Final answer:
The major drawback in using aesthetic modifications is that their value is subjectively determined, which is true. Aesthetic judgments rely on personal perceptions, though they can be informed by broader criteria as suggested by critics with refined taste.
Step-by-step explanation:
The statement that the major drawback in using aesthetic modifications is that their value is determined subjectively is True. The realm of aesthetics certainly is subjective as judgments about what is beautiful vary greatly from person to person, culture to culture, and can depend on a multitude of other factors like emotional state and personal experiences. Enlightenment philosophers such as Hume and Kant agreed that beauty is not an absolute quality inherent in objects but a subjective judgment that can differ based on individual perception. However, while aesthetic judgments are subjective, many believe they should not be entirely arbitrary; critics with educated and refined taste are often given more weight in determining the value of art.
According to Frank Sibley's argument, while aesthetic judgments are based on sensory observations, the translation of these into judgments requires sensitivity and discernment, implying that aesthetic appreciation is more nuanced than merely personal taste like that for ice cream flavors. Hence, although subjective, there are justifications for aesthetic judgments that go beyond mere personal preference.
