Meanings of purposive unity in English

By a free act of faith the scattered and imperfect fragments must be built into a purposive unity.

The solar system may be regarded as a unit, but it has not the purposive unity of a living body.

This purposive unity cannot well be secured without spatial contiguity; here, as in sculpture, a unified life demands a unified material.

The purposive unity must now transform itself into an endless complexity, and our own self becomes a composite of hundreds of thousands of elements.
