Context

“This is why it is not right to say that pleasure is perceptible process, but it should rather be called activity of the natural state, and instead of 'perceptible' 'unimpeded'. It is thought by some people to be process just because they think it is in the strict sense good; for they think that activity is process, which it is not. (B) The view that pleasures are bad because some pleasant things are unhealthy is like saying that healthy things are bad because some healthy things are bad for money-making; both are bad in the respect mentioned, but they are not bad for that reason-indeed, thinking itself is sometimes injurious to health. Neither practical wisdom nor any state of being is impeded by the pleasure arising from it;” source
