[Sir Francis Dashwood]

You are free to define words as you will. And using your definitions of choice, you can emit an unlimited number of statements that are true by definition.

The axiomatic truth of procreant mammalian biology requires no words.

We are defined by nature. Civilization only gives the weakest man the ability to kill the strongest.

The axiomatic truth of procreant mammalian biology requires no words.

Reality is not an axiom-based system of formal logic, so I don't see how your statement can be mapped to any particular meaning, nor how it might be sequitur to the discussion.

We are defined by nature. Civilization only gives the weakest man the ability to kill the strongest.

The ability of the stronger man to kill the weaker (or less often, the weaker man to kill the stronger) is neither a necessary nor a sufficient condition for the existence of a civilization. And a civilization is neither a necessary nor a sufficient condition for men to kill other men, regardless of their relative strength.
