This quote encapsulates the human tendency to constantly seek pleasure and satisfaction. The first part, "Pleasures are ever in our hands or eyes," suggests that we are always surrounded by potential sources of joy and satisfaction, whether it’s something we can physically touch or merely see. Meanwhile, the second part, "And when in act they cease, in prospect rise," implies that once a source of pleasure is exhausted or has run its course, we immediately start looking for the next one.

The quote suggests a cyclical nature of pleasure-seeking, where the pursuit of one pleasure leads to the anticipation of the next. It paints a picture of humans as beings constantly in motion, never fully satisfied, always yearning for the next source of happiness or satisfaction. This can be seen as both a blessing and a curse – on one hand, it drives progress and prevents stagnation; on the other, it can lead to a never-ending chase for ephemeral joys, never truly appreciating what we have in the present moment.

In today’s world, this idea is more relevant than ever. In an era of instant gratification, where pleasures – be it food, entertainment, or shopping – are just a click away, we are constantly hopping from one source of pleasure to another. This can lead to a lack of contentment and a sense of emptiness, as we’re always looking for the next thing rather than appreciating what we have.

In terms of personal development, this quote can serve as a reminder to be more mindful and present in our pursuit of pleasure. It encourages us to savor the moment and appreciate the pleasures we have, rather than constantly seeking the next. It can also serve as a warning against overindulgence and the potential emptiness that can come from a life solely focused on seeking pleasure. Instead, we can strive for a balanced life, where pleasure is a part, but not the whole, of our happiness.
