A SHARED EDUCATIONAL AND ETHICAL BOOK PROJECT

From a communication concept to an age-appropriate story

“The Art of Fair Self-Assertion” develops the ethical and communicative foundations of clear, respectful, and responsible self-assertion. “Leni and Oscar and the Mystery of the Quiet Voice” translates these ideas into an age-appropriate story about courage, fairness, clear words, mistakes, and development.

The nonfiction book does not treat self-assertion as the mere enforcement of personal interests. It connects personal needs, rights, and boundaries with respect for the dignity and autonomy of others.

The children's book presents this tension through Leni and Oscar: Leni notices a great deal but initially remains silent for too long. Oscar is courageous but sometimes reacts faster and more loudly than the situation requires. Both learn a third path between withdrawal and attack.

The concept of fair self-assertion

Three levels of communication and three ethical pillars

Verbal level

Express observations, feelings, needs, wishes, and boundaries clearly and understandably in words.

Paraverbal level

Use tone, volume, speaking pace, and emphasis consciously and appropriately.

Nonverbal level

Use posture, gestures, facial expressions, and eye contact in ways that support the spoken message.

Respect

The dignity, boundaries, and autonomy of others are taken into account.

Responsibility

People take responsibility for their words, actions, intentions, and possible consequences.

Fairness

Personal interests are represented without disregarding the legitimate interests and rights of others.

Shared action logic

Notice → recognize feelings → name needs → state a boundary → speak calmly → listen → take responsibility

Four paths in conflict

Withdrawal, attack, manipulation, and clear self-assertion

The Whisperer

Withdrawal and silence

The Whisperer represents falling silent out of fear. Those who remain silent for too long may be unable to make important needs, observations, and boundaries visible.

The Shouter

Dominance and escalation

The Shouter tries to win through volume, pressure, or intimidation. This can intensify the conflict and push aside other perspectives.

The Twister

Manipulation and untruth

The Twister changes statements or contexts to gain an advantage. Any short-term effect comes at the expense of trust and clarity.

The clear voice

Speak truthfully and fairly

The clear voice connects awareness, courage, truth, respect, and responsibility. It protects one's own dignity without violating the dignity of others.

Thematic connection

Why the nonfiction book and the children's book belong together

Foundations

Explain the concept systematically

The nonfiction book explains what fair self-assertion means, why it matters, and how it differs from dominance, manipulation, avoidance, and selfish enforcement.

Communication

Connect words, voice, and body language

Fair self-assertion is not created by suitable words alone. Tone, volume, posture, gestures, facial expression, and eye contact also influence its effect.

Children's book

Make abstract principles tangible

Leni and Oscar experience concrete conflicts, mistakes, misunderstandings, and developmental steps. This makes fairness, clarity, and responsibility tangible through story.

Development

Not having to be perfect

The children's book shows that a clear voice does not have to be present at all times. It can be sought, practised, lost, and found again.

The two books

The Art of Fair Self-Assertion and the Mystery of the Quiet Voice

Each book can be read independently. Together they form an educational and communication project about clear communication, fair boundary-setting, courage, respect, and responsibility.

Shared competencies

What readers can develop across both books

Awareness

Recognize and distinguish observations, feelings, needs, and boundary violations more precisely.

Clear language

Express personal concerns clearly without threatening, demeaning, or deliberately distorting statements.

Voice and body language

Use volume, tone, posture, gestures, and eye contact in ways that support the message.

Setting boundaries

Say no, create distance, and seek help when a situation cannot be resolved safely alone.

Respect

Consider other perspectives without giving up one's own needs and rights.

Responsibility

Recognize personal mistakes, take their effects seriously, and adjust one's behaviour.

Conflict competence

Distinguish between withdrawal, attack, manipulation, and a respectful, clear response.

Courage and attention

Do not act too hastily, but do not remain silent indefinitely when something is unfair or harmful.

Different forms of assertion

Selfish enforcement and fair self-assertion

Unfair or one-sided enforcement

  • enforce personal interests without consideration
  • use pressure, threats, or humiliation
  • deliberately distort statements or facts
  • refuse to listen to other perspectives
  • reject responsibility for consequences

Fair self-assertion

  • state personal needs and boundaries clearly
  • speak calmly and as clearly as possible
  • consider the dignity and rights of others
  • listen and examine different perspectives
  • take responsibility for words and actions

A clear refusal is not automatically aggressive. Likewise, giving in is not automatically respectful. What matters are the situation, safety, intention, expression, power relations, and consequences for everyone involved.

Scope and limitations

What can be derived from the books — and what cannot

Covered in the books

  • fair self-assertion and clear communication
  • verbal, paraverbal, and nonverbal levels
  • respect, responsibility, and fairness
  • boundary-setting, listening, and I-statements
  • withdrawal, attack, and manipulation as problematic paths
  • age-appropriate reflection on courage and fairness

Not replaced or not fully established

  • medical or psychotherapeutic treatment
  • individual legal advice
  • professional protective measures in cases of violence
  • crisis intervention in immediate danger
  • complete empirical evidence of effectiveness
  • a universally suitable solution for every conflict

Self-assertion does not mean having to resolve every dangerous situation alone. In cases of violence, abuse, immediate danger, severe bullying, or major power imbalances, protection, distance, trusted adults, and appropriate professional support are more important than immediate direct confrontation.
