What Is a Truism? | Definition & Examples
A truism is a statement that is so obviously and self-evidently true, that it seems pointless to mention it. Using a truism is often looked down on, but they can be useful when explaining something at a basic level.
Truism definition
By its very nature, a truism can seem wise or profound when first encountered: “Look before you leap” can seem like good advice; indeed, it is good advice. But very often it can be offered as a platitude rather than constructive advice on a specific course of action.
Sometimes, whether a statement is a truism or a vital truth can be a matter of opinion. “Two wrongs don’t make a right” might seem like a truism, but in the heat of the moment, it can be useful advice that helps to deescalate a fraught situation.
Why do writers use truisms?
Given that truisms are generally viewed negatively, it is worth considering why writers use them in their work.
Characterization. Authors use truisms to demonstrate that a character is perhaps idealistic, naive, or shallow.
Irony and humor. Truisms can be used by authors to create humor or irony.
“Maybe I should leave well enough alone
I might not be perfect but I’m me to the bone
I don’t need to change my style
Been this way for a long, long while
There ain’t nothing that I got to fix
And you can’t teach an old dog new tricks.”
As a rhetorical device. Writers and speakers sometimes use truisms as a rhetorical device, to help to imprint an idea in their audience’s minds.
“ … while we breathe, we hope, and where we are met with cynicism, and doubt, and those who tell us that we can’t, we will respond with that timeless creed that sums up the spirit of a people: Yes, we can.”—Barack Obama victory speech, November 2008.
Creating common ground. Given their self-evident nature, truisms can help to create a sense of common ground between people. Like rhetoric, it can be used by politicians to create a sense of unified purpose and belonging.
Simplifying complex ideas. Complex ideas are notoriously difficult to communicate effectively to an audience, especially in spoken form. A truism can cut through the complexity and give a sense of understanding.
Truism examples
Here are some of the more commonly encountered truisms.
Change is the only constant | Money doesn’t buy happiness |
If at first you don’t succeed, try again | Time is a great healer |
You win some, you lose some | It is what it is |
What will be will be | Knowledge is power |
Everyone makes mistakes | Patience is a virtue |
Happiness comes from within | Necessity is the mother of invention |
Terms related to truism
There are other terms that refer to truths that are generally accepted, but that have different connotations:
- Platitude. When a statement or advice becomes so overused that it loses its power or meaning, it can become a platitude. That doesn’t mean it is no longer true, but it loses its effect (e.g., “If at first you don’t succeed, try again”).
- Aphorism. Aphorisms are short statements, usually requiring some thought, that express a truth about life (e.g., Socrates’ statement “The unexamined life is not worth living”).
- Bromide. Sometimes common sayings, intended to be a source of comfort, become robbed of their effectiveness by overuse (e.g., “Time is a great healer”).
- Adage. An adage is a memorable expression, usually quite condensed, that is generally seen as a wise saying (e.g., “You can’t teach an old dog new tricks”).
In everyday English you can use truism, bromide, and platitude as synonyms.
