Brutus would of gone much further with Cassius’s advice.
Not too much later in the dialogue the idea that there is a law of nature beyond the will of the stronger, of the dominant class, or of public opinion comes under attack. Cicero assigns this Academic task to a character named Philus. It is for him and all present an unwelcome but necessary task of testing and thus making the best argument that can be made against the seeming assumption that there is a justice grounded in the nature of things. The second passage in the Documents () provides an indication of the kind of argument Philus makes, which emphasizes both the variation in laws from nation to nation and time to time, and that even well-known philosophers seem to differ from common practice in interpreting a standard of justice like giving every person their due. Philus represents a set of arguments heard yet today against the idea of a natural justice and natural law, namely, that variations in “just” civil laws and customs and differing opinions even among leading thinkers constitute an indication that there exists no natural, common understanding of the right and the just.

Those views on nature’s way and natural law are expressed and explicated in the texts of Cicero appearing in the . The passages excerpted there represent the most direct and noted statements of Cicero on the character and basis of natural law. They are drawn from his (54–51 B.C.), (51 B.C. ff.), and (44 B.C.). In the brief commentary that follows here, an effort is made to bring out a coherent statement of Cicero’s teaching by offering assistance in contextualizing and interpreting these texts. Proceeding chronologically, this essay moves from Cicero’s most assertive and seemingly cryptic statement about natural law, through his speculations on how that foundational law fits in a larger cosmological and divine order, to his observations on both how nature’s standard is grounded in the very inclinations and capacities of humans and the prudential challenges of applying that standard to concrete moral dilemmas and decisions.
