"For, usually and fitly, the presence of an introduction is held to imply that there is something of consequence and importance to be introduced"

Arthur Machen's quote highlights the significance often attributed to introductions in different forms of communication, be it in literature, speeches, or other contexts. At its core, the declaration recommends that the really existence of an introduction is an indication that what follows is of significant value or brings a certain weight.

The use of the words "usually and fitly" suggests that, as a general guideline, the existence of an introduction is not just customary but appropriate. It sets an expectation for the audience that what they are about to engage with is worthy of their attention. Intros serve several essential functions: they provide context, lay out the purpose, and prepare the audience for what is to come. In doing so, they establish a framework or a lens through which the subsequent content can be comprehended and valued.

For example, in literary works, an intro can serve as a guide, providing insights into the styles, background, or the author's intent, therefore enhancing the reader's experience. Likewise, in public speaking, a well-crafted intro catches the audience's attention, establishes reliability, and sets the phase for the primary message.

Machen's assertion also touches on the idea of repercussion and significance. These terms suggest that the following content carries a sense of gravity or significance, demanding the audience's engagement and reflection. This could be due to its possible effect, the depth of its insights, or its capability to affect viewpoints or provoke idea.

In essence, the quote highlights the role of intros as a bridge between the audience and the product, ensuring that the subsequent discourse is not just received, but is expected with a mindset poised for something significant. It advises us of the power intrinsic in a well-conceived intro to elevate the reception and understanding of any substantial communication.
