Context

“The opposite of laughing and joking is seriousness. Accordingly it consists in the consciousness of the perfect agreement and congruity of the conception, or thought, with what is perceived, or the reality. The serious man is convinced that he thinks the things as they are, and that they are as he thinks them. This is just why the transition from profound seriousness to laughter is so easy, and can be effected by trifles. For the more perfect that agreement assumed by seriousness may seem to be, the more easily is it destroyed by the unexpected discovery” source
