All of these rebels against reason make the mistake of supposing that the aim of reflective thinking is to quell instincts, which, with the best will in the world, it cannot succeed in doing. Instincts are present and powerful. In themselves they are neither worth encouraging, nor ought they to be repressed. The satisfaction of native desires _is_ what we want. The importance of reflective thinking is precisely that it helps us to secure those satisfactions. To surrender to every random impulse or every habitual prompting is to have neither satisfaction nor freedom. Reflection might be compared to the traffic policeman at the junction of two crowded thoroughfares. If everyone were to drive his car pell-mell through the rush, if pedestrians, street cars, and automobiles were not to abide by the rules, no one would get anywhere, and the result would be perpetual accident and collision. In thinking we simply control and direct our impulses in the light of the consequences we can foresee. To thus guide and control action makes us genuinely free. If a man's actions are not guided by thoughtful conclusions, they are guided by inconsiderate impulse, unbalanced appetite, caprice, or the circumstances of the moment. To cultivate unhindered, unreflective external activity is to foster enslavement, for it leaves the person at the mercy of appetite, sense, and circumstance.[1] [Footnote 1: Dewey: _How We Think_, p. 67.] Instincts and habits are fixed responses; being placed in such and such circumstances we _must_ do such and such things. Only when we can vary our actions in the light of our own thinking are we masters of our environment rather than mechanically controlled by it.
