Washington was on the right track; However I have yet to see a reply that justifies the need for political parties.
Can anyone actually give me a good reason why we need them. An answer such as "We need them otherwise we will open the door to tyrants" etc is not sufficient. I want a good argument in favour of political parties. It seems that the only answers I am getting are based on the fear of not having them or simply we need them.
Anyone?
There is no such thing as the perfect political system. Therefore, a justification for system X will often be of the form "well it's better than system Y in areas Z".
For example, if we've established that we prefer a democracy, there are a number of forms in which the public can have its voice heard. All forms have disadvantages. Winner-takes-all elections of individuals (e.g. US presidency, parliaments where every area is represented by 1 person, etc) often result in voting for the lesser evil, a problem less present with the proportional representation in proper multi-party democracies.
Another problem is that being good at getting elected is not the same as being good at ruling the country. When you have to vote for a person, this effect is amplified (voting for the guy who you want to have a beer with, etc). When you vote for a party with a specific philosophy, the problem is still present, but not to the same extent.
A party can earn a reputation for being competent and responsible with power. Our VVD, CDA and PvdA may not be the flashiest parties, their leaders annoying, some of their ideas completely opposed to mine, but in their long histories they have consistently produced boring smart people who kept the country running somewhat smoothly. These boring smart people, with their compromises and necessary but unpopular policies, might not have stood a chance if they had to be elected individually.
