There is a tide in the affairs of man
Which, taken at the flood, lead on to fortune;
Omitted, all the voyage of their life
Is bound in shadows, and miseries.

Cassius, urging Brutus to join the struggle to remove Caesar before he grows into tyrant

Casca, urging that the conspirators explain their cause to the populace before their motives are misunderstood

Messala, urging Titinius to search for Pindarus.
