"But communication is two-sided - vital and profound communication makes demands also on those who are to receive it... demands in the sense of concentration, of genuine effort to receive what is being communicated"

In this quote, Roger Sessions highlights the significance of reliable interaction and how it requires effort from both the sender and the receiver. He stresses that communication is not a one-way street, but rather a two-sided process. The sender must put in the effort to convey their message plainly and efficiently, while the receiver needs to likewise make an effort to truly understand and soak up the message being communicated. This requires concentration and real effort from the receiver, as they must actively listen and engage with the message. Sessions recommends that without this mutual effort, interaction can not be truly meaningful and impactful.
