How to set "all values" as default in a multiple select?

Question

There are questions on how to make one selection default, like this one. But I have a multiple select and want all the options to be selected initially. I found questions for something similar (like this), but not exactly what I want.

Is this possible without JavaScript?

<select multiple>
    <option selected>a</option>
    <option selected>b</option>
    <option selected>c</option>
</select>
