Of somebody eloquent, people will say “He as a gift with words”. Eloquent is a term associated with statesmen like US President Obama in our time, or with preachers like Bossuet in Pascal’s time. But could a scientist be eloquent? Blaise Pascal, the well-known scientist of old, defines eloquence in terms that make it relevant to scientists.
“Eloquence is the art of saying things in such as way that 1) those to whom we speak listen without pain and with pleasure; 2) their own interest encourages them to reflect upon what they hear.
It establishes a link between the heart and mind of the listener on the one hand, and between our thoughts and how we express them on the other hand; This assumes that one has studied the heart of man and knows its power so as to control how much and what to say. One must become one with the listener and test our heart on the very words we will use to see whether they fit and rally the listener to our views. We must, as much as possible, keep ourselves to what is simple and natural, refrain from making much out of nothing or nothing out of much. Being a thing of beauty matters little if it does not serve the listener; In beauty is nothing to trim or add.”
Pascal Thought 16.
What I observe in Pascal is his conviction that eloquence is not a gift, but a science and the fruit of labour to reach conciseness. It is based on our thorough observation and study of others enabling us to reconstruct them in ourselves in order to test the convincing power of our own words.The power of words, however, cannot be built on exaggeration. Self-control is necessary to avoid the distorted and the complex at the expense of the natural and the simple. Words gain power when their number is restricted.
Pascal describes eloquence as a tool that leads to reflection. Unless your audience reflects and thinks about what you have just said, you will not convince. A man of many words leaving no room for silence is not eloquent. Silence punctuates speech. The audience uses silence as a time to think. Silence keeps your sentences simple and natural. Paradoxically, with silence, your speech is more concise. Framed by two moments of silence, in your sentence “is nothing to trim or add” (see also Saint Exupery ).
There is no threat, no perceived accusation in eloquent speech. There is pleasure. Words that judge like limitation, failure, disadvantage are replaced with words that encourage like enhancement, extension, consolidation, strengthening, building blocks. Eloquence belongs in a scientific presentation. It befalls the scientist to reveal how beautiful a contribution he or she has to offer without putting others down.
Although Pascal referred to the eloquence of words, Saint Exupery broadens the landscape to include figures–the scientist’s best tool to convince. Figures are our most eloquent allies. How eloquent are your visuals? Is there nothing in them to trim or add? Have you looked at them with the eyes of your audience? Have you designed them to support a point that requires convincing? Are your visuals “things of beauty” or is complexity, judgment, or glut disfiguring them? Do your figures make people think?
