"For my own part I think no innocent species of wit or pleasantry should be suppressed: and that a good pun may be admitted among the smaller excellencies of lively conversation"

In this quote from James Boswell, he advocates for the addition of humor in conversations, especially singling out the pun as a worthwhile aspect of wit. Boswell reveals a preference for "innocent" kinds of humor, recommending that lively wit and pleasantry that don't hurt or offend ought to be welcomed in discourse. By utilizing the word "innocent", Boswell underscores the value of keeping humor light-hearted and benign, most likely to keep a positive and inclusive environment.

Boswell refers to a "excellent pun" as a "smaller sized quality of vibrant discussion". This expression suggests that while puns may not be viewed as highbrow or advanced on the same level as other forms of intellectual repartee, they still hold worth within social interactions. Puns, as a type of wordplay, require a specific level of linguistic creativity and a capability to engage with language in an inventive way. Although they might be considered simple and even unimportant by some, Boswell values them for their capability to include energy and pleasure to discussions.

Moreover, Boswell acknowledges that dynamic conversation is improved by these "smaller sized excellencies". This indicates that the value of a conversation is not exclusively figured out by its depth or severity but likewise by the elements that bring joy and vivacity to the interaction. In this way, Boswell's perspective is inclusive, recommending that intellectual and light-hearted elements can exist side-by-side, each contributing to the characteristics of discussion in their own way.

In general, Boswell's quote conveys his belief that humor, specifically puns, plays a significant role in enriching social exchanges. He champs the idea that wit, in its many kinds, should be celebrated rather than stifled, as it boosts the vibrancy and enjoyment of human interaction.
