Here it is certain, that the utility or importance of itself causes no real passion, but is only requisite to support the imagination; and the same person, who over-looks a ten times greater profit in any other subject, is pleased to bring home half a dozen woodcocks or plovers, after having employed several hours in hunting after them.

To make the parallel betwixt hunting and philosophy more compleat, we may observe, that though in both cases the end of our action may in itself be despised, yet in the heat of the action we acquire such an attention to this end, that we are very uneasy under any disappointments, and are sorry when we either miss our game, or fall into any error in our reasoning.
If we want another parallel to these affections, we may consider the passion of gaming, which affords a pleasure from the same principles as hunting and philosophy.

It has been remarked, that the pleasure of gaming arises not from interest alone; since many leave a sure gain for this entertainment: Neither is it derived from the game alone; since the same persons have no satisfaction, when they play for nothing: But proceeds from both these causes united, though separately they have no effect.

It is here, as in certain chymical preparations, where the mixture of two clear and transparent liquids produces a third, which is opaque and coloured..
The interest, which we have in any game, engages our attention, without which we can have no enjoyment, either in that or in any other action.
Our attention being once engaged, the difficulty, variety, and sudden reverses of fortune, still farther interest us; and it is from that concern our satisfaction arises.

Human life is so tiresome a scene, and men generally are of such indolent dispositions, that whatever amuses them, though by a passion mixt with pain, does in the main give them a sensible pleasure.
