Changing societal values have a significant impact on both artistic expression and interpretation. As societies evolve, their values, beliefs, and norms also change, which is often reflected in the arts. For instance, the shift from classical to modern and postmodern art mirrors changes in societal attitudes towards tradition, authority, and individuality. Contemporary issues such as environmental concerns, social justice, and digitalisation are increasingly finding expression in art. These changes not only influence the themes and subjects of artistic works but also the techniques and mediums used. Furthermore, societal changes affect how art is interpreted and valued. What was once considered avant-garde or controversial may become mainstream, and vice versa. This dynamic relationship between society and art highlights the arts' role in both reflecting and shaping cultural and societal narratives.

Art, despite its subjective nature, can be considered a reliable source of knowledge, though this reliability is of a different nature compared to empirical sciences. Artistic knowledge is rooted in personal experiences, emotions, and cultural contexts, offering insights into the human condition that are often inaccessible through purely objective means. The subjective aspect of art allows for a diversity of interpretations and meanings, which is a strength rather than a weakness. It enables art to communicate complex ideas and emotions, providing a deeper understanding of societal values, historical contexts, and personal experiences. While the knowledge gained from art may not be universal or quantifiable in the same way as scientific knowledge, it is equally valid in its ability to enrich our understanding of the world and ourselves. Therefore, acknowledging the different types of knowledge and their respective contributions is essential in appreciating the reliability and value of art as a source of knowledge.

Different art forms utilise non-verbal language in unique ways to convey knowledge, each offering distinct modes of expression and communication. In visual arts, elements like colour, form, and composition convey emotions and concepts, allowing for a visual dialogue between the artist and the viewer. In music, melody, harmony, rhythm, and dynamics express ideas and feelings that transcend linguistic barriers. Dance and physical theatre use body movements, gestures, and expressions to communicate narratives and emotions, often telling stories or conveying messages without spoken words. Cinema combines visual imagery, music, and narrative techniques to create a multi-sensory experience. Each of these art forms uses non-verbal language to engage the audience, evoke emotional responses, and convey knowledge that might be difficult to articulate through words. This diversity in expression showcases the versatility and depth of non-verbal communication in the arts, underscoring its importance in conveying complex and nuanced knowledge.

Technological advancements have profoundly impacted the methods and tools used in the arts, continually expanding the boundaries of artistic expression and interpretation. The advent of digital technology, for instance, has introduced new forms of art such as digital painting, 3D modelling, and virtual reality art. These technologies allow artists to experiment with new mediums and techniques, pushing the limits of traditional art forms. Furthermore, technology has changed the way art is produced, distributed, and consumed. For example, digital platforms enable artists to reach a global audience, altering the dynamics of art appreciation and criticism. Moreover, technology has influenced the sensory experience of art, offering new ways to engage with and interpret artistic works. This evolution raises questions about the changing nature of artistic knowledge and the role of technology in shaping our understanding of what constitutes art.

Cultural differences play a significant role in shaping the interpretation of artistic methods and conventions. These differences stem from varied historical, social, and cultural backgrounds, influencing how individuals perceive and interpret art. For instance, the use of colour, symbolism, and narrative in art can be interpreted differently across cultures. What may be considered a symbol of peace in one culture could represent something entirely different in another. Additionally, artistic conventions, like the style of brushwork in painting or the structure of music, are often deeply rooted in cultural traditions. Therefore, an understanding of these cultural nuances is crucial for a comprehensive interpretation of art. This complexity adds to the richness of the arts as an area of knowledge, highlighting the importance of cultural context in shaping our understanding and appreciation of art. It challenges the notion of universal standards in art and encourages a more inclusive and diverse understanding of artistic expression.
