What is the human need for science and philosophy?

The human need to know the invariants from variants

Every human needs a sucess everywhere forever to exist. Every human, to be successfull, has to know everywhere forever. But, no human knows everywhere forever. The lack of knowledge and the need to be successfull demands every human to distinguish and know the invariants from variants. The invariants are expected to exist invariably everywhere forever. All that do not exist invariably everywhere forever are the variants.

The Unity of Design

The human need to distinguish and know the invariants from the variants reflects in the human inquiries, design of languages, and in the unity of design of "different" sciences and philosophies. The human ways and means to distinguish and know the invariants from variants are the different sciences and philosophies.

The Eternal Inseparability

An invariant is distinct from a variant. But, an invariant is inseparable from a variant. An invariant invariably exists in every state of a variant. Every human explores the ways and means to distinguish and separate these eternal inseparables.

The invariants are denoted by different names

The invariants are known by different names. A Characteristic is that invariably exists in every state of a variant. An ideal is that exist in every state of every variant. For examples, All that invariably exist in every state (small, medium or big) of a human are the characteristics of the variant, the human.

All that invariably exist in every state (small, medium or big) of a circle are the characteristics of the variant, the circle.

All that invariably exist in every state (small, medium or big) of a triangle are the characteristics of the variant, the triangle.

All that invariably exist in every state (small, medium or big) of height of trees are the characteristics of the variant, the height of the trees.
