The “purposive” man ... does not love his cat, but his cat’s kittens; nor, in truth, the kittens, but only the kittens’ kittens, and so on forward forever to the end of cat-dom. For him jam is not jam unless it is a case of jam to-morrow and never jam to-day.

Yet they've proved that common men can show astonishing fortitude in chasing jam tomorrow.

It always seems to be a problem to be dealt with when resources (later) permit. Jam tomorrow, as usual.

The consumption-possibilities curve illustrates the choice which must be made: more jam today means less jam tomorrow; less jam today means more jam tomorrow.

A basic human characteristic is the preference for consumption today over consumption tomorrow. Jam today is always better than jam tomorrow, unless sufficient incentive is offered to forgo the immediate enjoyment of today's jam. This is not because of uncertainty about the likely receipt of tomorrow's jam, but merely a property of the passage of time.

For one-period optimization, the obvious course of action to maximize consumption is to consume the whole of output by “eating up” the capital stock. The inapplicability of this tactic to an industrializing nation is transparent—it gets a lot of jam for today but leaves little for tomorrow. Jam today has therefore to be balanced against jam tomorrow.
