how do you get such a curve?

well

You want to analyse a market at perfect competition conditions?

As I stated,

you start with an individual demand curve and try to aggregate the demand curves into a market one

but to do this

I know what you're talking about

you need presuppositions about reality

I am just unfamiliar with the English terminology.

now, the presuppositions about reality used *are false*

so we are using *non-evidential argumentation to construct a theoretical entity*

this isnt what the scientific method does.

You just said that they are based on empirical data...

demand is analysed, and then bundled into a curve for the entire market.

no

the law of demand is a presupposition

The law of demand?

That the higher the price, the lower the demand?

How is that a presupposition?

That is observable fact.

thats what gives you the shape of the individual demand curve

yes i agree

its a presupposition backed by evidence

but the aggregation of these individual demand curves

So where is the problem?

*is done by a method which uses false assumptions*

so we're constructing a theory based on *empirical falsities*

*this is unscientific*

As I stated, I am unfamiliar with the English terminology.

Explain what you mean by _individual demand curves_

the demand curve of an individual human

Since the demand graph would involve a measure of quantity that is demanded,

would it not only variate between 0 and 1 if it is an individual curve?

its not a probability?

...unless the individual wants several units of the product in discussion, I suppose
I was assuming each individual would only hold demand for 1 unit

its a measure of quantity and price

so it doesnt have to be 0<x<1

I meant

haha wtf!

0 or 1,
