Context

“But "it is more pleasant to think of what we know, than to seek what we know not," as the Philosopher says (Ethic. x, 7) : since in the latter case we encounter difficulties and hindrances, in the former not; while pleasure arises from an operation which is unhindered, as stated in Ethic. vii, 12, 13. Therefore wonder hinders rather than causes pleasure.
Obj. 3: Further, everyone takes pleasure in what he is accustomed to: wherefore the actions of habits acquired by custom, are pleasant. But "we wonder at what is unwonted," as Augustine says (Tract. xxiv in Joan.) . Therefore wonder is contrary to the cause of pleasure.
On the contrary, The Philosopher says (Rhet. i, 11) that wonder is the cause of pleasure.
