Institutio Oratoria

Having dealt with writing, the next point which claims our attention is premeditation, which itself derives force from the practice of writing and forms an intermediate stage between the labours of the pen and the more precarious fortunes of improvisation; indeed I am not sure that it is not more frequently of use than either. For there are places and occasions where writing is impossible, while both are available in abundance for premeditation. For

Again, this practice will not merely secure the proper arrangement of our matter without any recourse to writing, which in itself is no small achievement, but will also set the words which we are going to use in their proper order, and bring the general texture of our speech to such a stage of completion that nothing further is required beyond the finishing touches. And as a rule the memory is more retentive of thoughts when the attention has not been relaxed by the fancied security which results from committing them to writing. But the concentration which this requires cannot be attained in a moment or even quickly.

For, in the first place, we must write much before we can form that ideal of style which must always be present to our minds even when engaged in premeditation. Secondly, we must gradually acquire the habit of thought: to begin with, we shall content ourselves with covering but a few details, which our minds are capable of reproducing with accuracy; then by advances so gradual that our labour is not sensibly increased we must develop our powers and confirm them by frequent practice, a task in which the most important part is played by the memory.
