The Future of Human Nature

The heart of Habermas's argument is a distinction that sounds almost too simple: there is a difference between something that grows and something that is made. A person who grows up is shaped by countless influences — parents, teachers, accidents, their own choices — but no single author stands behind the shape they take. A made thing, by contrast, carries the intention of its maker. It exists because someone decided it should, and decided what it should be.

Until now, Habermas says, every human being has belonged firmly on the side of the grown. Your genetic endowment was nobody's decision. Your parents raised you, pressured you, loved you badly or well, but they did not design you from the ground up. Even the most controlling upbringing leaves open the possibility of revolt, reinterpretation, starting over — you can revise the story your parents told about you. The genome was the one thing that stood outside this whole negotiable field of influence, a contingency shared by everyone equally.

What does that asymmetry do to the person who results? This is where Habermas presses hardest. Our sense of ourselves as free agents, he argues, rests partly on a kind of fiction we never examine — the assumption that we are the undivided authors of our own lives, that nothing in us was dictated by a foreign will. We know, of course, that genes and upbringing shaped us. But those causes were anonymous. No one meant them. A designed person would know something different: that a specific other person, with specific purposes, authored a part of who they are, and did so before they could object.

Habermas calls this a disturbance in the symmetry between persons. Ordinarily, when adults stand before each other, they meet as equals — nobody is the acknowledged source of anyone else's being. Parent and child eventually arrive at that equality; the child grows up and the authority relationship dissolves into mutual recognition. But between a designed person and their designer, that equality can never fully arrive. The programmer remains, in a literal sense, behind the other's existence, and the designed person remains downstream of a decision they had no part in. The relationship cannot be reversed or outgrown.

Step back, and the deeper move in Habermas's book becomes visible. He is arguing that liberal neutrality, which he spent a lifetime defending, cannot be total. There is at least one background condition the liberal order quietly depends on and must therefore protect: the shared sense that all persons are, in their natural origins, equal and self-authoring. Strip that away and the moral architecture of equality loses its footing. We grant each other recognition as free and equal partly because none of us was made to another's specification. Begin making people, and the premise erodes — not for the individual alone, but for how the whole species understands what a person is.

This is why he frames it as an ethics of the species rather than a question of individual rights. Rights-talk assumes stable persons who can claim them. What is at stake with genetic programming is prior to that: the very self-understanding that lets us see ourselves as rights-bearers in the first place. Habermas is reaching for something he admits philosophy has rarely needed to articulate — a defense of the human as a form of life whose members meet as equals because they are all, in the same way, grown rather than engineered.

The book ends where it began, with a thinker reluctantly abandoning his own neutrality. Habermas had spent decades insisting that modern societies should not legislate the good life. Here he argues that one apparent extension of private freedom — parents authoring their children's traits — would corrode the shared condition that makes freedom and equality intelligible at all. The grown and the made are not just two categories of thing; they mark the difference between a person who can regard their life as their own and one who must reckon with another's design behind it.
