Franklin believes any constitution the Convention approves will be imperfect because it is written by imperfect human beings, each bringing their own biases, interests, and limitations.

Core Reason: Human Imperfection

Franklin argues that when you gather a group of people “to have the advantage of their joint wisdom,” you also inevitably gather their prejudices , passions, errors of opinion, local interests, and selfish views. Because of this mix of flaws and conflicts, he says it is unrealistic to expect a perfect document to come from such an assembly.

His View of the Constitution

Even with these faults, Franklin is actually impressed that the Constitution comes “so near to perfection” given the circumstances. He accepts it “with all its faults” because he thinks a general government is necessary, doubts that another convention could do better, and is not even sure that what he sees as errors really are errors.

Humility and Doubt of “Infallibility”

Franklin also believes individuals should “doubt a little of [their] own infallibility.” In other words, he thinks everyone—including himself—might be wrong about some of their objections, so insisting on personal perfection in the document would be both unrealistic and dangerous to agreement.

In Short

So, Franklin thinks any constitution from the Convention will be imperfect because:

  • It is written by fallible humans with conflicting interests and biases.
  • No group of such people can reasonably be expected to produce a perfect “production.”
  • Political realities and the need for unity mean a nearly good constitution, open to future improvement, is better than chasing an impossible ideal of perfection.

TL;DR: For Franklin, imperfection is inevitable in any human-made constitution—but that does not stop it from being good enough, or even the best realistically possible.
