Caer por su propio peso

to be self-evident; **to be self-evident**; **to be obvious**; **to speak for itself**; **to be undeniable**; **to follow naturally**

Caer por su propio peso means to be self-evident, logically unavoidable or impossible to deny.

The expression emphasises that the facts speak for themselves.

• a conclusion is obvious
• an argument is overwhelmingly convincing
• the evidence leaves no room for doubt
• something is clearly inevitable
• no further explanation seems necessary

The metaphor comes directly from physics.

An unsupported object naturally falls because of gravity.

Spanish extended this image to ideas and arguments.

Just as gravity inevitably pulls an object downward, logic inevitably leads to a certain conclusion.

The expression highlights the natural force of the reasoning rather than physical movement.

The expression is frequently used in debates.

Speakers often use it to suggest that continuing the discussion is unnecessary because the evidence is already overwhelming.

For this reason, it can sometimes sound slightly emphatic or rhetorical.

Spanish uses caer in dozens of figurative expressions:

• Caer bien → to be liked.
• Caer mal → to be disliked.
• Caer en la cuenta → to realise something.
• Caer de pie → to land on one's feet.
• Estar al caer → to be about to happen.
• Caer por su propio peso → to be self-evident.

For such a common verb, caer has developed an extraordinary number of meanings that have little or nothing to do with physical falling.

Do not translate the expression literally.

Although English speakers understand the physical image, they would not normally say:

The conclusion falls under its own weight.

Instead, use expressions such as:

• It's self-evident.
• It speaks for itself.
• It's obvious.
• The conclusion follows naturally.
