Yann Martel
The reason death sticks so closely to life isn't biological necessity-it's envy. Life is so beautiful that death has fallen in love with it, a jealous, possessive love that grabs at what it can. But life leaps over oblivion lightly, losing only a thing or two of no importance, and gloom is just a passing shadow of a cloud.
To choose doubt as a philosophy of life is akin to choosing immobility as a means of transportation.
