coexistent

The ideal of this XII-century statesman was a strong central monarchy, coexistent with a national assembly.

Considered in this aspect, the knighthood and the feudalism of Europe were synonymous and coexistent.

Therefore an unending aggregate of actual things cannot be regarded as a given whole and therefore also not as coexistent.

Let us leave the negation of the negation for a little and look at "the coexistent individual and social property."

It is a law of Nature that in all things there are certain constituent parts, coexistent with their substance.
