The art of eloquence

Eloquence card: a hand holds a long sword.

  • Distinguish facts, interpretations and assumptions in a business request.
  • Ask open questions and seek the details that deepen mutual understanding.

  • State a clear proposition, distinguish claims, arguments and evidence, and specify the decision you seek.
  • Prioritize arguments in light of your audience’s concerns and values.
  • Choose examples and analogies that illuminate your message without distorting its meaning.

By the end of the workshop, you will be able to

  • Distinguish stated positions from underlying interests and prepare your best alternative to a negotiated agreement.
  • Explore options, use explicit criteria and assess concessions.
  • Clarify commitments and what implementation requires, then assess whether to reach an agreement.

In practiceNegotiate with asymmetric information, then review your preparation, the interests uncovered, possible trades and the strength of the resulting agreement.

Handle objections and difficult conversations: examine arguments, clarify misunderstandings and defend or revise your position with sound judgment.

By the end of the workshop, you will be able to

  • Distinguish substantive objections, misunderstandings and personal attacks.
  • Recognize false dilemmas and shifts in meaning, then restate the objection accurately.

By the end of the workshop, you will be able to

  • Build a clear thread connecting context, challenges, choices and future direction.
  • Show what is at stake through stories grounded in facts, relevant imagery and examples.

By the end of the workshop, you will be able to

  • Recognize when apparently shared terms carry different meanings.

  • Distinguish the roles of status, expertise, example and trust in your authority.
  • Hear a challenge and acknowledge an error without avoiding responsibility.

A small group taking part in a workshop around a table.

Your program.
Tailored to you.

The Signature Program brings together all fifteen workshops.

You can also compose your own, choosing those that speak to your priorities.

Together, we shape its guiding thread, pace and practical exercises.

Each reflects a French tradition of craftsmanship: precision in language, discernment and attention to detail.

From thought
to action.

Philosophy is the starting point of Philippe Gruca’s work: questioning assumptions, clarifying language and informing decisions. At atelier français, this discipline takes shape through three arts: rhetoric, communication and ethics.

Through his collaboration with Rational Games, he teaches negotiation through games and simulations. In-depth debriefs connect rigorous thinking with each participant’s decisions, relationships and responsibilities. Every year, he serves as an expert and judge at the Warsaw Negotiation Round.

He has taught at IÉSEG, Sigmund Freud University in Paris, the Institut français in Berlin, TU Berlin and SGH Warsaw School of Economics. He is also editor-in-chief of Inter-Nord. With French and Polish roots, he works in four languages: French, English, German and Polish.
