"humans appreciate the beauty of sameness and also breaking of that sameness". True? Why?

Answer 1

Time causes the need for breaking the sameness, to see newness.

Answer 2

True because the human ego functions for certainty of identity, the mental object to sense perception for recognition. This 'breaking sameness', if I take the meaning for that expression correctly, happens when equality of self and other threatens the superior-ism of self. This taken as a whole becomes of the human primary negativity, before the development for philosophical positivity, when anti-ego or the actuality of self doubt as its essence is identified positively as in rational and empirical activity.

IV. Second Attitude of Thought to Objectivity
ONE. EMPIRICISM
§ 37

Under these circumstances a double want began to be felt. Partly it was the need of a concrete subject-matter, as a counterpoise to the abstract theories of the understanding, which is unable to advance unaided from its generalities to specialization and determination. Partly, too, it was the demand for something fixed and secure, so as to exclude the possibility of proving anything and everything in the sphere, and according to the method of the finite formulae of thought. Such was the genesis of Empirical philosophy, which abandons the search for truth in thought itself, and goes to fetch it from Experience, the outward and the inward present.
