A walk across sand sounds like the calmest subject a poem could pick, but in Dave Bonta's "Mutability" the ground will not stay put. The speaker walks on sand "that everywhere changes its place," announces flatly "I believe nothing," and then slips into a strange, almost surreal picture of eyes hurting the winter "in green spectacles." The poem's central idea seems to be that nothing in the world is fixed, and that our way of looking is no more fixed than the world. The title says as much. Mutability means the capacity to change, and the poem applies it twice: to the landscape and to the person perceiving it.
The opening is deliberately plain. "I go for a walk in the sand" is the kind of sentence anyone could say, and its loose, rocking rhythm, with roughly three beats and a few unstressed syllables between them, feels like unhurried steps. The second line starts to unsettle that calm. "Everywhere" is a big, sweeping word for such a small scene, and "changes its place" is a quietly odd phrase, because we expect sand to be what things rest on, not something that relocates. The long *a* sounds in "changes" and "place," along with the hissing *s* sounds in "sand," "changes," "its" and "place," give the line a soft, sliding quality, as if the sound itself were drifting. Nothing rhymes in the poem, and that suits it, since rhyme would give the ear a sense of arrival the poem refuses to offer.
Then comes the shortest line, "I believe nothing," set apart as its own stanza. After two lines of description, the speaker suddenly states a position. The line can be read as a flat refusal to trust anything, which would make sense for someone standing on shifting ground. It can also be read as a small paradox, since "nothing" is the one thing the speaker admits to believing. The next stanza begins with a lowercase "eyes" and the poem has no punctuation, so the gap may work as a hinge as well as a full stop. Read straight across, the words become "I believe nothing eyes can hurt the winter," which suggests the speaker doubts what eyes can do. The poem never settles which reading is right, and the uncertainty enacts the mutability it names.
The final image is the most puzzling and the most memorable. We usually think of winter as the thing that hurts us, with its cold and its glare. Here the relationship is reversed, and "eyes can hurt the winter." Looking becomes an act that does something to what is looked at. The "green spectacles" make this concrete. Green is the colour of spring and growth, the opposite of winter's bleakness, so a pair of green lenses lays one season's colour over another. The idea echoes the familiar saying about seeing the world through rose-tinted glasses. The word "spectacles" has a second meaning as well: a spectacle is a show, a thing put on display. Whoever wears these glasses is both tinting the world and turning it into a performance. It is also unclear whose spectacles they are, the eyes' or the winter's, and that ambiguity adds to the sense that observer and observed are tangled together.
Put together, the three images make a quiet argument. The sand shifts, so the outer world offers no firm footing. The speaker declines to believe, so no inner certainty replaces it. And what remains is perception, which is shaky because it colours and alters whatever it touches. The poem moves from the physical (feet in sand) to the philosophical (belief) to the strange and visual (winter, spectacles), and each step takes away a little more stability.
The poem's significance lies in how much it does in so little space. In five short lines it manages a landscape, a statement of doubt and a puzzle about perception, and it never explains itself. A school reader might be frustrated by that at first, but the gaps are where the poem works. Because the syntax can be read more than one way and the images do not resolve, the reader ends up in the speaker's position, trying to find solid footing on ground that keeps sliding. The poem argues for mutability by making us feel it.
