.

Ethica describes a reality that is conceived and controlled by one entity whether it be God or Nature that determines what happens so there is no free will. His belief in determinism was absolute as he says we are not aware we do not have free will even though we might be aware of what we are doing.
Built his theories in his work on Ethics by examining definitions.
Said we should strive to see reality from the perspective of eternity – this can be helpful when suffering i.e. to see our place in the whole and beyond our own misery.
There is no absolute good or bad. Behaviour is relative to the endeavors & conceptions of various individuals. If viewed from God’s perspective there is no evil in sin due to there being a total perspective which the individual does not have.
Believed human’s task was to see thing from the point of view of eternity so that we see our small place in a larger world and therefore free ourselves from our personal passions.

By the end of his life was back in the British courts writing on a broard range of topics from education, philosophy, politics, and religion.
Key Works & Ideas:
In his Essay Concerning Human Understanding he spoke against innate understanding saying that we are all blank slates (tabula rasa) which are then written on by experience. Said there was no evidence of innate ideas.
His idea of primary and secondary properties of objects states that the primary properties cannot be separated from the object, such as its state, figure, bulk, motion. Secondary properties are the ones that produce sensations such as taste, sound, smell, touch. i.e. the shape of a lemon tells us about the world, but not its taste.
States that ideas are simple and complex. Simple ideas cannot be broken down into other ideas and are a single conception in the mind. Complex ideas are composed of the shifting and sorting of simple ideas.
Criticism
Evolutionary psychology & sociobiology show that some behaviours/knowledge is innate (particularly those related to survival)

His Principles of Human Knowledge presented many of his argument.
Distinguished between minds and ideas.
Said that all objects of human knowledge are ideas through immediate experience such as; taste of food, cool of ice, visual stimulus of trees out the window, or ideas we have of our emotional states through imagination and memory, such as the taste of a lemon can exist only by remembering it.
Life History
Born in Kilkenny and educated in Trinity College Dublin.
Was later welcomed into intellectual life in London.

Key Works & Ideas:
Rejects the idea of personal identity and believes that we change over time. Has no evidence that any part of our self endures in order to define who we are, even though we may have perceptions of enduring identity.
Didn’t believe in causal relationships, just because something happens 100 times doesn’t mean we should expect it to happen 101 times.
Many of his writings need to understand 3 distinctions; 1) impressions (something that happens in real time during an experience) and ideas, (copies of impressions in memory of them), 2) Simple ideas (can’t be broken down and formed from impressions) and complex ideas (made up of simple ideas and don’t necessarily need impressions ,3) Facts and Ideas. Ideas can come into being by thinking alone whereas facts need a truth from the world. From all this he concluded that reason has no hand in our beliefs of our self, the external world or inductive inference.
On causality - because we have only limited sense experience we need to employ causal thinking. When we read about things we can say the ‘report’ is caused by the thing we are reading about.
Criticism
People found him difficult to understand h. Mostly other philosophers read him during his life. Was read more after his death.

His most important work The Social Contract discusses how humans used to live peaceful solitary lives meeting their basic needs. When man decided to claim a piece of land as his own and enclose it, civilisation began. From this man had to justify and maintain his property which led to inequalities and moral depravity.
Once people start to live in social groups their individual needs and freedoms are blocked unless they represent themselves as part of the groups Sovereign Body.
His Discourse on the Science and Arts questioned whether their advancements had improved morals as the idea was that once we were comfortable through technology and the arts, we became decadent.
Criticism
People in a sovereign body do not necessarily put aside their personal interests for the common good as common good is not always their political interests i.e. Hitler/tyranny of the majority.
Was accused of being anti-enlightenment due to ideas in his Science and Arts discourse. (enlightenment says the best hope for humankind is the progress through science and arts out of superstition and myth.

Key Works & Ideas:
Advocates that truth is what works. People have socially sanctioned habit that allow them to live their lives. When habits break down (or new scientific data does not fit with scientific thinking) we have genuine doubt and have to reconcile the situation. We do this by isolating the significant problem, provide a number of hypotheses and then systematically test them. New beliefs must then be incorporated into the existing framework. All this requires sophisticated and flexible thought.

Key Works & Ideas:
The Russell Paradox asks if the set of all sets which doesn’t include themselves as members, include itself as a member? E.g. Mayors can live in the towns they work in (set 1), or not (set 2). If the Mayors that don’t live in the town they work in live together in a town, where should their Mayor live?

Summary:
Capitalism definition The mind terrorism Capitalism as near to Total Paradigm Shift
Asking for an economic definition of capitalism is like inviting a liar to get in the mood for lying. Capitalist = Economic. Even western people who disgust capitalism largely behave capitalist
Slightly changed a famous remark of the existentialist Sartre characterises the following article: Man is not the sum of what he sees, but the totality of what he does not yet see, of what he might see. 
The relativism in this remark is taken by me as trigger to show that capitalism is a perfect example of what was meant Kuhn as inventor of the words paradigm shift, because this Western Word view totally changed the also Western (Roman Catholic Christian) intelligence. The idea 'Capitalism' ventilated by the European Karl Marx prefers individualism above collectivism (using the dubious law of the fittest). Though the French thinker Louis Althusser (teacher of Michel Foucault) claimed that Marx was fundamentally misunderstood. Althusser was sure Karl Marx had constructed a revolutionary view of social change (a 'paradigm shift' or 'epistemological break'). Althusser believed that Marx's rejected the rational dualism subject-object, or body-spirit. That makes Marx's work ununderstandable for 'rational' scientists. Anyway the writings of Karl Marx have essentially different interpretations depending on the locally dominant paradigm (say Buddhism, Christianity or Islam). And all over the world it became a myth. Mind that the concept 'rationalism' originated in pre industrial France, and that the concept 'capitalism' comes from industrial England (the temporary home of the Austrian Marx). WHAT IF you're a native rural Chinese who meets this Western born fantasy, totally indoctrinated by 'rational' Maoism and still grounded in common sense Buddhism. The fact that Industrialism dominated and shaped present Europe, does in no way mean that this product of Roman Catholic ethics should be used worldwide. In most armies the common sense idea 'respect' is still valued, only not made into a real body-mind DECISIONS (intuition) like: "STOP, the killing must be over!" In power thinking Western armies are ABUSED by politicians for aiming at dominance of Capitalism. Politics should make ethics, not promote power thinking. Catholic Culture (however good meaning) didn't get succesful by peacefully integrating with others, but by dirty colonial wars inspirated by the egoism in industrialism.
Steps
I'll use the following steps: 1. Getting started 2. Continuous growth and Jumps 3. Evolutionary Forces need cultural earthquakes to go from Stationary into Oscillating 4. Half Frankenstein, half Mona Lisa 4. Kuhn and Marcuse both made subcultures rumble 5. Evolution can be seen as an endless sequence of oscillations ending in jumps 6. Captains of Evolution 7. The miscourse Rationalism: Western Truth shrank temporarily 8. You get the Leaders that you deserve 9. Karl Marx steered from plain Rationalism to Economic Rationalism 10. Flash of an Eye 11. Nobel Prize winning arrogant Inner Sea Captain versus modest Ocean Captain
