6. Go through the paragraph given below and analyse it to show how the three basic principles of paragraph writing have been utilized-  There is a further difference. Though both attempt to discern and express order and unity in the variety of experience, their generalizing powers tend indifferent directions.

Science attempts to subdue a multitude of incidents to a grand generalization which, until challenged by new events, is universal in its application. Scientific generalization is capable of accurate prediction with reference to all future events that belong to the category of incidents with which it deals.

Humanistic works, on the contrary, are concerned rather with the individual experience, and they relate it to general principles not in order to have it lose its identity within them but in order to reveal its special meaning.

Humanistic works therefore tend toward uniqueness, and in their totality call attention to the diversity and plenitude of human experience. All sunsets can mean only one thing in any given statement about them in the science of physics.

But to a painter each sunset is a distinct phenomenon to be given a special personal meaning in the whole range of sunsets and is capable of many emotional evocations (10)
