But although silence and seclusion and absolute freedom of mind are devoutly to be desired, they are not always within our power to attain. Consequently we must not fling aside our book at once, if disturbed by some noise, and lament that we have lost a day: on the contrary, we must make a firm stand against such inconveniences, and train ourselves so to concentrate our thoughts as to rise superior to all impediments to study. If only you direct all your attention to the work which you have in hand, no sight or sound will ever penetrate to your mind.

If even casual thoughts often occupy us to such an extent that we do not see passers-by, or even stray from our path, surely we can obtain the same result by the exercise of our will. We must not give way to pretexts for sloth. For unless we make up our mind that we must be fresh, cheerful and free from all other care when we approach our studies, we shall always find some excuse for idleness.

Therefore, whether we be in a crowd, on a journey, or even at some festive gathering, our thoughts should always have some inner sanctuary of their own to which they may retire. Otherwise what shall we do when we are suddenly called upon to deliver a set speech in the midst of the forum, with lawsuits in progress on every side, and with the sound of quarrels and even casual outcries in our ears, if we need absolute privacy to discover the thoughts which we jot down upon our tablets? It was for this reason that Demosthenes, the passionate lover of seclusion, used to study on the seashore amid the roar of the breakers that they might teach him not to be unnerved by the uproar of the public assembly.
